I saw that link. I really don't have a problem with people holding animals by the scruff of their neck (reserved for growling/biting only) as long as it is positively not hurting them. I also use the alpha roll and it is also painless.
I guess I am a big softy because I see trainers use choke chains and prong collars. I just don't get it. A regular collar is bad enough which I am starting to really have second thoughts about even for big dogs. Ellie wears a harness because of collapsed trachea risk but who in the world came up with putting something around your dog's neck and choking them to make them listen?

Then people go a step further and jab prongs into their dog's neck. I just don't understand. If someone who reads this does this, I am not trying to offend anyone. I just don't see the sense in it. If I got a huge dog tomorrow, it would wear a harness, not a collar, and not a Genle Leader (don't even get me started on those). I must be in a mood today.
