I was wondering what I could use on SammyJ when we went out in public which we dont much, but hes really going to hurt himself someday by pulling to hard, I have to keep a really short leash to keep him trained in..I dont use a leash at home unless we leave the property, so theres no problem there, but when we went to the pet store my word he had me worried, afraid of him hurting himself that prog collar might be good..
