What will you need to fit the muzzle? – We recommend you commit a dedicated well fitting breakaway turnout halter to your muzzle or use the matching Thinline Flexible Field Safe Headcollar. It generally takes about 10 minutes to get everything perfect the first time you install a Flexible Filly Muzzle.

How to attach your Flexible Filly Grazing Muzzle?

Use the enclosed paper ties or a string to discover the best holes to secure your muzzle to your halter. The paper ties are a temporary tool allowing you to easily adjust the fit.

Two of the “fins” have a triangle cut out. These attach to the square (side) rings on your turnout halter. Three fins will connect to the noseband, one in the centre, the other two fall naturally to the sides of the centre.  Three fins will connect to the chin band; one in the centre, two naturally to the sides of the centre.

First, secure each triangle cut out fin with one of the enclosed low profile cable ties. Do not wrap the fins around the halter, doing so may cause rubs.

When properly installed, the muzzle should be close to but not touching the nose of the horse. If the muzzle is touching the nose simply make the fins under the chin longer, this will lift the muzzle away from the nose.

Once you are satisfied you have the correct holes aligned to the halter please remove the paper ties or string and permanently secure the muzzle with the included cable ties.

After finding the best fit for your horse, simply trim the excess fin material just above the top hole being used. It is fine to wait a day or two to ensure your muzzle is a comfortable distance from your horse’s mouth before trimming. The “keeper” on the cable tie is on the outside of the muzzle and the excess is facing down and trimmed close.

If you have fitted the muzzle properly and the muzzle is the correct size it will work famously. If you find there is too much grazing room be sure your fins are snugly secured to your halter. The fins should not move along the noseband. If it does simply pull the cable tie tighter.

What is the Flexible Filly Grazing Muzzle made from?

The grazing muzzle is made from one of the most durable polymers on the planet.  It is fungal, mould and UV resistant. It is safe, effective and durable. There are no “off-gassing” materials so they are safe near the nostrils. Even if accidentally ingested the polymers pass USA food safety regulations. The muzzle is ideal for slowing down speedy eaters, limiting grazing, and can help curb minor cribbing problems. The muzzle can also keep horses from chewing on leg wraps, wood, or blankets. It works extremely well with all automatic waterers and has UV protection which works much like sunscreen for those delicate noses.

Care Instructions: First, you can place the grazing muzzle in a net washing bag and wash on cold water with detergent and a teaspoon of bleach. Second, more extended clean, stick it in a bucket with dish soap and a cap full of bleach.

Returns and Warranty Information?

The Flexible Filly Grazing Muzzle comes with a full 6 month product replacement warranty from receipt for any faults with the material. Like most muzzles the Flexible Filly Grazing Muzzle will break under strain as a safety feature to stop your horse getting caught on fences etc. Using the muzzle with the ThinLine safety breakaway halter is an added safety feature as well.

**It is our experience this muzzle works on every horse when owners have the correct size and it is fitted properly and securely**
