Please someone help me...we were doing so good training with loose leash the last week. I just tried to take Jake out for a walk and he had two things in his mouth the entire time, either the leash or my legs. He ripped my pants, socks and skin. If he let go of me he bit and pulled the leash so we couldn't move. I am in tears as I try to type this. I LOST IT! Screamed, yelled jerked him around a few times on the leash....all the things you shouldn't do. I am at the end of my rope...I can't take much more...how long is this going to last?
