Start Spring With Solutions for Sugary Grass

ThinLine offers the famous Flexible Filly Muzzle.

Each Spring, pastures, paddocks, and fields encounter their massive growth powered by warmer days, sunshine, and rain. This is a perfect recipe for high-quality, green, sugar-filled forage that your horse loves. However, to ensure horses remain healthy and avoid digestive and metabolic upset, they need to be slowly introduced to these lush and delicious pastures. Acclimating your horse to spring grass takes time, and requires slowly increasing the amount of time they have access to grass. The Flexible Filly Muzzle can greatly aid in this.

Studies have shown that horses with metabolic issues, like Cushing’s disease, insulin resistance, or “easy keepers” can benefit from using a muzzle to decrease the amount of sugary grass consumed. By doing this, these horses are at a much lower risk of developing laminitis, equine metabolic syndrome, and other preventable problems.

Why this muzzle?

This muzzle is softer, safer, and smarter than traditional cage/bucket-like situations of the past. The Flexible Filly Grazing Muzzle comes in 2 grazing hole sizes that can easily be enlarged with a pair of scissors,  allowing for options to fit your horse’s exact needs! For optimal grass intake management, ThinLine suggests using the restricted size during spring and utilizing the 3.5+cm hole size in the summer due to the increased grass thickness and size. However, it is recommended to talk with your veterinarian about your horse’s specific needs.


  • They are breathable, flexible, and offer UV protection that acts like sunscreen for those delicate noses.
  • Works well with automatic waterers and encourages proper equine hydration.
  • It will never rub, it’s lightweight, and allows horses to engage in natural behaviors.

Seems too good to be true? It’s not! ThinLine researched equine behavior to learn why other muzzles don’t do the trick so a simple solution for safer grazing could be created. Horses are still able to groom each other while wearing this muzzle, scratch themselves, and behave the way nature intended, like horses! Protect your horse this spring and talk to your veterinarian about grazing practices and management.
