S.L.
We have a standard Poodle who is 71 lbs and when he was a puppy at about 45 lbs. he would jerk me and pull me with the collar on and nearly pulled my arm out of socket. I was advised to get the Gentle Leader and all pulling stopped, he walks by me and yet I let him go on a leash farther out and he is more free but never pulls or jerks me. He was groomed once when they decided to just use the collar, which he does have one on, and they said he pulled and jerked them and they put on the Gentle Leader I'd left and couldn't believe it was the same dog. It just mean that you are in charge and not he dog by the way it works. I would recommend that and they come in all sizes and work.
