Is that the same one that peed on the electric fence? I won't use a choke chain at all. Just MO. I've seen to many damaged tracheas and hung dogs with them. I've seen them fall right off when loose too. I use a chain martingale though, same premise, but it only tightens so far and can't fall off. I'll use a remote trainer too (E-collar) to reinforce off lead what they have already learned on lead. I train some ranch dogs that will rarely be on a leash. E collar is what I use for boundary training, livestock aversion and COME from anywhere.
OMG YEs same idiot Worse part is watch him and his boy see who got the biggest pair by holding the collar and letting the other "punch the button" They start at level 1 and work their way up. Sort of like playing chicken or bloodly knuckles only with electricity. Evidently it happens in the "best of family's and they breed
