Don't care about Chiefs vs. Eagles? We tell you how to stream Team Fluff battle Team Ruff in Puppy Bowl XXI, the year's cutest gridiron competition.

They're the agility dogs at the Westminster Kennel Club show, which began Saturday by showcasing various dog sports. Dog folk often call Westminster the Super Bowl of dog shows, and the comparison might be especially fitting this year.

The Puppy Bowl is not just for the puppies' enjoyment and viewers' entertainment but also promotes pet adoption by featuring rescue dogs.
