After endless bullying by the much smaller cats, dogs are determined to no longer be the butt of their jokes. So how can the friendliest animals on the planet get even? Apparently by sticking their butts in cat's faces.
So the next time you need a cat sitter while you're away, we recommend finding a professional. Otherwise your dog may take the job a bit too literally. Watch our compilation above to see for yourself.
NOTE: All of the dogs we found doing this seemed playful and the cats appeared unharmed. However, please make sure your dog never accidentally takes things too far.
