Isn't it aweful. Chinook obedience instructor uses 'corrections'. She does not use choke or prong collars, but the corrections are scary too. I saw these pups (all between 7-15 months of age) cringe when the leash was yanked. Her 'correction' for barking was to take a firm hold on the wind pipe of the dog on the throat! Or if the dog was not listening she would take a good hold of the dog by its scruf and lift it off the ground and yell at it! I've never used corrections with Chinook. He is so eager to learn. The other people just stood there and some called me a 'show off' because Chinook was so well behaved and would listen so well - with NO corrections. If he made a mistake, that was fine, we just started over. At the last class, one lady asked: 'so what is the correction for when the dog does _________ at home?' I was amazed as how little these owners knew about training a dog and all they wanted was a 'quick', 'easy' 'solution' to the 'problem' - which really could have been dealt with in a positive way - hey news flash! Spend some time with your dog and play with it. These are puppies! They don't understand the english language - so if you say 'stop barking' or something, the dog has NO clue what you are saying so how is it supposed to obey?? Would you tell an infant 'stop crying' and if it doesn't punish it??? Needless to say, we are not in that class anymore. The instructor and I did not see eye to eye on how to train a dog.
I know they are popular here, but I just don't like the concept. People say their dogs "got it" after a few times wearing it, but the dog "got it" because it was closing around it's neck.
