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.

The Super Bowl is happening this weekend, and if you also enjoy sporting events with tail-wagging, toy-tugging and miniature limbs, you can watch good boys and girls face off in the 21st Puppy Bowl. Puppy Bowl XXI will showcase 142 rescue puppies from 80 shelters -- the biggest canine cohort yet -- before the Super Bowl airs at 6:30 p.

Warner Bro’s Puppy Bowl XXI is an annual television program similar to the American football championship, the Super Bowl, but featuring puppy players. It is returning for its 21st year on Sunday, February 9 and will feature 142 rescue puppies from 80 shelters across 40 states and two countries.

Clear your (and your pet's) schedules—the 21st Annual Puppy Bowl (Puppy Bowl XXI) is this weekend. This yearly sporting event broadcasted by Animal Planet is not only adorable, but it historically raises awareness for shelter animals in need of adoption.
