The year's biggest sporting event is finally here... Animal Planet's Puppy Bowl!

An honored tradition, the Puppy Bowl features 50-plus dogs up for adoption as they sniff, play, pee and snooze their way into the end zone. And while NBC's Super Bowl may be touting the big Katy Perry halftime show, Animal Planet has nabbed their own big star to headline: Katty Furry!

Animal Planet's Puppy Bowl XI airs Sunday at 3 p.m. ET.
