I keep hear about the Premier Easy Walker and the Gentle Leader, do these help with a dog that pulls on leash? I have a 10 month old dog who is getting stronger and I am having a hard time with him pulling. I was a bit relaxed with his training when he was younger and now I am paying for it. I am being very diligent with him now but sometimes he pulls so much he chokes. Any and all recommendations and advise welcomed.
