I have ponies which means at least one is in a muzzle. Over the years I have tried every version out there. The current pony has hyperesthesia from chronic Lyme disease which is improving with treatment. But it means he's very sensitive to touch. With one model he refused to move or drink. Another version, clear plastic, he just kept tearing up or getting off maybe with help from his pasture buddies. He's been in the GG & their halter for over 2 months now. Never gotten it off although it did tear in a corner. The warranty service was amazing! They replaced it quickly & recommended I use the corner straps. I made sure to follow their fitting instructions. His nose & chin initially got rubs on them. I recommend buying the stickers to prevent this and put on the muzzle when it's new if your horse has a good size chin. That solved the issue. I like how rain doesn't affect the muzzle and he has room to breathe. He seems happy in it too.
