The Functional Breeding Podcast

We're revisiting one of our favorite conversations with Dr. Mary Peaslee, exploring what functional, sustainable breeding looks like in practice. Drawing on the English Shepherd community's approach to genetic diversity, open registries, and functional breed standards, Mary shares thoughtful insights into balancing health, predictability, and collaboration. It's a conversation that continues to challenge us to think beyond individual dogs and toward the long-term future of their breeds.

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.

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.

The episode explores how breeders are beginning to think more deeply about gut health during developmental periods, the role of maternal influence and early diet, and how weaning practices may shape long-term health and resilience. The conversation also emphasizes that there is no single “perfect” approach to raising puppies, and that breeders across feeding philosophies can benefit from understanding the emerging science in this area.

Note: This episode focuses on weaning strategies and the puppy microbiome. However, discussion of diet is closely connected to any discussion of the microbiome. The Functional Dog Collaborative does not endorse a single feeding approach; listeners are encouraged to evaluate options based on current evidence, veterinary guidance, and their individual program goals.

In this two-part conversation, Jess Sedivy Gunderson sits down with Jane Lindquist to revisit and expand on one of the Functional Breeding Podcast’s most downloaded episodes.

Together, they explore what has evolved in puppy raising over the past several years, including socialization, resilience, developmental periods, breeder observation skills, and how the pandemic shaped conversations around raising puppies. Jess and Jane also discuss what has stayed the same, what has shifted, and why thoughtful puppy raising continues to require flexibility, curiosity, and adaptation as new science emerges.

Part 2 of the conversation drops a few weeks later and will focus on Jane’s newer work around weaning and the puppy 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 change could look like moving forward.

Though this episode originally aired in 2024, the conversation remains deeply relevant for breeders, owners, veterinarians, and anyone interested in functional health and ethical dog breeding.

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.

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 listeners, she is an internationally known dog behavior consultant and speaker. You can learn more about her at sarahstremming.com and I encourage you to check out her podcast, cog dog radio, where this episode is being jointly released.

On a personal note I want to let you all know that while I haven't been releasing episodes, this podcast has been very much on my mind. I continue to suffer from chronic fatigue which makes this kind of effort really difficult for me - after recording this episode I was unable to work for the rest of the day. I'm improving but it's very slow going. I am deeply grateful to those on Patreon who continue to support the podcast during this hiatus - that support goes straight to the Functional Dog Collaborative and is much needed and appreciated.

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 stuff, so I hit record and prompted her to start over, and away we went, talking about some of the fascinating discoveries she's made with her analytical brain while raising many litters of foster puppies and five litters of Bosun puppies! If you want to know more about the Bosun Dog Project, you can go to bosundogproject.com.

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 results?

I've had a long break from recording podcast episodes and I'm coming back gradually. My series of unfortunate injuries seem to be coalescing into chronic pain that makes working difficult. The Functional Dog Collaborative is a high priority for me but sometimes I do have to take a break from this podcast while I recover a bit, and this was one of those times. I hope to have episodes coming out more regularly, but also a bit more slowly than previously, for a while, while I improve and ramp them back up. I appreciate your patience.

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 community is asking how to interpret these tests. Buckle up for a lot of information coming at you!
