Welcome to season 2 of the Biologica Podcast! Join Dr. Susan and Dr. Christine Calder as we explore cats, how they see the world and their lives in our homes, and when/why things go wrong. We’ll explore cat aggression, stress and conflict in multi-cat homes, and other cat behavior issues, but also how they connect to the natural behaviors in wild cats they are related to. We’ll also explore things we can do to help. Learn about the “tiny tigers” in your home, and how to make the home setting a more healthy and happy space for them.

A donation was made to the Animal Refuge League of Greater Portland (and in honor of all of the other shelter and rescue organizations) in thanks for all their work going above and beyond to help the Pandemic Puppies - and the lovable but sometimes challenging adult dogs they’ve grown into.
Note - Pippin was named Friendly when first adopted, and so you’ll hear him called that some in this episode (from before he was renamed).
Also- I just want to acknowledge: sometimes a dog can struggle with behavioral issues despite the humans in its life "doing everything right" - when that is the case, working with a trainer or behaviorist and your veterinarian are excellent options.

Dr. Susan is welcoming a new puppy, Pippin, into her home. Pippin is a rescue boston terrier, and inspired an episode on the "smushed-face" (brachycephalic) breeds.
Dr. Mark Hanks and the host discuss brachycephalic (short‑nosed) dogs: their unique anatomy, medical issues and care, and breeding implications, with practical advice for owners on when to seek veterinary care.
The episode also delves into the increasing popularity of breeds like english bulldogs and frenchies, and the controversies and debates this has spawned. Finally, the issue will be looked at through both scientific and poetic lenses. Come meet Pippin and find out more about these beloved but complex dogs - why they have such special needs and spark such debate!
