Not all of them, but most of them. Just look what they're subjected to.
I'm especially cringing at the crown piece. That's one of the most vulnerable areas on a horse and Schneider Saddlery is marketing this thing.
Ever met a horse who didn't like his ears touched? It's probably a trust issue. A horse's cervical vertebrae are pretty well protected until you get to the top of the neck, which is where the bones have the least protection. So if your horse lets you touch his ears and the area behind his skull, that says he trusts you.
This piece of shit would most definitely make a horse headshy. I can just see that curb strap pinching the hell out of there jaws.
Arabs are hot blooded anyway, so why add fuel to the fire? You KNOW any horse would be extremely upset if this was on his head. Imagine a flaky, two-year-old Arab colt. Yikes.
If you can't train a horse to square up and stand with a plain halter, you need to step back and reevaluate your skill level. And question whether or not you should even have horses. It doesn't take long for anyone who knows anything about horses to figure out who knows what. In the horse world, you can't hide incompetence or lack of knowledge. Everyone is gonna know, and you'll look like that much more of a fool if you try to deny it.
