Used to help prevent founder and obesity. The small circular opening in the bottom limits the amount of grass a horse or pony can consume yet does not hinder water intake. Attaches easily to your horse's halter with 4 point adjustable attachment system. Made of nylon webbing with a heavy leather bottom. Available in pony and horse sizes.
It didn't take long that the hole grew too big too. I have bought one in metal but my horse can't drink as it is too wide. They should combine the nylon one with an end tip that would be made of metal so they couldn't chew it.
I agree with oneof the other posters, thoughtit was just my donkey that chewed the hole bigger, it could stand to be a sturdier material. Aside from that, it has been great, cuts down how muchthe little fatty can pack away and keeps him from foundering. Another reviewer said it shouldn't have a hole, but it is a grazing muzzle, they are supposed to be able to eat some, just not as much or as quickly. If you don't want your horse to eat at all, you need a full muzzle or to put him on a dry lot.
