Misunderstanding!
I dont't mean grabbing, squeezing, pushing or anything like it. I simply hold the dogs muzzle, just in front of the eyes, with an open hand for a second or two. My fingers are
not wrapped around the muzzle, it's just my open thumb and forefinger on top of their muzzle. I don't fight the dog or force any position on them, in fact there is less pressure than when I hold their muzzle for grooming. I just meant that I use a very slight pressure that may move their nose down and inch. I haven't used it in ages, the last time was when my puppies were in a bitey stage, and they had persisted in biting after a yelp, ignore and "no"
It does not make them handshy at all. it's totally non-violent. Believe me, I would never ever do anything harsh or frightening to a dog. Way back in the "Dark Ages of dog training", the Alpha Wolf/pack theory/dominance methods, I am ashamed to say I did the "Alpha roll" a couple of times on one of my Dobermans. What an awful thing to do! I have never forgiven myself for that, and for other serious training mistakes I have made.
I would never post or suggest anything that could backfire and harm the dog, or the relationship between dog and owner.
