Syringomyelia in Cavaliers and Beyond: What Every Breeder Needs to Know
Dr. Marty Greer joins Laura Reeves to answer a listener question and break down one of the most serious and underdiagnosed neurological conditions affecting small breed dogs.
If you’ve never heard of syringomyelia, you’re not alone — but if you breed Cavalier King Charles Spaniels, Brussels Griffons, Pomeranians or other small brachycephalic breeds, this episode could change how you think about your breeding program.
Dr. Marty Greer walks Laura through the difference between Chiari-like malformation and syringomyelia (SM), two conditions that often get lumped together but aren’t quite the same thing. The short version: when the skull is too small for the cerebellum, fluid circulation gets disrupted and painful pockets of fluid can form along the spinal cord. The result is a dog in chronic, often invisible pain.
The symptoms are easy to miss. Phantom scratching near the neck, sleeping with the head elevated, flinching when picked up or eating from a floor-level bowl — all of these can look like something minor. In Cavaliers especially, an ear condition with overlapping symptoms makes diagnosis even trickier. Only an MRI gives you a definitive answer, and that’s where things get complicated fast.
MRIs run anywhere from $1,500 to $3,000. Dogs need to be fully anesthetized. Cavaliers aren’t the easiest anesthetic candidates for a variety of reasons. And even after all that investment, the genetics are multifactorial and polygenetic, meaning two “clear” dogs can still produce affected offspring.
The numbers are sobering. When screening efforts launched in the U.S., the breed incidence was estimated at 60 to 80 percent. Careful screening cut that roughly in half — but that still leaves the breed sitting around 35 to 40 percent affected, and only a fraction of dogs are ever screened.
Treatment options exist but aren’t encouraging. Surgical intervention has a relapse rate of over 50 percent. Long-term management means gabapentin, steroids and other medications for the life of the dog. It’s a heavy burden for dogs and owners alike.
So what can breeders actually do right now? Marty and Laura make the case for breeding normal to normal as consistently as possible, tracking health outcomes across generations and pushing for group MRI clinics to bring costs down through volume. One breeder they profile used to pack 8 to 10 dogs into a vehicle and drive to Canada just to get affordable scans. That’s dedication — but it shouldn’t be the only option.
If you have access to an underutilized MRI machine or you’re actively doing DNA research on this condition, Laura wants to hear from you. This is exactly the kind of problem the Pure Dog Talk community wants to tackle. Email: Laura@puredogtalk.com

517 — Veterinarian: Brachycephalic Does NOT Equal Unhealthy
Veterinary Insight on Why Brachycephalic Does NOT Equal Unhealthy
Dr. Maryanne Mack, DVM, breeder of top winning Boston Terriers, joins host Laura Reeves to discuss recent developments in Europe in regards to legislating the breeding of specific breeds.
“I went to vet school because I love purebred dogs,” Mack said. “I love their role as companions and I wanted to go to vet school really to focus on that role of the dog in our life… Just really wanting to work with people and their pets and breeders as well to just make healthier companions for all of us.

“I think that the fact that a lot of groups have started to associate having a short face with being unhealthy is a really slippery slope that we don’t wanna go down. There’s a couple components of brachycephalic airway syndrome. Those are stenotic nares, or really tight nostrils, an elongated soft palate and a hypoplastic trachea. Those are sort of the three main issues that you see with brachycephalic airway syndrome.
“We don’t have any studies showing those are directly related to the length of the nose.
“The component that we really have to look for, that we know make the biggest difference in these dogs, is the elongated soft palate…
“That’s not related to how long the nose is, that’s related to different genes that are writing for the length of the soft palate. We see long soft palates in dogs with long noses. We see this in Labradors, we see this in mixed breed dogs. So, it’s not only a brachycephalic issue.
“I think it’s really important to note that these things can occur in any breed of dog. They do happen to occur more in brachycephalic dogs, but we don’t have concrete evidence that it’s directly related to the length of the nose.
“Most brachycephalic breeds, with the exception of some of the more mastiff types, these dogs were bred to be companions. That’s their job and they do that very, very, very well. Part of the reason we love them so much is that these brachycephalic facial features elicit almost an infantile like response to people. I think that focusing on the fact that these are companion dogs.
“These dogs are not out flushing birds, they’re not working dogs, they are meant to make people happy, sit on your lap. I absolutely believe that they should be able to do things like go on a little hike …. they should absolutely be able to do that and be able to breathe while they do that. But this is not a dog that’s out herding sheep in the summer. I think keeping that in perspective is really important.
“I think we need to focus, as preservation breeders, on doing a little bit of a better job on selecting breeding stock and producing healthier versions of every breed. But for brachycephalic, specifically, we all know that there are some dogs out there that are not good breathers and that happens.
“I think the hard part as a breeder is to say ‘OK this dog might be beautiful, this dog might have a great top line and this has great movement but he cannot breathe and I should probably put him in a companion home where he won’t be bred.’ That’s a really, really hard decision to make, but I think as we move forward, especially in this new culture and climate, we have to make more of those decisions.
Preservation Breeders are the Solution
“We as preservation breeders are actually the solution. We are the solution to this problem. If we work together to breed healthier dogs and if we work together to breed more of these dogs… I can’t tell you how many of my clients come in with a puppy mill puppy and they say ‘Well Dr. Mack, you told us some great breeders but we didn’t wanna wait for three years, so we ordered this one online and picked it up at the airport and here he is.’
“It breaks my heart because we as preservation breeders, if we had more available dogs that were well bred, people would buy them and they would love them. Vilifying people that breed more than one to two liters a year or whatever number you’ve decided is too many I think is detrimental to all of us.
“I first posted a statement in the beginning of 2020 basically saying I’m a veterinarian, I breed these dogs and it can be done right. These dogs are not inherently unhealthy. I received enormous backlash basically saying this veterinarian shouldn’t be a veterinarian, how can any veterinarian promote the breeding of brachycephalic dogs. It went so far as to contact my place of work, contacting me personally. I had to take my website down. I had to make everything private. I had to tell people who had wanted me to be an advocate for this I can’t do it right now because they’re coming for me.
“In the veterinary community I get backlash like ‘how can you breed these dogs.’ Oftentimes these people, once they meet my dogs and realize they can breathe and they’re healthy and they look great, they realize that we see a disproportionate number of unhealthy dogs just by the nature being veterinarians.
“I’ve actually done a little self-study where a dog comes to see me and I always find out where the dog came from. Then I make a note what issues does this dog have. About 95% of brachycephalic dogs I see that are bad breathers are from a pet store, a puppy mill or rescue. That is just the fact that I’ve gotten over six years of being a veterinarian, that these dogs are often the ones that they ordered online.”
