Hi, I'm watching a large pitbull, and it seems to me that the owner doesn't take correct care of him. His food is stale, he refuses to eat it, but destroys my puppy's food like he's never seen a meal. He acts like he's being abused/beaten, any time i pick anything up off a counter or any solid object at all, he flinches, and runs away. Granted, he's deaf, but a 100lb pitbull should not be acting like a gatorade bottle scares him. He also won't eat out of his bowl, he flinches when i put it down, he'll only eat out of my fiancee's hands. His owner has claimed to have had him since he was a newborn puppy, so he's had no other owners, he's 2.5 years old.
