Hi, I'm definately no expert but just a tip for the figure eight halti that I have found to be a godsend, and surprisingly gentle for the results you get. let your dog first get used to the halti in the house and garden. When first putting on the halti, hold a treat the other side of the loop that goes over his noise, and let the dog put his nose though and you just guide. Then attract attention away from the halti with training, toys or affection. As soon as he looks like he is going to pull it off with his foot, or on ground / furniture, remove it. Then try again the next day or later, reward with treat. You can clip the halti to his regular collar at the back of his head at first, so if he does pull it off while out, you haven't lost your dog. Then once used to haltie, clip it under the chin, which gives supurb control, although took a while with my doppy dog to even realise what was going on. Also when off the lead, remove the halti, and then he can't learn to take it off. A couple of days patience with getting him used to the halti and it's worked wonders for my springer, who is impossible on the lead. Although, still not perfect yet, he's coming along nicely. Gook luck
