Hi, does anybody have any experience, positive & negative of one of these halti head collars? I've a 15 month old springer who still has no idea that he's meant to walk on a lead, not gallop & jump around like a landed fish 🙄 no amount of stinky treats or stopping when he pulls has ever worked yet, which is frustrating as he knows what he should be doing (think 2 seconds of walking followed by a lunge forward!) just chooses not to. I was wondering if this would help, as I have temporarily given up attempting to walk him on a lead as my shoulder being pulled every 3 seconds is getting really painful, so I'm just driving to off lead areas (luckily loadsa around us & he's amazing off lead) & releasing him. I don't want to get it if it hurts them or anything, just wondered if it would be a useful aid until he stops being a teenage twit? Thanks
