Animal Planet has made some changes to this year’s “Puppy Bowl” But don’t fret, the adjustments are part of an effort to turn the cuteness factor up to 11. In addition to the regular kitty halftime show, “Puppy Bowl VII” will feature a piggy pep squad; a new smaller referee (so he can be closer to the action); Meep, the tweeting bird; and the largest number of puppies to ever compete: 67. Are you ready for a total heart meltdown? Check out some preview pics of the action below. “Puppy Bowl VII” kicks off this Sunday, Feb. 5 at 3/2c on Animal Planet.
