Even after we go for a long walk, and he eats his food and drinks his water, he will stand there wagging his tail and making a weird squeaky noise that sort of sounds like a whistle. His breed is a Pitbull.Rottweiler.Shepherd X. Im wondering if its because hes spoiled because when I ask him, What do u want? he darts his eyes towards the fridge. Oh, and hes not neutered, and hes 4.
