Choosing a Grazing Muzzle

Grazing muzzles are an important tool for allowing certain horses to enjoy pasture turnout.


Horses are physiologically designed to graze nearly constantly (up to 15 hours a day), but health issues such as obesity and high risk for grass founder can make it necessary to restrict their grass intake. Though the idea of strapping a contraption on a horse’s face can seem like cruel and unusual punishment, it’s important to remember that by not using one on an at-risk horse, you may be literally “killing him with kindness.”

No matter which type of muzzle you choose, it’s important to know a few things:

The length of the pasture grass will affect how a muzzle works. If grass is very short, the horse’s teeth won’t be able to grasp it through the hole in the bottom of the muzzle.

Horses should not wear muzzles 24/7, so a modified turnout schedule may be necessary.

Muzzle use can affect herd dynamics; adjustments to turnout groups may be needed.

The original plastic basket-style grazing muzzles have seen many design upgrades to help keep them in place with less rubbing. Here’s a look at some of the different options on the market today.
