When you're a pet, you must go to the vet. Like humans, pets need to eat well and get exercise in order to stay healthy. Caillou and Gilbert learn that sometimes you even have to rescue your pet. Poor Gilbert gets stuck in a tree, but once he is safe and sound Caillou gets a ride in the fire truck and even gets a tour of the station house. As the family pet, Gilbert puts up with a lot, including playing dress-up, but in the end most of what he gets is love. Even Rexy enjoys the attention that comes with being Gilbert's pet.
