I've had this halter for one week and it has made a HUGE difference. I put this halter on my 10mth, 42kg enthusiastic pup and he instantly stopped pulling. He is finally walking at an acceptable pace with me, and my arms, shoulders, hands and knees have begun to feel better. That on its own is a massive relief. No more sudden lunging and direction changes at things that take his fancy. He can still roam to the extent of the lead but he can't pull like draught horse ploughing the bottom 40 acres. He's fusses a bit trying to rub the halter off on grass, trees, my leg from time to time but he is always happy to put it on and doesn't fret about it. Solidly built halter and the only one I had seen with a padded nose strap which seems to make a big difference as I know of other dogs who don't have padded straps on their halters and they have more issues with the dogs trying to get out of them. All in all, highly recommend this halter for all dogs and relief from associated body aches and pains.
