I know many people are against this tool. However, hear me out.
I've walked Behr two times now for over 40 minutes and we've had no problem. I don't even have to use it. He doesn't dart toward other dogs, squirrels, or people. It's great. I think it has lifted my confidence with walking him.
Tommy, our trainer said that soon we will just keep it on his neck, but the leash won't be connected. We are using it as a learning tool, not forever. Will is still pretty skeptical, but he doesn't walk Behr at 5pm like I do.
Here are some links Tommy gave us. Some info on prong collars:
