In the past, we tried using various types of collars. None of them were effective. Our dog would always try to pull away and then end up choking himself. When we switched to a prong collar, all of our issues went away. He doesn’t try to pull away and is easy to control. The prong collar doesn’t choke - since it tightens evenly all the way around when a dog tries to do his “own thing”. Oh, and by the way, our dog is a 150lb Newfoundland :-)
