Strawberry Jam Disease is a f disease that Olivia invented when she was pretending to be a veterinarian in Olivia Becomes a Vet. Perry, Olivia's pet dog, supposedly was infected with this particular disease when strawberry jam smudged on his fur, leaving pink, strawberry-scented, stains on him. Olivia thought that he was sick, so she tried to care for him. The jam got on the couch when Perry jumped on it, and Olivia presumed the sickness was contagious  and fatal.
