So, the Harbaugh brothers are coaching against each other in Super Bowl XLVII on Sunday? Big woof. In Puppy Bowl IX, EIGHT sets of siblings are facing off on the gridiron, including miniature pinscher brothers Re Re, Frances, and Winston, along with sister Agatha. Plus, all dogs have tested negative for deer-antler spray.

This year’s installment of the annual competition of cuteness, which airs Sunday at 3 p.m. on Animal Planet, will feature 63 young pooches scampering across a tiny football field. They will be cheered on by nine hedgehog cheerleaders, and entertained by a 21-kitten halftime show. Did you know: More than 250 puppy pee pads were used in the making of this spectacle? (Also, there was one humping incident.)

Click on these two preview videos to get a taste of the action. And as a bonus, here’s a photo of Brian Williams (who shot a Puppy Bowl segment for NBC Nightly News), his daughter Allison (star of Girls), and Pearl (potential star of Puppy Bowl IX) huddling on the set.
