Average stay in the hospital for the more than 50,000 animals that UC Davis treats every year is less than a week. It is a rare occurrence for an animal to be hospitalized for four months, but two alpacas that the UC Davis veterinary hospital’s Large Animal Clinic treated this fall did just that. Apple Jack and Jasper became household names at the hospital, being seen by nearly every fourth-year veterinary student who had a large animal rotation. The students and technicians even decorated their barn stall for the holidays.
