Best Grazing Muzzle For Horses – The Ultimate Guide!

Last Updated on January 25, 2023

Obesity in horses is unfortunately an all too common problem, but are grazing muzzles the answer? Choosing the best grazing muzzle for horses can be a minefield, but we’ve got everything you need to know right here!

A chubby pony may look cute, but excess weight in horses can cause many problems. Obesity is one of the highest health risk factors our domesticated horses face, and it is our responsibility to keep our horses at a healthy body weight.

When horses and ponies spend all day outside in a pasture, it is all too easy for them to consume too much grass.  A common solution for this is using a grazing muzzle, and the best grazing muzzle for horses can help to moderate your horse’s food intake and keep them at a healthy body weight.

Some grazing muzzles are preferred over others for different types of horses, different situations, and different climates.  Today we are going to take a look at the reasoning behind using a grazing muzzle, some horse grazing muzzle problems, and how to choose the best grazing muzzle for horses.

Why Use a Grazing Muzzle For Horses?

Every horse has different eating patterns, varying metabolism, and fluctuating energy requirements.  For example, native ponies and cold-blooded draft breeds are typically food-driven and it is very easy to keep weight on a pony. You will often hear owners of these tough and resilient horse breeds saying that they can get fat on fresh air!

On the other hand, hot-blooded horse breeds such as Thoroughbreds and Arabians are notoriously difficult to put and keep weight on. They are not as food drove, to the point of ignoring their food if they don’t like it. Their high metabolism and energy levels mean that they often lose weight despite being fed adequate amounts of food.

So, where do grazing muzzles come into this?

Well, when horses are turned outside in a grass pasture some horses will only graze until they are full, whilst other horses will graze every possible minute that they have access to grass. Horses that are prone to putting on weight are normally those with low energy requirements, who are adapted to survive on rough, low-nutrition grazing. When we turn these horses and ponies out onto lush, sweet grassland, they overeat and quickly put on weight.

Eating forage such as grass is essential for maintaining the health of a horse’s digestive system, but too much grass can add too much sugar to a horse’s diet. A heightened level of sugar can not only cause unhealthy weight gain but can also increase a horse’s likelihood of getting laminitis. When a horse has laminitis, the soft tissues within the hoof capsule become inflamed, causing severe lameness and structural changes within the hoof.


So, for health reasons, it is often necessary to decrease a horse’s food consumption of food. A good place to start is to cut back on their grain and hay intake. However, you may not be able to cut these out entirely, as grain and hay contain nutrients crucial to a horse’s diet.

Another solution is to cut back on the horse’s turnout time, thus decreasing the time it has access to grass. This will obviously cut down the amount the horse can eat, but keeping a horse confined to a stable or barn for long periods can be very detrimental to its well-being.

Adequate turnout time is vital for your horse to exercise, socialize with other horses, and wander freely out of its stall. Horses that are kept confined for long periods often suffer from health problems such as gastric ulcers, stress, and reduced intestinal mobility. They can become depressed and may develop behavioral vices such as weaving, windsucking, and box walking.

Studies have also shown that reducing the time your horse is turned out may not necessarily restrict the amount of grass it eats. This is because horses seem to learn that they may only be out on the grass for a limited period, and they will eat faster to compensate for this.

So, what is the answer here? Many horse owners who need to reduce their horse’s grass intake turn to grazing muzzles to solve the problem.

A grazing muzzle is a piece of equipment that goes over the mouth of the horse. They can either be attached to a halter or come built into a halter and are put on the horse whenever it is turned out to graze.

A grazing muzzle does not prevent a horse from eating grass entirely, but it should decrease the amount of grass a horse can eat whilst out in the paddock.  The best grazing muzzle for horses should allow your horse to enjoy their full turnout time, and enable them to nibble at grass without gorging themselves.

Potential Problems With Grazing Muzzles For Horses

Using the best grazing muzzle for horses can be a great solution for slimming down your overweight equine friends, but they are not without their flaws. It is vital to understand the potential problems caused by these handy pieces of equipment when selecting the best grazing muzzle for horses.

Traditionally, grazing muzzles were made from materials such as canvas or nylon.  Several notorious problems with these grazing muzzles include friction rubs, durability, decreased drinking in horses wearing them, and airflow in extreme heat situations.

When a horse grazes, it touches its mouth to the ground, right next to its hooves, to bite off grass at ground level with its incisor teeth. This means that dirt, stones, grass, and other debris are highly likely to get stuck inside a horse’s muzzle while a horse is outside trying to graze.  This debris will then rub against the horse’s face, leading to sores and general discomfort for the horse.

Using a Grazing Muzzle, and Which Grazing Muzzle is Best

Another problem with grazing muzzles is that some horses quickly work out how to remove them. They can become dislodged when the horse rubs on fence posts and gates, or through rough play with other horses. A good grazing muzzle needs to be robust and durable to withstand the physical strain that it may be put under.

Grazing muzzles also reduce the opportunities for horses to play and mutually groom with other horses in the field. Horses use their mouths for many things other than grazing, and a muzzle can reduce these socializing opportunities. To compensate for this, it is a good idea to turn your horse out in a pen with other horses for playtime every day.

In some situations, using a grazing muzzle may discourage your horse from drinking.  When the horse drinks from the water trough, the muzzle can fill with water.  The water will drain out through the gaps, but this may happen slowly and cause your horse to choke or panic, feeling like it cannot breathe or like it is drowning.  Horses that experience this often refuse to drink while wearing a muzzle.

Finally, poor quality or badly fitted grazing muzzle can restrict airflow when a horse tries to breathe.  Horses should be able to breathe normally while wearing a muzzle, but in extreme heat and humidity conditions, where there is no wind and the air is stale, horses have a harder time breathing on their own.  With a horse muzzle, this situation is escalated, which can be detrimental to the horse.

Is a Grazing Muzzle Cruel?

Whilst you’d struggle to find a horse that enjoys wearing a grazing muzzle, most horse owners will agree that this is the best solution for the horse. Putting a grazing muzzle on a horse means that it can spend a normal amount of time out on the grass with its equine friends, and it can still eat some grass.

So, whilst grazing muzzles do not look particularly pleasant, the alternatives are far less desirable. Simply letting the horse eat as much grass as it wants will lead to obesity, which can cause many detrimental health problems to the horse. Keeping the horse confined to a stall or barn will limit its opportunities to play, exercise, and socialize, and can lead to depression and stress-related behavioral problems.
