What would be your suggestion on a collar or harness for my dog? Quick background - though I tend to ramble:
Colt is about 50-55 lbs, and very strong. I don't know if he is DA having taken him from a shelter, but I treat it as he is because I don't know. He reacts VERY strongly to other dogs barking at him, rabbits, squirrels, birds, etc. Neighbors have a lot of smaller, yippy dogs that bark like crazy through their windows and fences and Colt never barks or growls, but he pulls SO hard (and mouth chatters) that he can drag my 275 lb boyfriend like it's nothing. Colt may just want to play, but my feeling is that he would be aggressive - so I don't let him near anything. It's my responsibility to keep him out of trouble, right?
He currently wears a martingale collar with his tags unless he is being walked, and then I change to a prong collar. It doesn't seem to slow his pull much, but it's better than him choking himself until he hurts his throat on a regular choke chain. We are working very hard on his walking obedience and when he starts pulling I stop and we don't walk again until he is calm again (makes for very long walks when the neighbors dogs have NO manners at all).
Would using a harness just give him more power in his pull? Our vet suggested using one of those muzzle/head collars, but there is no way it will work with him - I know him too well. I worry that he is going to damage his neck & throat pulling the way he does.
