Ordered replacement for muzzle I got several years ago (the first model) - got same size as before (cob/horse) but it's much smaller; got the smaller hole opening because the original lets her eat too much. So far I can't get it attached to new halter in a way that fits for her to eat and doesn't cause rubbing. Will try with diff halter and padding, because it is a good product. Trick with all muzzles seems to eventually come down to dealing with rubbing, if you leave them on for any length of time. Rubbing from this muzzle is only from halter, not the muzzle itself.
I was skeptical because of the big slats on the side of the muzzle and figured he’d destroy it in a day. Three weeks later, still intact and works great!
