My friend's german shorthair, Lady, is the worst puller I've ever seen. She tried pulling harnesses and other things, which did not work. Finally she tried the halti. It worked WONDERS for that dog. You couldn't even take her for a walk before...

I have a halti for Nebo also. He walks perfectly with that on...with the exception of stopping every now and then to scratch at it. He's never even come close to getting it off, nor has Lady.

You need to let the dog get used to it, as well as praise and treats....not just put it on and walk them on it....
