Our German Shepherd mix is 70lbs of endless, uncontrolled energy and I have arthritis. Prior to prong collars, I had lost track of how many times he had put me on the ground. The old prong collar was hard to get on/off and I left it on for awhile and it hurt his neck. I've only had one problem with this collar. Once he tried to crawl under a car, caught the collar and it released. Since then, he constantly wears a plastic collar and I add the prong collar to go outside, to the vet, etc. It was a dog trainer that suggested Herm Sprenger.
