Logan, we all know how much you love your dogs and would never ever do anything to hurt them. I think there are good obedience classes and very bad classes. Unfortunately the trainer we had believed in what she called tough love, pulling on the choke chains to get the dogs attention. Most of the dogs were Rottweilers, and other big dogs, but big dogs hurt just like little dogs. We vowed after that experience never to use a choke chain on any dog again.
