Basically the question is: how do i get him to want to put it on? My pup is 9 months old so until now, he's just had a few cheap harnesses from the pet shop whilst he finishes up his growing and need to chew on the straps. He never enjoyed getting into those either and he'd back away as soon as i got it out of the cupboard. He's a fairly wary dog so in case he was just frightened of it, i spent a long time training him to let me touch him with it and so on, until he could step into it himself. It never really worked. He's very quick at picking up new concepts, he knew how to actually do what i was asking and could do it instantly but after a few days he started backing up again and i just had to sort of manhandle it onto him. I questioned if maybe he found the other harnesses uncomfortable or didn't like stepping in or something so i thought a nice new harness that fits well and goes over his head instead of legs, might be a good fresh start. Now like i say, he picks up new concepts very quickly, so he knew how to push his head in on command perfectly after two training sessions. He was happy enough to put the harness on the first few times but then he started backing up again. So every walk i would sit down with his treat bag and slowly click his every move until he'd shove his head in again. As soon as he'd got it on the first time, he'd be happy to put it on straight away for the next repetitions. These days, he doesn't even want to do it for treats, it's a real struggle. I can't understand the problem. He loves food, he loves his walks, the harness is loose and comfortable enough as far as i can tell and he knows what i want him to do, he just doesn't want to do it. The last couple of days, i've taking to tediously coaxing him into his harness and then rewarding him with treats and a game of fetch every time he does it, to show him that it really is fun to wear his harness. He'll put his head in straight away as soon as we've done it the first time, because he wants that ball. So i get the ball out along with the harness to show that we can play once he does what i ask, but he just really doesn't want to do it the first time and if i put that ball away, he'd be right back to backing away from me. That was really long-winded and i'm sorry, but i'm all out of ideas, i really don't know how to fix this, so any suggestions would be extremely welcome. I don't like to have to corner him into his harness because that can only make it worse. Oh, and he does the same thing to a collar so that option's out too.
