The Blue Dog Safety Video

The Blue Dog Safety Video is the collective name for a duology of short films written and directed by Les Drew for the National Film Board of Canada. They consist of Every Dog's Guide to Complete Home Safety (released in 1986) and Every Dog's Guide to the Playground (released in 1991). They follow a blue dog named Wally trying to protect his owners from their own carelessness.

Every Dog's Guide to the Playground
The mother is pregnant throughout the short. She goes into labor at the end, and gives birth behind closed doors. The dog and father are pelted with babies from the delivery room, making it unclear which or how many are theirs.
