Unlike Any Others. The Flexible Filly Grazing Muzzle is made of Supple, Lightweight Material. And Features An Adjustable Grazing Hole.

ThinLine Global introduces a muzzle with adjustable grazing hole size. And manufactured with food grade resins.

Grazing hole sizes.

Veterinarian recommendations for safe grazing in a muzzle are a 3.5 to 4 cm grazing hole for 24/7, full time grazing.  And 2 to 2.5 cm for restricted grazing, often required for horses with metabolic issues.  The industry standard is 3cm and grazing holes are not adjustable.

Now it is easy to work with your veterinarian and ensure horses are safely turned out to graze on any pasture.  The 2cm hole of the Flexible Filly Muzzle may be enlarged to meet any grazing need. All you need, a pair of scissors.


The Flexible Filly Muzzle is a synthetic resin.  Resin, a substance of plant origin synthetically created to produce a polymer.  This gives it a high tensile strength (+700 psi). As well as and a tear strength of + 550 ibf/in.  It complies with FDA requirements for food safety. And it contains a natural UV protection. The light, thin appearance contradicts the extreme durability of the polymer material.

“Traditional” muzzles are rigid and present a variety of problems. They can rub or chafe a horse. Get full of debris, and become hot and uncomfortable.  As well as causing wear to horses’ teeth. However, for owners of horses or ponies that are Insulin Resistant or overweight, muzzles are a way of life. For them, the worry of colic or laminitis (founder) is constant. Now, with the Flexible Filly Muzzle, owners can choose this lightweight, flexible option as a means to appropriately limit their horses’ grazing.

Flexibility means comfort.

“This Grazing Muzzle is something horse owners won’t feel guilty about putting on their horses,” says Elaine, ThinLine Founder. “We approached the design of this muzzle from the perspective of the horses’ comfort and safety, as well as the owner’s peace of mind.  Compared to others.  Effective, lightweight, flexible, durable, and easy to care for.

Above all, the supple material is soft on equine faces, teeth, and lips. Preventing tooth wear and sores and general discomfort. And it’s UV-resistant, protecting equine noses from sunburn. The muzzle’s open design allows for extra airflow, further improving equine comfort. Built to be flexible, reducing complications for horses and owners . Also rated to break before your turnout halter. Low-profile zip ties come with the muzzle. Easily and securely fastened to any horse halter.  Custom halters designed to make the Flexible Filly Muzzle easy to apply and maintain are also available.

What the developers like best about this muzzle.

In our opinion, horses dislike wearing muzzles as they inhibit the horses ability to behave and play normally.  Horses use their mouths a great deal in play and in natural herd behavior.  Other muzzles restrict normal play.  The Flexible Filly muzzle is more like wearing a glove than a muzzle.  In our muzzle you will see your horse engage in community behaviors like wither grooming.  It is such a joy to witness.
