Avsnitt 4

Family members rush their chihuahua, Darcy, to the clinic after it is hit by a car. For 18-year-old TaJournée, who is autistic, the dog is a lifeline, and Noel must use pins, nuts and bolts to reconstruct the broken pieces of its crushed pelvis . Meanwhile, the vet finds himself in a tricky situation while performing replacement surgery on a seven-year-old spaniel with hip problems, and a Winchester Prison sniffer dog that is lame in both elbows is brought to the surgery.
