What breed is the Tanner family's dog Comet?

Comet, the Tanner family’s dog, is a golden retriever.

Comet enters Full House in the season-three episode “And They Call It Puppy Love.” His mother, Minnie, is a golden retriever who wanders into the Tanner family’s backyard and gives birth to puppies. The family keeps one of the puppies and names him Comet.

Comet becomes especially associated with Michelle, who forms a strong bond with him as he grows. He appears in storylines involving the family’s responsibilities, Michelle’s attachment to him, and the complications of caring for a much larger dog than the puppy they first brought home.

The dog who portrayed Comet was Buddy, a trained golden retriever who later became famous as Air Bud. That real-life connection can cause confusion, but the breed answer concerns Comet’s character in the show. Fuller House later introduces Comet’s descendant, Comet Jr. Jr., and another dog named Cosmo.
