My 7 year old dog has lost his mind. He wants in and out every 10 minutes. He keeps trying to show dominance to anyone who enters are home. He has started barking at everything. He has become hard headed about listening.

We have tried several things to get him to stop this behavior. We don't let him show dominance and stop it as soon as he starts. We hold tight until he listens when we tell him to sit or stay or whatever. But I am at a loss on the going outside 50 times between when we get home and when we go to bed. All he does is bark...but if we don't let him out he freaks out.
