I need the same help! My donkey is SO fat and all she gets is a small handful of grain. But, she is the “babysitter” in my horse pasture and I really can’t separate her. Plus, I would have to “round-up” the paddock in order to have a dry lot. I no longer muzzle her because 1. it did not seem to make any difference and 2. I found the muzzle hanging on the trailer hitch! Fortunately, it was on a break away so she was not hurt at all but it was a strong reminder that it is not really safe to keep a halter on your horse when the horse is turned out. (I don’t any anyway.) Should I just put the muzzle back on?
