The Docs at Critter Fixer help a koi fish with skin cancer, clean up a rescued bunny that has some pets of its own and perform a second ACL surgery on a Doberman. Plus, Dr. Hodges and Dr. Ferguson teach inner-city kids how to check cows for pregnancy, put their dental skills to the test when a dog comes in with a tooth abscess and tag-team the banding of some young brother goats!
