I have something to add that I didn't say in my post. I would never use this on my dogs because they are too small. I don't think they even make them for small dogs, but if they did I wouldn't use them. Like I said, I don't think they are cruel if used properly. Grizz is 145lbs and he has thick hair. I doubt he feels too much when he pulls. Sylvia is 17lbs and Harley is 22 lbs. I think using this on dogs that size would be wrong. I can control a 22 lb dog safely, but as I said, a 145lb dog is hard for anyone to handle. There are other ways to control a small dog versus a very large dog.

Anyway, the thing must work because Grizz walks well on a leash and he doesn’t need the collar anymore.
