The Functional Breeding Podcast

We revisit our conversation with Dr. Danika Bannasch about chondrodystrophy (CDDY), the genetic mutation associated with it, and its relationship to intervertebral disc disease. Danika explores what genetic testing can—and cannot—tell breeders, and how to think about genetic risk while making thoughtful decisions for both individual dogs and the broader population. Support the podcast and the work...

It's a conversation that continues to ch...

In this episode, interim host Jess Sedivy Gunderson welcomes back Dr. Rowena Packer to discuss new research examining how puppies' earliest experiences—including age at sale, seeing the mother, and sourcing decisions—can impact health outcomes later in life. Together, they explore what the findings mean for breeders, puppy buyers, and the future of canine welfare. If you'd like to support the podc...

In part two of this conversation, Jess Sedivy Gunderson continues her discussion with Jane Lindquist, diving into Jane’s newer work around weaning, early nutrition, and the puppy gut microbiome.

In this episode from our archive, we revisit an important conversation between Perry and Dr. Jane Ladlow, VetMB, DipECVS, MRCVS, on brachycephalic obstructive airway syndrome (BOAS), functional health, and the future of brachycephalic breeds. Their discussion explores the real-world welfare impacts of extreme conformation, the challenges of balancing breed type with health, and what meaningful cha...

Before stepping in as interim host, Jess Sedivy Gunderson joins Sarah Stremming (Cog-Dog Radio) alongside Xan Latta to share the story behind the Flatcoat Conservation Project. From the cancer crisis in Flat-Coated Retrievers to the promise of genetic rescue, this episode explores what happens when breeders choose dogs over tradition—and what that could mean for the breed’s future.  If you'd like...

This episode, I am being interviewed by Sarah Stremming about a recent scientific article about the genetics of behavior in herding breeds and specifically in border collies. I talk about the study's methods and what it all means, and Sarah grounds it in her deep practical experience with herding dogs. Sarah has been on the podcast so many times that she hardly needs an introduction but for new li...

This week I'm talking to Dr Laura Sharkey, dog trainer turned dog breeder, who runs the Bosun Dog Project. This project produces lovely mixed breed dogs who are bred to fit well into homes as companions. This episode was actually recorded in person with me and Laura in the same room. We started talking about what we would talk about and then I realized she had already said some really interesting...

This week I'm talking with Dr Micah Halpern, a geneticist who has worked with many species including zoo animal population health, and is currently the pricipal scientist and owner of GenSol Diagnostics. Micah and I got nerdy about genetic testing for canine health and other traits - what are some of the different technologies involved, and how do we think about what "accurate" means in terms of r...

Dr. Hille Fieten is veterinary researcher and clinician specializing in internal medicine. She is is the coordinator of the Center for Expertise in Genetics and Veterinary Medicine at Utrecht University. I have received multiple requests to talk to her about her research into the genetics of copper toxicity in dogs. Some of her research has been used for new genetic tests, and the dog loving commu...

A new paper, "The prevalence of behavior problems in dogs in the United States," is getting people upset - is it true that 99.78% of owners think their dog has a behavior problem? That's not actually what the paper says, and I'm here with Sarah Stremming of Cog Dog Radio for a joint episode. We talk through the paper's findings and what it means for those of us trying to make the world a better pl...

Dr. Paula Boyden is the veterinary director of Dogs Trust UK, an animal welfare organization that, among many other things, investigates illegal importation of animals to the UK.
