Dr. Ian Dunbar's iWoof podcast
Great not only because they’re called iWoof Podcasts, but because there are five whole seasons of them, and they pretty much cover everything.
Dr. Dunbar is a veterinarian who is incredibly knowledgeable about both the behavior and medical side. His podcast is frank, science-based, and funny.
Each episode is different from the last, and that’s what makes it so refreshing—one week it’s all about socialization, and the next it’s about Sarah Palin praising her son for stepping on their dog.
