Samantha Arlington, Massachusetts 8/29/2014 10:18:19 PM This article writer is an idiot who obviously uses the "petco/petsmart" way of training yet know nothing of a TRUE dog's body language. That being said certain dogs achieve more from positive reinforcement but this writer is biased and an idiot as I said before. I am 28 years old, have been raised around all breeds; collies, terriers etc and worked for THREE years in a dog day camp setting with numerous breeds and individual personalities. I know dog body language and behavior and the "click and treat" while working with SOME dogs at basic level does SHIT for a lot of dog breeds and individual personalities. I advise every dog owner look at THEIR dog's personality and do extensive research on THEIR dog's breed. The trainers who think "only positive reinforcement" are the ones who's client's dogs usually end up in the pound. Positive reinforcement is good but should be balanced by painless, shocking reprimands..
