I have a 6 month old pit puppy. I trained him to put his nose into the muzzle on his own and hes fine with it. I slowly introduced the hanging around the neck and he was fine. Eventually he was putting his nose into the muzzle on his own and letting me clip it around his head and i would leave it for a good 20 seconds and reward. I would never say no if he messed up, just simply pull away the muzzle. Now if i say muzzle and he willingly puts it on and lets me clip it, but problem is after alittle while he will start to pull it off with his paws (i try and distract him with other commands and treats but eventually it wears off) and ive been doing this for a few days. So i simply take off the muzzle then wait 30 seconds and reward him. He doesnt want it on for longer than 30 seconds any tips?
