Flexible Filly Grazing Muzzle FAQ

How do I choose the correct size Flexible Filly Grazing Muzzle for my horse?

Choose your muzzle size based on the halter size your horse typically wears. For example, if your horse wears a cob size halter, you’ll select the cob-horse size muzzle.

Does the Flexible Filly Grazing Muzzle work with automatic waterers?

Yes! The muzzle’s flexibility allows it to work with all automatic waters.

Do I need to buy the ThinLine Breakaway Halter to be able to use the muzzle?

Grazing Muzzle Halter zip tie close

Our muzzle works great with any breakaway halter. The ThinLine Halter is specially designed with keepers for the zip ties built into the noseband.  This does two things for you, it makes the muzzle rub fee and it places the muzzle fins in the perfect position.


How do I attach the muzzle to my halter?

Use the temporary fitting ties to find the correct holes on the muzzle. Once you’ve decided on the holes you’ll use to attach the muzzle, simply thread the zip tie through the hole directly below the noseband, around the noseband, and through the hole above the noseband. The side fins should be several holes shorter than the front and back fins. Be sure to secure tightly and then trim the excess length of the zip tie then trim away any length of the fins that extend over the noseband, rounding off the corners.

What can I do if my horse is eating out of the side of the muzzle?

  1. Lower your halter’s noseband and raise the muzzle so that it’s attached using the lower holes.
  2. It’s ok for the muzzle to be very close, even lightly touching, your horse’s lips. It will drop further away from the face when your horse’s head is down while grazing.
  3. The front and back fins should all be on the same hole.
  4. Ensure the side fins with the triangle cutouts are attached several holes shorter than the rest.
  5. If the above doesn’t do the trick, adjust the fins so that the front and rear center fins are 1-2 holes shorter than all of the rest.
  6. Still able to eat out of the side? Your muzzle may need to be exchanged for a smaller size.
Muzzle short in front
This muzzle is too far from the horse’s mouth. He will eat out of the sides.
muzzle move the back fin
This muzzle has the front fins too long so it will lay on the horses’ nose and he will eat out of the side.
muzzle move back
This muzzle is nearly perfect. I would attach two cable ties to the square ring to secure it.
muzzle side low
Since the square ring is lower than the noseband the side fin must be raised several holes.

Remember, it is more important to see how it fits while they are grazing!  This one is perfect.

The grazing muzzle may slow down cribbing, but will not prevent determined cribbers.

Is it ok for my horse to wear 24/7? 

Yes! This muzzle works great for horses out on pasture 24/7. Please check periodically to ensure all is working well.

Which grazing hole size should I choose? 

2.5 cm- Restricted grazing hole size is vet recommended for horses with medical needs requiring very limited forage intake.

3+ cm – Traditional size grazing hole is vet recommended for horses needing to be muzzled for general weight management.

How do I enlarge the grazing hole size?

To enlarge your grazing hole, trace a circle around the original hole for your desired size, then cut around the circle with scissors.
