Grazing muzzles for horses: what are they?

A grazing muzzle may not look like they most attractive piece of your horses kit but they serve a very useful purpose - to prevent your horse or pony from over eating when turned out in the field. Controlling grass intake is important if you wish to manage your horses weight or they are prone to laminitis. A horse grazing muzzle has a number of holes through which your horse can only bite smaller areas of grass and therefore limits the amount they can eat over a period of time.

Our range includes different styles of grazing muzzles as well as head collars designed specifically to work with a grazing muzzle. Find brands including Greenguard, Shires, Roma and more in a variety of colours and sizes from Pony to X Full. We also have deluxe padded versions for enhanced comfort.

All About Grazing Muzzles

Research has shown that grazing muzzles can substantially reduce a horse’s intake of forage. Such a reduction could be highly beneficial for horses that are overweight or prone to laminitis. But muzzles may not be the right choice for every horse. Here’s what you need to know if you are considering investing in a grazing muzzle.

Medical Considerations

If your horse is gaining weight it is important to establish why. Equine obesity can be associated with underlying metabolic conditions and this possibility should be explored before using a muzzle. Equine Metabolic Syndrome (EMS) and Pituitary Pars Intermedia Dysfunction (PPID), also known as Equine Cushings Disease may be behind your horse’s weight issues. It is crucial that a vet examines your horse and the appropriate weight management plan instituted. This could include the use of a muzzle.

Reducing Forage Intake

There have been several studies which have attempted to establish the effectiveness of Grazing Muzzles at reducing food intake. The results have varied dramatically and have suggested that muzzles reduce intake by between 30% and 83%.

One study looked at what happens when horses are muzzled for a period of time and then given access to unrestricted grazing. The horses ate more whilst unrestricted to compensate for the time that they were wearing the muzzle. This finding suggests that unless a horse is always muzzled when grazing, there may be no benefits overall.

Compensatory eating is of particular concern for laminitic horses. Removal of a muzzle on lush grazing may rapidly increase their water-soluble carbohydrate intake which puts the horse at risk of a laminitic episode. There is anecdotal evidence which suggests that horses wearing grazing muzzles spend a greater proportion of their time foraging than non-muzzled horses and yet still manage to lose weight. Further research is certainly required as many of the studies conducted thus far have focussed on ponies rather than horses. It would also be useful to explore the impact of the muzzles on herd dynamics, social behaviour and individual behaviour.

Potential Issues with Muzzles

Some horses may experience problems with wearing a muzzle. Grazing muzzles can result in rubbing on the poll, behind the ears, on top of the horse’s muzzle and to the points of their cheek bones. It is vital to ensure that any grazing muzzle fits correctly.

Debris including sand and mud can collect inside the muzzle and the use of the muzzle could impact a horse’s dental health. Horses shouldn't wear muzzles on short grazing as their incisors would be at risk of abnormal wear. Muzzled horses can also struggle to consume exceptionally long blades of grass. Some animals will become highly frustrated with the muzzle and this could result in them bashing the muzzle on the ground or exhibiting other distressing behaviours.

There is a risk that a horse could catch their muzzle in a tree or bush. So remove for fence off any potential hazards you see. It is important to remember that a muzzle will impede a horse’s ability to groom, defend itself and communicate with others via facial expressions.


Grazing muzzles can be effective tools in helping your horse to lose weight. However, closely monitor their weight to ensure that the horses lose the pounds at an appropriate rate. It is vital to establish the optimum length of time that the muzzle should be worn for, to check that it is fitted correctly and to satisfy yourself that it is causing no distress or discomfort to the horse. Introduce muzzles gradually to your horse and make sure they are not wearing a muzzle 24/7. Also control your horses' food intake when they aren’t wearing the muzzle to prevent compensatory eating.

Introducing a Horse Grazing Muzzle

If this is your first grazing muzzle for your horse, it is best to introduce it gradually, for short periods at a time and in a rewarding way. Ensure it fits correctly and isn't pinching or too tight / loose for them. Check that your horse can drink adequately through the muzzle and that they have got the hang of grazing before leaving them for longer periods of time.

Use with Consideration

Never leave your horse wearing a grazing muzzle 24/7 - it is generally advised not to leave it on longer than 10 hours but each horse has different requirements. You will need to continually monitor your horse's condition, weight and behaviour and adjust the use of the grazing muzzle accordingly.

Although you are trying to reduce the amount of grass that your horse is consuming it is still important to make sure they still have plenty of fibre and a healthy balanced diet. If you need any further advice please contact an equine nutritionist or your vet.
