The Vet Volunteers are a group of ordinary kids with a special job--helping animals at a veterinary clinic From saving puppies in Pennsylvania to helping manatees in Florida, the Vet Volunteers work with all kinds of animals and have great times with their best friends.

New Beginnings
Meet Jules and Josh, the new twins in town While Josh adapts quickly to Ambler, Jules accidentally makes an enemy of Maggie. Hoping a pet will help her feel better, Jules adopts the class rabbit, Chewie, but things go downhill when there are complications with Chewie's spay surgery. With Dr. Mac out on a call, it's up to Jules to work with Maggie to help the rabbit--and maybe even prove that she and Josh are worthy of becoming Vet Volunteers.

Acting Out
Zoe is back in Ambler after living with her mom in Los Angeles, and she doesn't know what to feel about it. It's fun to be back with the Vet Volunteers, but Zoe misses her mom, who is filming a movie in Canada. Meanwhile, there seems to be a rash of animals being poisoned by antifreeze across the town, and Zoe fears that David's new adopted cat, Rover, might be one of them. So the gang works to raise awareness about antifreeze poisoning, and Zoe's mom has a special surprise in store for everyone.

Helping Hands
Jules and Josh are so excited when their parents hire ponies to attract customers to their sidewalk sale. But the Vet Volunteers notice that the ponies don't seem to be very healthy, and after an examination, they learn that the handler, Gus, has been mistreating them. Can the Vet Volunteers help the ponies get well and find a better life for them?
