Minis Out West, where did you get that 'Best Friends' muzzle?
I have a 13 YO Miniature gelding, born and raised here, who is a 'true' cribber/wind sucker; has been since very early in his life. He has never been confined to a stall, has a roomy stall w/ attached run, gets turned out in the arena or very large pen, etc., etc.--he just had the kind of personality to do such a thing, IMO (he is very sensitive to things around him, in every way, and reactive.)
I have his run set up so that there is only one 'opportunity' to crib, and there, it is on a panel bar that is covered w/ a piece of semi-rigid black poly pipe. It is the best 'answer' I've come up with...but even so, he has managed to wear his upper incisors down. He is indeed prone to ulcers; is currently undergoing a course of treatment. I am trying to get him 'used' to accepting U Gard over his concentrate feed-he is a VERY 'selective' eater, so it is hard to introduce anything new...but I've been VERY gradually increasing the U Gard, so hopefully, I can have him on it daily in future, to lessen the likelihood of a reoccurance of the 'fullblown' ulcers. So far, so good.
I tried the Weaver collar,and it did work, but eventually, rubbed him, and he looked totally miserable, so I gave it up. That muzzle looks as if it might be a better option!
Miniatures ARE horses, after all, and 'some' are going to be prone to occasional undesirable 'horsey' behaviors.
