dog

You found a dog, and you let him in your house. You took care of him and eventually he trusts you. He likes you and is almost like, your best friend. Anyways, your friend (it could be anyone even a toaster) didn't like the dog and is trying to harass your dog by throwing rocks at him. What do you do? protect your dog? Oh yeah, your dog you can name him anything, but he's playful and energetic, the age is up to you, hes just very young though.
