I had a boxer that would only be bitchy with others when they scolded her. I raised my pits to know what a spray bottle means. I just grab it and the hunch down like I beat them to death people can’t believe it. If I have learned anything with my pits is you have to have a firm voice when commanding them. My mom has raised several breeds of dogs and they all obeayed her but her 9 month old female pit doesn’t respond to a word she says and loves water so the spray bottle doesn’t work on her. She only listens to me or my dad. It is truley in the tone of your voice and making sure that you never show fear or back down to them when they at like that. You are the boss and they have to know that.
