One horse on our farm is very mouthy and continuously pulls off one of the horse's fly mask. We have the Crusader fly mask with the nose piece and the overlapping Velcro jaw strap. We even put a break away halter over top the fly mask and he still pulls off it off. We have gone through several fly masks because they have become badly torn. We tried the skin tight mask with netting over the eyes and he still managed to somehow pull it off. Any ideas on how to keep the other horse from pulling it off? Thanks for all the help!
