a year ago I was using the semi choke collar, advised the canine center. J 'had enough to cough my dog and it did not prevent him to shoot sometimes. With this harness, it still takes a little but when I pull on the leash it brings it back to me, which forces her to look at me. She walks to the best shot in the foot. In canine center, of course they wondered what it was this harness but I do not care that works. The only drawback is that the leash spends time in the dog's paw when the leash is loose.
