954 That’s the magic of a properly used prong. He looks like he doesn’t need one because he was trained with one. If you take away the stigma associated with them being used incorrectly and the way they look, prongs can be used with less force than any other leash collar and are the safest for the neck. This all equals a dog that enjoys the training more.
I use either a starmark or prong on all my dogs as the training and forever collar depending on how hard the dog is. Nothing safer to train with and nothing gentler to maintain with.
