I am seriously considering a grazing muzzle for my 4 yr old, Banjo. He is a Morgan so highly susceptible to EMS/laminitis, and an extremely easy keeper. With the spring grass he is already getting very fat, and I do not have a lock off area. He is in training so gets some exercise every day, but it is not enough to keep his weight down. I have never used a grazing muzzle and wondered if anyone has recommendations re: brands, types, etc. Also, how safe are they? Do horses ever get their feet caught in them or anything? Can they be left on unsupervised? There are trees in his pasture, so I guess that is a risk. Do they make a breakaway type in case he does get hung up? He is a clever guy, so if there is a way he can get it off himself he will. He also has a bratty little brother who likes to pull of flymasks, etc.
