Puppy Bowl XXI is the 21st anniversary of arguably the cutest pre-Super Bowl event. The "competition" each year has two teams of dogs from shelters and rescues around the world facing off in a football game. The event encourages viewers to consider adopting a dog from an animal shelter or rescue rather than a breeder.

If you tune into the “Puppy Bowl” on Sunday, you’ll likely see a key person’s influence — even if you don’t actually see her.
