It is sink or swim as Dr. K tries to solve mobility issues for two goldfish. A severe macaw is brought in with a serious bite wound to the foot, caused by a bigger bird. A rabbit presents with a large amount of fluid in the abdomen and the exploratory surgery reveals a shocking result. Dr. K treats a tiny yellow-bellied slider that may have pneumonia, while Dr. Thielen treats a ferret with a large tumor on her tail.

Dr. K and her staff are faced with many difficult cases this week. A pot-bellied pig comes into the clinic with an obstruction in her stomach that leads to emergency surgery. A salomon boa presents with a bad respiratory infection that can lead to death if not treated properly. A black swan is rushed in after being run over by a car. The swan must have surgery but may not survive due to the severity of the injury. Dr. Thielen sadly has to diagnose a 5-year-old Ferret with insulinoma, which is a fatal pancreatic cancer that occurs in over 60 percent of the species. And an egg-bound turtle must lay 12 eggs to avoid surgery.

Dr. K helps a bunny with a bad eye and a bleeding Sumo Dragon. Later, she treats a macaw with a mass and a marmoset going into premature labor.
