Overview: The pets of Central Michigan are in a jam, and it's up to PVS to get them unstuck. Dr. Pol plucks porcupine quills from a Mastiff's nose. Dr. Nicole pulls three feet of string from a cat, and Dr. Lisa unhooks a dog from a fishhook. An emergency case sends Dr. Pol out on a farm call to treat a horse with choke, while Dr. Brenda has her hands full with pregnancy checks on a herd of rowdy cows.
