Who's side are you on?

If your Dad does not actually hate the Dog, he will get over it. You should not have pestered your Dad so much, every member of a family needs to agree on having a dog. You were wrong to do this, and if your Dad is taking it out on the dog he is wrong. I'm on the side of the dog, for the sake of the dog I am hoping the you can both grow up and make it work. If you can't you need to return the dog to the rescue you got the dog from so that it can have a happy home.
