i have 2 Newfoundlands a male and a female. Both have been through clicker training. They did not cover this I have tried forcing them down with a stern NO. I have tried turning my back to them. They jump on my back. I was told to knee them in the chest or step on their hind feet. That doesn't sound correct to me. I am only 5'5" so they are looking into my face. I need help please.
