Denver's busiest vet returns in a new clinic with more patients than ever before; Dr. Jeff fights to help a dog walk again; Dr. Amy operates on a cat with a strange appetite; the team heads out to a sanctuary to help an injured tiger.

An owner drives nine hours to the clinic hoping Dr. Jeff can save her dog's leg. Jeff and his team head to a wildlife sanctuary to treat a pack of wolves. And when a kitten with a deformed leg needs treatment, Dr. Baier steps up to the plate.
