Dr. Oakley starts on Chichagof Island, where she does a herd check on a group of cattle and treats an enormous bull with a split hoof. Back in Haines, the Oakley family's own pet pug is having chronic health issues, including serious trouble breathing. The team has to get to the bottom of her illness to give her the help she needs. Finally, Dr. Oakley heads to the Alaska Wildlife Conservation Center to treat an aging elk and a beloved black bear.
