The only thing that worked for Z was a head collar. I used the Gentle Leader with him, as at the time that was the only one I'd heard good things from. I didn't know then about aaaaallll the other head collars that are out there. Anyway, the turnaround method did nothing for Zeke, we could have walked a hole in the ground walking back and forth and he still would have been zooming one direction and then the other when I turned around. Stopping when he pulled did no good either, for him. Stopping and backing up did no good for him. I couldn't reward him either for coming back with anything but praise, because at the time he didn't have his tennis ball obsession and he had ZERO interest in food. Still has zero interest in food but he is now motivated by tennis balls. We tried a GL at the recommendation of a trainer friend of mine and he's been wonderful ever since. The great thing about head collars is that you CAN wean them off of them so that eventually you don't need it.
You DO have to do some conditioning to get them to like the head collar. It's a weird feeling for them, they are not used to things on their faces. Conditioning them to it is very important. I'm starting this tomorrow with the Lab I've been working with. Any method works with him, but his owner is very very petite and he's a big dog; she has trouble working with him with the turnaround method and the stopping-when-he-pulls method. He gets it, but she has a tough time handling him so she can't really work with him enough to get him good at it. So we're starting with the head collar tomorrow so she can handle him easier, as it is tougher for them to pull in a head collar.
