May also be used as a training tool to discourage nipping?and cribbing. Added reinforcement for additional strength and durability.

Attaches to your leather or breakaway halter with 4 adjustable velcro straps, offering further breakaway capabilities.Q: Which muzzle size should I order?The best way to determine size it to measure your horse's face using the sizing chart below.To measure:1. Determine the style you would like and then refer to the sizing chart to choose a size. Most horses wear the same size muzzle as halter, but not always. After choosing a style and size,?note the depth and circumference of the muzzle. Because horses'?heads are generally tapered like an ice cream cone, measuring the circumference of?the face at the right spot is critical to finding the correct size muzzle.2. Stand to the side of your horse looking at the profile of his head. Start at the tip of his lips (where your hand would be if you were to give him a treat) and measure up towards his ears to the depth of whichever muzzle you think you need. For example, if I think my horse needs the horse size and I want the Deluxe style, I would measure up his face 7-1/2. 3. At this point, measure the circumference keeping the tape snug. For my example, if the circumference of my horse's face at this point is 23-24, the horse size Deluxe would most likely fit my?horse.? My horse will need at least an additional two inches for chewing and regular movement of the jaw.4. If you are in between sizes, get the larger size. The muzzles are intended to have a roomy fit.?
