Have any of you ever used a dually halter? What problem were you trying to solve with it? Did it work?
I’m just curious because somehow I had never heard of this until recently even though it’s apparently been around for years. I’m always suspicious of gadgets promoted by famous trainers (like the magical 12 ft. rope). So COTHers what do you think–is the dually halter a useful tool or just another gimmick?
