It's mating season in the Yukon which means Dr. Oakley is busier than ever. She gets her hands a little dirty first to diagnose Priscilla, a cow who can't seem to get pregnant. Then, she gets a call from the Yukon Wildlife Preserve to help with a tricky case of a young caribou bull with growths on his nose. Then it's off to the next appointment, but this one is different. Mating season isn't in the cards for Dr. Oakley's dog, Daisy Mae Lover-Pants, and the time has come for her to get spayed.
