Okay, take a deep breath, and know the situation is not hopeless. You have been lead down a lot of wrong paths here, but the pup is still young, and it is not hopeless. I would completely ditch the "pinch" collar - he is a bulldog, that is not going to give him any pause one bit. I am sorry that trainer still believes that "alpha" stuff, but hopefully he/she has not had you do anything like hold him down or stuff like that.

I would absolutely start with a NILIF program with him. This is "nothing in life is free." Start today. It is not about physical strength, it is about getting the dog to realize you (and your husband) are the source of all good things, and without you, life is no fun.

Does he wear a collar or harness all the time? attach a leash to it, and keep him on leash always for now. It's annoying, but the effort will be worth it in the long run.

Who feeds him?

Who walks him?

Is is more interested in treats or toys?

Sorry so many questions, but we want to help!
