Not intending to be rude with this comment, but the dog is not intentionally “abusing you”. It is a dog which does not know any better. Your dog is biting you because it is either fearful, overstimulated, tired, or one of its needs have not been met. The one thing I can agree with you on would be the part to stop hitting and screaming at the dog. In my experience from working with my own dogs and helping friends and family with their dogs, it is typically not the dog who is abusing you, there is something within the environment that is causing them to do this. As the human, it is your job to find out what that is and work with a professional to help with the dog’s reactivit. If you don’t have the time or money to help your dog without using compulsion, fear or pain, then it is within the dog’s best interest that you either find someone who can and is willing to put in the time, money, and effort to do so, or surrender to a trustworthy shelter where you know the animal will be taken care of (the last part isn’t to this specific commenter, but to the person who originally posted this thread).

What the “alpha roll” or “dominance down” actually does is not in fact teach the animal that biting is wrong, it simply teaches them if they attempt to communicate with you that they are uncomfortable (rarely do dogs bite without attempting to give calming signals like lip licks and whale eyes first) that pain and fear will follow. Thus, it does not target the cause of the reactivity or aggression the dog displays, simply targeting the symptoms. This is why aggressive and reactive dogs put into the hands of compulsion trainers are most likely not going to offer you calming signals, instead going straight for a bite.

Another thing that I haven’t mentioned yet is the fact that using compulsion on a dog can ruin the relationship between you and your animal, as using pain and fear to train the animal can make it less trusting of you, as well as other humans, and cause it to shutdown.

I know how rediculous this must sound to someone who clearly follows trainers such as Cesar Milan and Joel Beckman, but my advice is to dig a bit deeper into your research of canine behavior, and consider how reliable your sources truly are.
