My border collie black lab mix has been behaving poorly. whenever i take him for a walk, he jumps bites, nips at my clothes etc. Also i do not like taking a bike ride with him because he is part border collie he trys to "herd" me and i am afraid i will run him over. We cannot afford obedience classes either. I do tell him OFF and things in a deep voice but he doesn't seem to get it. Even if i ignore him when he mis behaves, he just jumps or bites more. Do not judge me. Please just help or give me some tips.
