Out of 8 horses in our barn, 4 use grazing muzzles when they are out on the grass. My 2 are on for weight control, on at night, off during the day when one goes on dry lot and the other in a stall. One boarders horse wears one when she is out, even when in a field with minimal grass, since she is elderly, and founders just looking at spring grass. The mini-well, to prevent founder also, altho she is tricky, and gets it off occassionally.
I love them, except for the rubs they tend to get under their chins. I would caution tho-I read this spring....don;t remember where-that if you leave them out on grass during the time the muzzle is off, they will inhale as much grass during that time only as they would have without the muzzle the whole time. In other words, they make up for lost time.
We have not had issues with them getting caught, only occassionally getting them off, particularly with a fly mask on.
