PetSmart TV Spot, 'A Happy Belly' Song by Queen

To the tune of Queen's "You're My Best Friend," a brown and white dog lives it up. She is fed, plays ball outside, lays on the couch with a boy as he reads a book and gets lots of belly rubs. PetSmart says the key to a happy belly is good nutrition and digestion and suggests the Limited Ingredients Diet dog food line from Natural Balance.
