The Incredible Dr. Pol

As the clinic's 30th anniversary approaches, the Pols plan an old-fashioned pig roast after extracting a mouthful of porcupine needles from a dog and inseminating a cow, of course.

Dr Pol and his son Charles attend to a terrier with a mystery leg problem, and two cows with internal ailments.

Dr. Pol needs to take blood samples from a flock of sheep to test for Ovine Progressive Pneumonia, a progressive, incurable and highly contagious disease.

Two goats are among the patients, one may have been blinded when a horse kicked it in the head.

A dog really does eat homework; a horse rapidly loses weight; a tornado warning forces all the animals and staff into the basement.

Spring fever strikes as the team deal with triple-booked appointments and Dr Brenda takes on a cow that weighs a ton.
