      Horse grazing muzzles are a must for many horses but discomfort is not.

      Try a natural grazing muzzle.  Our research determined horses dislike muzzles because they cannot behave naturally in them.  With the historical cage-like or bucket-like muzzles, horses are unable to engage in social activities like wither scratching or other playful interactions resulting in social and emotional health in horse herds.

Constructed of a durable and pliable material that radically improves the horses’ feel. It is effective while also being soft on equine teeth and lips.

      What to know about Equine grazing muzzle center hole sizes.

      Veterinary Recommendations for grazing muzzles hole sizes are as follows.

      24/7 Full-time grazing in a muzzle; 3.5 to 4 cm.

      Restricted grazing; for horses who require substantially less sugar intake; 2 to 2.5 cm.

      The most common grazing hole size on the market is about 3cm and is not adjustable.

      Full-Time Grazing in a Muzzle:

      Recently, many horse owners prefer to leave their horse on pasture in a grazing muzzle full time – 24/7, which has created a demand for a larger grazing opening. With an industry-standard opening of under 3 cm, the roughage intake is often limited considerably. The digestion of a horse needs a minimum amount of dry matter to function properly and healthily. This minimum amount of dry matter is not achieved with a 24/7 restriction with an opening of 3 cm or less.

      Owners should supplement feed in the form of hay, in order to guarantee the minimum intake in dry matter. Hay cannot be eaten, or only to a very limited extent, with an opening of under 3 cm, which means that the horse must actually be taken from the pasture, the muzzle taken off and then fed with hay and then back with a muzzle to the pasture.

      The Full  ThinLine Flexible Filly Grazing Muzzle has a larger opening than the average grazing muzzle, which made this muzzle unique. There are very few muzzles that are really suitable for 24/7 grazing.

      Highly Restricted Grazing in a muzzle:

      There is a lot of demand for a smaller hole for extremely limited grazing.  Horses with laminitis, insulin resistance or those on lush fields need careful management and a 3 cm or greater grazing hole is too large to effectively protect them.

      Therefore, ThinLine now offers muzzles with a 2.5cm grazing hole.

      The good news is, the flexible filly grazing muzzle limited hole size can be easily altered by horse owners for the perfect grazing opening.  ThinLine now offers muzzles with a 2.5 cm hole.  To create a larger hole simply mark your muzzle with a pen and use a pair of scissors to cut the size you need.
