Dogs love to be Pigs, it's just the way things are. Nobody knows why but it sure is funny. Dogs wish they had a spiral, curly tail and flipped pink ears. Dogs will immediately go crazy for this hilarious Dog Costume because it's their true nature. The medium size should fit a healthy dog comparable to a Cocker Spaniel. The large size will fit a large breed dog like a Labrador or Pit Bull. Let your Dog live out their life-long fantasy of being a powerful Piglet with a taste for bones and squeaky toys..
