This week we're getting nerdy about the genetics of dog coat color and type with two breeders, Ji Khalsa and Alicia Hobson. Ji has a Masters degree in Microbiology and Biochemistry and has done additional work in genetics. She has bred and trained working dogs most of her adult life. She is the founder of Midwoofery, a highly respected science-based educational resource for responsible dog breeders. Alicia is the founder of the Bearded Retriever Project, which is developing a breed based on poodles, Labrador retrievers, and golden retrievers with the goal of creating great companions. Both love teaching and are very good at it, and have a lot to teach about the genetics behind dog coats!

The Functional Breeding Podcast is about how to breed dogs for function and for health, behavioral and physical. It is brought to you by the Functional Dog Collaborative, an organization founded to support the ethical breeding of healthy, behaviorally sound dogs. The FDC's goals include providing educational, social, and technical resources to breeders of both purebred and mixed breed dogs, helping us all learn more about how to breed good companions who are fit for sports or work. You can find out more at functionalbreeding.org or at the Functional Breeding facebook group, which is a friendly and inclusive community.

Dan O'Neill, MVB, PhD, FRCVS is a veterinary epidemiologist who studies canine disorders that have an inherited component - what the rest of us might call "genetic diseases." He is the author of more than 95 papers, mostly on the prevalence and risk factors of disorders in dogs based on data drawn from VetCompass, the large scale veterinary database and research tool that he co-leads. Dan was awarded the Kennel Club Charitable Trust "International Canine Health Award" in 2021, and is passionate both about the health of purebred dogs and about saving breeds.

Danika Bannasch, DVM, PhD returns to the podcast to talk about the Dalmatian Outcross Project. Danika's laboratory found the genetic mutation that was targeted in this outcross, and she had a front row seat to the project's path to acceptance by the AKC and the Dalmatian Club of America. She is also herself a past breeder of Dalmatians. Danika walks us through the genetic, social, and practical implications of high uric acid in Dalmatians, why the outcross was necessary, how it worked, and which populations with different mutations could be helped today by a similar approach (spoiler - one of them is the population of dogs in breeds with high frequency of the chondrodystrophy mutation that we discussed in the previous episode).

Danika Bannasch, DVM, PhD is the owner of Pint, the famous UC Davis football tee retrieving dog. She also happens to run a genetics lab, also at UC Davis, where she studies the genetics of inherited diseases in dogs and other animals. She is known for her work associating genetic variants with a variety of traits including coat color and skull shape. On this episode we're talking about a genetic mutation that she discovered - known to genetic testing companies as CDDY - for a trait she feels passionately about, chondrodystrophy. Most of the dog world knows this mutation as "that risk gene that makes your dog more likely to get IVDD," but in this episode, Danika talks us through the difference between disc herniation and IVDD (intervertebral disc disease), noting that all dogs with CDDY have IVDD, and therefore disc degeneration, whether or not they actually herniate. I hope you learn as much from this discussion as I did.

Lisa Gunter, PhD, CBCC-KA is an Assistant Professor at Virginia Tech in the School of Animal Sciences and directs the Laboratory for Animal Behavior and Welfare. Lisa’s research explores the behavior and welfare of companion animals, specifically our interactions with them, as it relates to animal sheltering, behavioral issues, and training. Lisa combines a love of research with hands-on dog training skills. I wanted to have someone from the shelter world on the podcast because, depending on what you mean by "source," shelters are a source of dogs. Lisa and I talked about how shelters can best help dogs cope with the shelter experience and what the future of sheltering might look like.
For those interested in the Applied Animal Behavior and Welfare online MS program at Virginia Tech, where Lisa and Jessica both teach, check it out at https://www.cals.vt.edu/academic-programs/online/omals-program-virginia-tech.html.

Carolyn Kelly is a registered nurse with over 30 years of experience in human health including in labor and delivery, and in mental health. She also holds a Masters Degree in Nursing Leadership. She runs a mixed breed companion dog program, Old Mission Retrievers. Erica Pytlovany, KPA CTP, is an experienced behavioral consultant at WOOFS! Dog Training Center in Virginia. She runs the Boson Dog Project, a mixed breed companion dog program, with her wife, Laura Sharkey. I got together with Carolyn and Erica to talk about what companion personalities look like in dogs and why they focus their breeding programs on achieving them.
