411 – Good Nerves Matter: GSD Working Dogs and Family Companions
Good Nerves Matter: GSD Working Dogs and Family Companions
Host Laura Reeves dives into the world of IGP and working German Shepherds with Malinda Weber, Czech/East German working line German Shepherd breeder in Kansas.
IGP was created originally as “essentially a breed test for the German Shepherd dog,” Weber said. “It tests the dog’s ability to work independently of its handler through tracking, which obviously makes the dog useful in other venues such as police work. It tests the dog’s ability to handle stress and pressure through obedience and protection work. And to perform a task where the dog was being able to be used to subdue or handle subjects without using lethal force.
“(The testing) starts with the BH. The BH is essentially an obedience test and temperament test showing us that the dog has proper nerve and capability to have a relationship with its handler. (They) perform just basic levels of obedience that would make the dog a family companion dog. Once the dog passes its BH, the dog is allowed at that point to progress onto the IGP title.
“Most people who have had dogs of any breed would know there are some dogs that have issues with gunfire,” Weber said, “They have issues with vacuums. They have issues with fireworks. … There’s some people that say ‘hey when people walk into my house, my dog barks a couple times and then takes off running for the other side of the house.’ Our breed should be bold. It should be confident and when things like that are happening, regardless of whether it’s gunshots or fireworks or someone knocking on our door, our dog should go forward and say ‘I’m here. I’m letting you know that I’m here. I’m not afraid of you and I’m willing to be protective of my thing, regardless of whether it’s my person, my home, or my sheep that I’m supposed to protect.’
“Our breed is described as being a confident, aloof, bold, not easily startled type of dog. Those good nerves that we want in our breed is something that a lot of people seem to overlook when it comes down to ‘just a family companion.’ Even if you just want a wonderful family companion, that is one reason why we would encourage people to look for the Breeders who are still testing their dogs in manners such as IGP. Because even if you’re just looking for a family companion, you want to make sure that the breeder you’re purchasing your puppy from has tested the parents and the puppies for all of these things, so that you can have the most wonderful possible family companion that you can enjoy long-term.”
Enjoy this deep dive into a fascinating sport and the versatile GSD.
410 – Jim Moses and Deborah Stern on German Shepherd Dogs
Jim Moses and Deborah Stern on German Shepherd Dogs
Legendary German Shepherd Dog breeders Jim Moses and Deborah Stern are responsible for the careers of some of the most famous dogs in AKC history. Dogs who are known worldwide by just their call names. Rumor. Hatter. Mystique.
Stern, president of the German Shepherd Dog Club of America and owner of Rumor, and Moses, who handled some of the top-winning dogs of all time, join host Laura Reeves in this first of two episodes to do some myth busting, talk breeding and share their passion for the breed.
“Our German Shepherd is the most versatile of dogs in the world,” Stern said. “It’s the only dog that is trained in multiple venues and actually performs, not just in performance or companion sports, but as a working dog. So, when a dog is trained, for example, for the police force, he’s not just trained in attack work, he’s probably also trained in scent discrimination of drugs. He’s also possibly trained in discrimination of incendiaries like bombs, things like that. He can be trained in multiple venues, and at the same time he can go out and search for a young child and find that child and be gentle when he finds it.”
“I think that the most important part of the German Shepherd,” Moses said, “and the thing that I fell in love with as a child, is the fact that they had complete dedication to me and always wanted to please. They’re probably the most biddable dog that I know of. By that I mean they want to do your bidding, no matter what it is you ask of them, they are ready in a second to do that work. So once they’ve learned how to do that bidding, they’re willing, anxious and desire to constantly please and so I think that that’s probably the most important part of the German Shepherd. I was born and raised in Western New York. As a teenager, we would go hunt pheasant and it didn’t take them long to learn to flush him and retrieve the birds.”
“I own Rumor,” Stern said, “who has won at Westminster and Eukanuba, best in show. She had several litters and many of those puppies have been placed in a service capacity. So, while she might have been a show dog in her lifetime, she is still genetically predisposed to be able to have dogs that are great working dogs out of her and are able to perform in a service manner. (Another) example is a dog that Jim actually bred that went on to be a service dog for a veteran. He had some damage to one of his legs and she helps him with his mobility.”
Stern and Moses both lauded the breed’s service to mankind for decades in a vast array of capacities.

409 – Prepping for Dog Events in a Masked Society
Prepping for Dog Events in a Masked Society
Vicki Ronchette from Show Dog Prep School joins host Laura Reeves for a conversation on counter conditioning dogs for shows in which the judge and everyone else is wearing a mask.
Dogs read humans’ facial expressions and body language as their primary form of communication, so masked strangers may be a challenge for certain breeds or individuals.
Ronchette, who works as a pet groomer, said her recent experience at her grooming shop was that most dogs took the masked staff in stride.
“First I think we have to identify if we have an issue,” Ronchette said. “We’ve seen actually a much lower incidence that we expected of dogs reacting to the mask. That being said, usually (the owner is) handing the dog to us. I was actually shocked. I thought it would be much worse than we are seeing. So I’m happy that a lot of the dogs don’t seem to be having a big reaction to it.
“I think the difference is going to be in dogs that are bred to be really, really visually on point like herding breeds where they are so ingrained to notice anything that’s not right.
“(It’s) gonna be a lot of new stuff to deal with. One of the things that remains true, that hasn’t changed, is dogs need to be able to handle whatever is thrown their way. The work that we do with puppies the work that we do with our young dogs all of that is going to pay big benefit now when there’s new and different things for them to become accustomed to.
“I think another thing that I want to touch on and I think gets left out of the equation more often than it should and that is us. Because dogs feed on our energy. Are we stressed out because we’re at this dog show that isn’t running the way we think it should? Are we stressed out because we have concerns about our health but we really, really, really, really, really want to be at a dog show? Or are we nervous about something? And remember that just being nervous about being in the ring is bad enough. Now let’s add nerves about a more impactful situation and remember the dog feels that.
“All of us, the judges, exhibitors, the experienced handlers, the new people, this is all new for all of us. Everybody’s figuring this out. So, it’s almost like it’s leveled the playing field.”
***
We’re all in this together, crew, and having to figure out our new reality. It makes me think of the idea of extending grace. Give the dog a little bit of grace. Give the judge a little bit of grace. Extend grace to the other exhibitors, the Superintendent, the show chairs. Stay safe and healthy friends.
408 – Janina Laurin Reflects on a Lifetime in Dogs, the Belgian Breeds
Janina Laurin Reflects on a Lifetime in Dogs and the Belgian Breeds
Second-generation Belgian Tervuren breeder and judge, Janina Laurin, joins host Laura Reeves for a conversation about the four Belgian herding breeds, including the newly recognized Belgian Laekenois.
Between the four breeds, the basic differences are coat and color, Laurin said, “But the basic premise is the same they should look like Belgian breeds. So they should all be elegant. You should always recognize them for what they are. I always say that if you see them in the field, regardless of which one they are, they should take your breath away… with stand-up elegance and alertness and confidence. That’s critical to all of what the Belgians are. I think initially so many people came to the (Belgian Tervuren) because of their color. When the sun hits that mahogany and black or rich fawn, it is just striking. They certainly have elegance about them and they’re all very sturdy.
“Temperament-wise, I would say the temperament is basically the same on all of them. the personality may be slightly different. I attribute all of that to individual breeding in the direction of where the Breeders have taken their dogs. I like to say a common characteristic between all of them is not so much high drive, as biddability. That’s the most critical factor for someone who’s looking for a family pet or show dog or companion is that they are biddable.
“They want to work with you, they want to do things for you. It is up to you as the owner to embrace that and make it stronger so it’s up to the owner to bring out the best in each dog.
“They like to do things… The dogs want to work and have heart. If you ask them, they’ll do it for you. …. (But) they have off switches. They’re not so high strung that they have their tongues out and eyes crossed waiting to do something.
“The Belgian breeds were developed as all around farm dogs, herding sheep and/or cattle, moving stock from farmyard to pasture and back again. The Laekenois, specifically, his primary duty was to guard the beautiful linens of Belgium and the Flemish people.”
Laurin offers outstanding insights for owner handlers and encouragement for those who are frustrated that their rare breed struggles to place in groups.
407 – Canine Action Photography Tips, Tools and Rules
Canine Action Photography Tips, Tools and Rules
Action photographer Bret Cody joins host Laura Reeves to talk great photos and how to capture them yourself.
Bret’s Action Photography rules:
Rule #1: Get down to eye level (it’s painful, but it’s worth it.)
Rule #2: Pay attention to your background.
- Attempt to pick a complimentary color. This is harder outside than in.
- Inside you can make your own photo “studio”, go out and buy a few yards of felt.
- For light colored dogs, pick a darker background.
- For darker colored dogs, pick a lighter background (you’re going for contrast here).
Outside the time of day can help: - need a lighter background pick some sunlit shrubbery,
- need a darker background pick some shaded shrubbery… Make sure the dog is in the light
- Put some space between your dog and the background.
- Ideally you (with your camera) should be closer to your dog than the dog is to the background. That might require a lot of space, plan for it. Take some test shots and decide how far you need to be from the dog (with your chosen gear), then look for something a little larger than double that. Doing this will set you up for some nice “bokeh” or a blurring of the background. If you can adjust your F-stop, adjust it to a fairly small number (1.5 is about max, but some gear will only reach 2.8 or even 3.5 – the idea is that the smaller the number the more effective the background blur will be.
Rule #3: My “secret weapon” Most dogs will respond to noises they can’t locate the source of. Go spend $1 on a squeeky toy. There are two ways of doing this: 1) hide the toy behind your back or under your arm 2) take the squeeker out of the toy and put it in your mouth (and simply blow through it). Get everything ready BEFORE you make any noise, it’s most likely that the picture you want will be the first split second after making the first squeek. What you are attempting to capture is “interest”. The dog (hopefully) will perk its ears, sit up straighter, and maybe look around in an attempt to find the noise. Looking at the camera is good, looking around the room isn’t so good, so be ready.
Rules for dogs in action
Rule #4: Shoot from a steadied position (if possible). A tripod, a fence post, even a friends shoulder (in a pinch). Making the camera (or phone) as steady as possible will help it get what you want in focus and keep it there.
Rule #5: Pick the spot you shoot from carefully. You want to see dogs, not shadows. Sometimes you don’t get a choice, but if you do, put the sun at your back. And don’t forget to move as opportunity allows. If you’re there for the day, the sun will move across the sky and you should
be moving with it.
Rule #6: Pick the spot you shoot from carefully. This time pay attention to what the dog(s) are doing and were they are doing it. My favorite photos are of dogs in stress. They’ve encountered a problem and have to think their way out of it. In my case it’s unruly sheep, but it can be tracking a thrown ball (or frisbee) or finding a ball after the bounce, maybe a corner they have to navigate at top speed. Whatever that stressor is going to be, you want to place yourself so that you’ll see their face (not their tail). And be able to photograph the dog while they are thinking.
Rule #7: A dog with “purpose” is a wonderful shot. The dog chasing a ball or frisbee has speed and purpose. Do NOT shoot the dog from behind. While it is exciting, a dog’s tail doesn’t make a good subject of a photo. My personal rule is that if I don’t see an eye it isn’t worth pushing the button on. If you have more than one subject in your shot (say a herd of sheep the dog is herding) then the more eyes the better, but the subject (mostly the dog, but that can change) had better have at least one eye in the shot. Hint: Be open for your subject to change. Sometimes another animal (sheep? cow? bird?) will do something that is absolutely amazing and swiftly changing to that action (and letting your “normal” main subject become a background subject) can get you amazing shots.
Rule #8: Study your tool. If you’re using a phone, what can it do? How does it do it? Can an app help gain more flexibility or control? If you’re shooting a camera what can it do and how does it do it? Does it have manual controls (can you pick the shutter speed, aperture, ISO, etc)? What do you have to do to tinker with those controls? The less control you have over the behavior of your tool the more you’ll have to adapt to it, to get the most from it. Camera manufacturers build for general use and shooting dogs in action is very specific. The more professional tools will be more adaptable to specific tasks. That doesn’t mean go out and spend $20,000. I’m not even saying go out and spend anything (other than $1 on a squeeky toy).
Use what you have available. Look at your results and decide for yourself what’s wrong with the picture. Then attempt to find a solution to your problem (with the tool you have). (Classes might be an option here, but mostly I find the instructor teaching the class how to be
“just like him” – and you need to know how to be a better you.) I’m pretty positive that you can be your own best instructor. You’ll need specific info and that is what the web is for, ask it. Read widely (one person will have one point of view and you need more than one point of view.) Go out and try what you’ve learned, fail, adapt and try again. You’ll end up a MUCH better photographer – the struggle is the lesson. Someday, you’ll have mastered your tool. You’ll find that it limits you. It just can’t do what you know can be done. THEN you should think about upgrading your tool. And by then you’ll have some solid information about your upgrade path.
Photography specific
Rule #9: Shoot in “action mode” or “sport mode.” If you have control over the settings of your camera, you’re looking for a fast shutter speed (I try to shoot faster than 1/1000th of a second). You need to stop the action (to prevent blur) and the easiest way is to simple shoot
as fast as possible. But short exposures mean your limiting the light that gets to the chip (film) (more about this in a bit).
Rule #10: Shoot as high an f-stop as possible. Larger numbers of F-stop mean more depth of field AND less light getting to the sensor. Understand that F-stop and aperture size are inversely proportional. Large number = small hole. So, if you’re shooting a fast shutter speed (which limits the amount of light) AND a large F-stop (which limits the amount of light) you can see the problem. At the settings you want, you’ve got no light to record.
Rule #12: (The third part of exposure) ISO. Higher ISO means making the imaging chip more sensitive to light. Higher ISO number mean you can have BOTH a fast shutter speed and a high F-Stop. The cost is “noise” (think error). The chip will get it “wrong” more often.
Rule #13 Shoot RAW. Think of it this way: Larger files = More detail. You want to capture as much detail as possible, and RAW will help you do that. JPG is a compression formula (to make smaller files and to save space) and so much of the detail captured by the chip is thrown out by
the computer.
Rule #14 Learn how to read and use the histogram. Learn about STTR (Shoot To The Right). The chip doesn’t see light the same way your eye does. So it records it differently. The histogram is a graph of what light was captured. To maximize the amount of detail, adjust the
exposure so the histogram is just about to go off the right edge of the scale. The pictures will look over exposed (because they are) and that’ll have to be fixed in editing. BUT it’s not hard to edit the exposure and keep all that detail. Oh and you’ll have to learn editing. It’s OK, you really do need a new hobby.
So, now you (and not your dog) experiences stress. How are you going to get the shot you want? What compromise is the right compromise? And it’s different for every situation. How YOU solve that problem is what makes YOUR art YOURS.
It’s not hard (or even difficult), but I’ll tell you there’s a lot of years of training (and mistakes) to get me to that point. It’s paying attention (sometimes that’s very hard for me.) It’s situational awareness (what’s happening on the field, what’s happening off the field, what’s happening behind me (did I block someone’s view and they are now upset at me? Do I need to move?) But in the end, once you get the settings, then you can work on your technique – camera steady, panning with the action, looking for eyes, behaviors on the field that tell me the dog is getting stressed (and to get ready to photograph a wreck…. this is a whole lot like NASCAR – the wrecks are horrible, but interesting.)
406 – Veterinary Voice: Scary weird stuff that happens to girl dogs
Veterinary Voice: Scary weird stuff that happens to girl dogs
Dr. Marty Greer joins host Laura Reeves for a conversation about some of the scary, unusual medical emergencies and conditions which can affect our breeding bitches. On our list are prolapsed uterus, vaginal hyperplasia, inguinal hernia with the uterus in it, torsioned uterine horn, ovarian tumor, and spay or don’t spay during a C-section.
Included below is Dr. Greer’s peer-reviewed submission on the topic of not spaying bitches on the table during a C-section.
Reasons NOT to spay your bitch at her c-section:
- Pregnancy is a uniquely thromboembolic event. This means she is more likely to form blood clots during late pregnancy and in the immediate post-partum period. All bitches, whether they have had a c-section or not, are at increased risk of developing blood clots. These clots, as in humans, can be life-threatening, particularly if they lodge in the heart or brain. If she were to be spayed at this fragile time, she is a greater risk of blood clots formed at the suture sites, increasing the risk of blood clots. This is the most common cause of death in the period shortly after a c-section.
- The bitch shares 1/3 of her blood volume with her puppies. Only a small portion of this shared blood volume will pass to the fetuses. Most is left in the uterine lumen or in the uterine wall and vasculature. Over time, this blood will be resorbed by the bitch to replenish her blood volume.
- During pregnancy, the blood flow to the uterus is expanded to support the pregnancy and placentas. When the blood vessels are ligated (tied off), her blood pressure is lowered. Some bitches as they recover from anesthesia and her blood pressure increases to normal, a blood vessel may leak or a suture may slip off, resulting in bleeding, which may either lead to the need for another interventional surgery, or if this is rapid and severe, she may die prior to getting her back to surgery.
- Additionally, all of the blood vessels in the broad ligament (where the blood vessels supporting the ovaries and uterus) need to be tied off. If any are missed, there will be bleeding and possible drop in blood pressure which can lead to death.
- When she loses blood rapidly from the removal of the uterus and ovaries (if she is spayed), she will suffer a rapid drop in blood pressure, which is likely to lead to cardiac and/or respiratory compromise or crisis during the procedure, leading to death.
- Depending on the surgeon and techniques used, performing a spay at the c-section will add at least 30 minutes to a c-section. This leads to a delay in her bonding to her pups and allowing them to nurse during this early and critical period when her pups need colostrum and energy.
- Be particularly wary if the veterinary staff wants to do an en bloc c-section – where they remove the uterus in its entirety with the pups still inside. This is an almost certain death sentence for your valuable litter.
- A second surgery for a spay is safer than a spay at c-section.

Black at the Dog Show. What you see and what it is.
“We can be opponents and not be enemies”
Professional handler Randy Benns joins host Laura Reeves for a frank and open discussion about race, dog shows, the past and the future.
Benns started in dogs working for the world-renowned Miss Dorothy Nickles.
Asked what his job was for Nickles, Benns laughed, “Whatever she said. Anybody that knows her knows that you just followed orders. I’d go to her house during the week sometimes and go to some of the dog shows with her. But I wasn’t really allowed out of her set up. I think she was fearful for me to be out of her set up, out of her sight. So, I stayed in the set up and fed, cleaned and all that stuff. The first thing she told me that I need to keep my nose clean, don’t get in any trouble.
On the question of “is the environment at dog shows better, worse or the same as the general population for people of color, Benns noted that “(Dog shows are) a microcosm of the United States itself. So, it depends on the group of people you’re around. I’ve been able to make some great friends.
“I surround myself with people that I can trust because I’ve seen the ugly side of it. If I had a child would I want him to show dogs? I’d say not until he’s an adult. Some people sugarcoat it and say it wasn’t tough. It was tough. The little sides of racism that nobody wants to talk about. Lisa’s seen people come up to me and ask if I could go over their dog because their dog hasn’t seen a black person, and the judge they have is black. I never understood that because I’m thinking ‘why would a dog care? They just want somebody to be nice to them and feed them.’ So, I’ve had that before, more times than I can count.
“At the dog show, if you’re around a certain group of people, them saying the N word under their breath or … when I first started dating (my wife, Lisa) they said ‘is that N word dating that white girl. But they didn’t say dating. They put it different…”
Benns shares many of the highlights and lowlights of a long and accomplished career as a black man in purebred dogs. Would he have won more if he was white? Yes. The least likely person who had his back. Eddie Boyes. The first blatant, out loud example of racism he personally experienced. The day-in, day-out experience of institutional racism, as well as the more overt instances.
This is a timely, important, thought-provoking and long overdue conversation. I invite you to join us.

404 – The Athletic, Wicked Smart, Primitive Xoloitzcuintli
The Athletic, Wicked Smart, Primitive Xoloitzcuintli
Host Laura Reeves visits with passionate fanciers Barbara Griffin and Giovanna Suedan, a self-proclaimed “xolo-aholic,” about the Xoloitzcuintli.
According to the Xoloitzcuintli Club of America, this is “one of the world’s oldest and rarest breeds, with statues identical to the hairless variety dating back over 3,000 years. These clay and ceramic effigies have been found in tombs of the Mayan, Colima and Aztec Indians. The Aztecs deeply revered the Xolo and believed the breed to have mystical healing abilities.” Columbus even mentioned encountering strange hairless dogs in his 1492 New World journals.
Xolos are recognized in three sizes and two coats, according to Griffin, who was instrumental in the breed’s recognition by the American Kennel Club in 2011. The Xoloitzcuintli was actually first registered with the American Kennel Club (AKC) from 1887 to 1959 as the “Mexican Hairless” breed, but was dropped due to insufficient numbers of dogs being bred and registered.
“I always mention this,” Suedan said. “(The breed) might be really old, but if you compare it to breeds that have been worked on, it’s not as old. It was out of extinction in the early ‘90s. So from the ‘90s to now, it’s not a long time ago. In the beginning, we had very few dogs, very few breeders. They were doing a great job trying to rescue the breed. (But) now the numbers are stable and now we have to standardize (breed) type.”
Size matters
“I find my standards are much more territorial and much more protective,” Griffin said. “If I am going someplace at night, I would rather have my standard xolo with me than my Anatolian Shepherd. They’re very, very territorial. When you walk into my kennel from the little one on up to the biggest one they’re barking. Take some (of them) out and they’re “hi there, how are you, I was a Golden retriever in another life.’”
“Mine are all very friendly,” Suedan said. “But they’re very, very socialized. The key to this breed, because they are primitive, is socialization, socialization, socialization. They’re not a keep in your backyard dog and then think you’re going to take the dog to the park.”
Hairless or coated
“I used to think that they need a lot of lotion, a lot of sunscreen and a lot of care,” Suedan said. “Eventually I realized that it’s also genetic and feeding has a lot to do with it. I don’t use as much lotion as I used to and I don’t use sunscreen even though I do have a spotted dogs. They do burn if you let them outside all the time. Some dogs are allergic to some cleaning products.
“Puppies (skin) are soft. They break out, so they get like little pimples and then they outgrow it. The big key is good quality food. Each dog feels different but they’re very smooth, almost like a chamois. I mean just a very, very smooth. It feels like fine leather.”
Griffin adds, “Their skin is very tough. Veterinarians have to not freak out when the needle bends when they get a shot.”
Coated dogs can pop up in a variety of manifestation, Griffin noted. “You want a short harsh coat. They do not have an undercoat. You can get a variety of different coats. My first standard there were two coated females (in the litter) that looked like Australian Shepherd mixes. Like a Golden retriever, but fluffier. You can get a coat that looks like a bearded collie. You can get a coat that looks like a rough coat Jack Russell.”

403 – Virtual Reality: Step by Step to a Rally Title for Your Dog
Virtual Reality: Step by Step to a Rally Title for Your Dog
Trainer Gabi Vannini from What A Great Dog! walks us through the process to earn a virtual rally title for your dog. Below is a short excerpt from our conversation. Listen in to the podcast for excellent training tips, rally performance do’s and don’ts and more.
“You can submit videos for your rally novice title,” Vannini said. “So the entry level rally, you can submit three videos and get an actual rally title. It’s the same as if you went to a trial. You would have to get three qualifying legs. They’re having judges actually score these runs and look at them, so it’s not just a pass/fail. You’re actually getting your score out of 100 on that and having to do it just like you would in a trial. They’ve got five different courses that you can pick from to try out. They’ve set courses for you and you can do it in your backyard or your local park. If you have a local training building that you can rent the ring out, I know that’s what a lot of people have been doing, but you can get creative with it. Wherever you can fit a reasonably sized rally course and either set up a tripod or get someone to video for you and submit to AKC and get your actual rally novice title.
“(AKC has) been really helpful with … the rally maps. (They) have a specific spot on the map, ‘place camera here’ so that they can get the best view for the judges to be able to look at it. They’ve got the maps laid out for you. All five maps that you can pull up and use. They’ve got a really simple way to submit everything. They got their instructions and all of that right there. They’ve got a nice little how to perform the rally sign setup for you, so it’s really making it very accessible for people who are wanting to try something different with their dog.
“I think this is going to be a really good opportunity. For people that know rally and do rally, you can fly through these if you want to. But I think it’s a really nice thing for people that maybe have done some of those trick titles or CGC … and now they have something a little more that they can learn about and do at home. By the time we get rolling back in dog shows, maybe they’ll want to jump up and go into rally intermediate, where it’s similar signs and are still on leash and see how things go.
“You always are gonna get the people that are gonna say that it’s gonna cheapen their rally title that they got. All things change. I got an Open title with my dog and no where does it say on my title certificate that he did the long stay in a group. Just because somebody can go do a virtual rally, it doesn’t mean yours is less. Those people aren’t competing with you. If you’re real serious about your rally and you want to get like 100 points on everything, wait for a dog show. The people who are being brought in by this rally virtual program, they’re not your competition. You don’t need to look at them as some kind of threat.”
402 – Insight on the Genetics of Hairlessness in Dogs
Insight on the Genetics of Hairlessness in Dogs
Adam Boyko, Chief science officer and co-founder of Embark, joins host Laura Reeves to talk about the Fox I3 gene, that causes hairlessness in many dog breeds.
“So it’s a gene that’s gonna be involved in what we would call ecto dermal differentiation,” Boyko said. “So it’s going to affect a lot of tissues that are in the ectoderm. Not just hair follicle formation but also things like the inner ear or the sweat glands or dentition. All of these things that are related because they’re coming from the same developmental tissue.”
“The canine genome was first sequenced in 2005, so we have a reference genome now from Tasha the boxer and this was a big $25,000,000 project,” Boyko noted.
“(Some of) my colleagues worked on it. This was before I got into dog genetics. I was graduating from Purdue with a degree in biology but I was studying butterflies at the time. So I didn’t join the dog field until after we had a genome. I switched because there’s so much more cool stuff you can do with an organism that has a genome and particularly with dogs.
“In 2008 (researchers) were able to identify the gene that’s different between dogs that are hairless and dogs that aren’t. This Fox I3 gene. The mutation itself is just this insertion of seven base pairs. Remember, the genome is like 2 1/2 billion base pairs. So that little mutation then is the difference between whether the dog has hair or doesn’t.
“One of the projects I started out with … we call the village dog project. Most of the dogs in the world aren’t purebred dogs and they’re not even mixed breed dogs the way you and I think of mixed breed dogs. They’re actually natural populations of dogs that have been around for thousands of years and probably have some really interesting biology. If you look at village dogs across the new world, you do occasionally come across dogs that carry this mutation and have the hairless phenotype. If you look at dogs that have a very, very similar sequence, so that the same genetic background but don’t have the mutation, these are the closest relatives for where the mutation occurred for dogs that don’t have the mutation. It’s actually like Alaskan Huskies and other northern dogs that are very puffy, puffy dogs, but they have DNA still in them that pre-Columbian Native American dogs had.
“Genetically you get the signature that this is a mutation that arose in the new world before European contact and this is the basis for Mexican hairlessness right so the Xolo, the Peruvian Inca Orchids, as well as the Chinese Crested.
Two copies is deadly
“This mutation is actually lethal. A dog with two copies of the mutation dies in utero. So, every hairless dog has one copy of the broken Fox I3 gene and one good copy of the Fox I3 gene.
“The “powder puff” have better dentition. This Fox I3 mutation not only effects the development of hair follicles and interrupts them throughout most of the body, but the dentition is also affected. The teeth, both the deciduous teeth and the permanent teeth, generally you don’t see as many developed, they’re not as well formed, they tend to be more conical, they’re a little more tusk like, they point out a bit more. These are all kind of developmental defects. The powder puff doesn’t have these defects, not because it has a better Fox I3 gene that you want to breed in, it just doesn’t have the broken one.”
Evolutionary purpose of hairless dogs
“I think ultimately the purpose is that people really like unique and distinctive dogs,” Boyko said. “You have this mutation which has a dominant effect, so as soon as it arose that dog was hairless. And it arose in an environment where people thought that this was a sacred dog or a dog that they wanted to have around.”
From XCA:
“A uniquely New World breed, the Xoloitzcuintli stands out for being hairless, although there is a coated variety. The Xoloitzcuintli was one of the earliest breeds to be added to the American Kennel Club studbook – in 1887 under the name “Mexican Hairless”. This is a robust and healthy breed that evolved in the primitive jungles of Colima, Mexico. Archaeological evidence has been found in the tombs of the Colima, Mayan, Toltec, Zapoteca, and Aztec Indians dating the breed to over 3500 years ago. Long regarded as guardians and protectors, the indigenous peoples believed that the Xolo would safeguard the home from evil spirits as well as intruders. In ancient times the Xolos were often sacrificed and then buried with their owners to act as guide to the soul on its journey to the underworld. These dogs were considered a great delicacy, and were consumed for sacrificial ceremonies – including marriages and funerals.
The name Xoloitzcuintli (pronounced “sho-low-itz-queent-li”) is derived from the name of the Aztec god Xolotl and Itzcuintli, the Aztec word for dog. (Xolo owners are frequently stopped and find themselves explaining not just the breed – but teaching people how to pronounce the name!) Indigenous peoples believed them to have healing powers and they were thought to bring relief from a vast variety of ailments. That belief still survives today in the rural parts of Mexico. One of the reasons being that they feel warm to the touch – and can actually act as a “hot water bottle”.”
“Gene mutations happen accidentally,” Boyko said. “They happen randomly. Then they are perpetuated because they serve a purpose evolutionarily. Because dogs are domesticated and people can selectively breed them and selectively protect them and provision them, you’ll get mutations like this that really would disappear rather quickly if it happened in a wild population. If you had a hairless Wolf that didn’t have good teeth, it wouldn’t last long. It’s not going to survive to adulthood and reproduce.”
