are zip ties required for it to stay on the halter? How are they used?

The zip ties are required and are used to attach the muzzle to the halter.

What is the size of the hole?
Answer by ChewyMay 04, 2022
The grazing hole is adjustable. The restricted size is 2.5 centimeters and the regular size is 3.5 centimeters.

What do I need to measure?
Answer by ChewyMay 25, 2021
To measure, while your halter is on your horse you can measure from D-ring to D-ring on your halter under the horse's muzzle and add about 1 inch to that. The Horse Muzzle sizes should be based on the size of your horse. For instance, the pony halter is suitable for a pony muzzle.

Working well!

My mare was getting sores all over her muzzle with traditional grazing muzzles. I would have to tie them to her halter which was not very safe. I have been using the FF now for three weeks and it has stayed on. It has not worn or torn in any place. The muzzle did rub her with some of the edges and the top front. I covered the areas with small pieces of duct tape and this has stopped the rubbing. She seems to be happier and cooler using this one and I don't’ see as much as sweat or effort to eat. It’s thin, but strong. I like that about it. I bought the matching halter and would do that again. It works better due to the ties going through the muzzle instead of them rubbing with the horse and causing issues. Keep in mind that my girl is not one who tries to remove her muzzles and the worst that has happened is that she got it off one ear once but it was still on when found her. She wears it 12-13 hours a day. I don’t know how it would work with a muzzle Houdini. It is expensive but if this one lasts through a couple of summers, I will continue to use them.

I refuse to use the 'basket' muzzles on my horses, they are horrible for their necks, and so hot and rub terribly. I've used the original European (flatter) Greenguards for years, but they can be hard to fit, and the new square style rubbed off my horses chin in hours. These are wonderful! To be fair, a pain to fit, but worth the effort. I cut the whole a bit larger for my less insulin resistant 'kids,' and padded out the halter noseband to keep it from hanging too low. The real test came when my mare managed to catch it in the automatic waterer. I was sure it would just come apart, but the zip ties did exactly what they were supposed to do, and she was unscathed, as was the actual muzzle. Well worth the price of a few extra zip ties. I would recommend cutting the pieces above the nostrils a bit so they can be spaced better without being over the actual nostril, but overall these are working fabulously for all my seniors who are founder risks, allowing them to be out all day with their buddies.

didn't work

Horse hated it and we couldn't get it to fit so she couldn't get around it. Eventually ate the plastic to make the hole bigger on the bottom and threw it away.

Best Muzzle!

This muzzle stays in place allowing my horse to spend a longer period of time outside in the pasture.

Wears out too quickly

I really like a lot of things about this muzzle. It is lightweight, doesn’t absorb moisture and doesn’t cause rubs or sores on horse’s muzzle or face. Besides the one I bought for my pony, I recommended this muzzle to several of my clients. Much to our dismay, in some instances the hole began to fray and wear out within one month to one week. The one I purchased lasted about 8 weeks before it started coming apart at the hole. Not the typical wear you see in a Tough 1 muzzle that is a gradual thinning, but a ripping of the material causing a flap that irritates the horse’s gums. For the price of these muzzles I would expect to get a season out of one. My horses are on night turn out, so wear them about 12 hours a day.

Total lifesaver

This has been a literal life saver for my Cushings gelding. He refused to wear any other brand of muzzle. He was extremely overweight and after using all Spring and early Summer he’s back to a healthy weight. He can breathe, drink, lick salt and eat small amounts without feeling trapped! I’m buying a back up!

More affordable & comfortable muzzle

Flexible Filly grazing muzzle was about 30% cheaper & seems more comfortable than the Green Guard muzzle & LOTS more airy & softer than the black ones. I DID have to use a sharp box cutter to enlarge the hole a bit. This material is TOUGH but flexible. I attached it to a halter that has fuzzy padding on the nose. Set up is tedious, but once you get it done, daily use is easy.

Great product...even my sneaky mare can't get out of this

I have gone through numerous types of muzzles. So far this is the only one my mare hasn't figured out how to get out of....I appreciate the adjustability.

Great design

I was skeptical at first of these grazing muzzles but was intrigued to read how they drain faster when horses drink than other muzzles on the market. I feel badly enough my Arabians need to wear muzzles 100% of the time out on the pasture this year. Didn’t feel like adding to their discomfort. Adjusting the muzzles on the halters took some trial and error on my part. I wasn’t sure if the additional zip ties the company sold were worth it. After using a few regular zip ties I found I appreciated the Flexible Filly ones because they angle the cut portion so it doesn’t stick out as much. I ended up using a few regular ones and just filed the cut portion down so there weren’t any sharp areas. Additionally, I cut the grazing hole slightly larger for my mare one time but my gelding couldn’t figure out how to eat with his muzzle so I ended up trimming his twice. Overall, I think buying these muzzles was 100% worth it. They have been used 24/7 for over a month and show very little wear. I’m pretty confident they will last at least a few grazing seasons.

Horses can breathe easier!

This appears to be a good product, though expensive. Reason for 4 stars is I am unsure of its durability, since it is designed to break before the halter does. So far so good, and my girl can be tough on muzzles trying to get them off. She has been turned out 2 hrs. am and 2 hrs. pm in this muzzle for 2 weeks. She is certainly more comfortable in this than any of her other muzzles and this will be good for her on hot days. There was a little frustration at first due of the small opening but that is what she needs, (tough love!). This stopped after a hour or so. I attached it to a regular adjustable breakaway halter due to cost. I added a sheepskin fleece nose piece off the "midieval" muzzle I had, and it worked well to protect aganist the tie wraps rubbing. They do run big. Got the cob/horse and it fit my quarterhorse with room to spare. It would be too big for my welsh pony.
