Product Overview
The ThinLine Flexible Filly Grazing Muzzle is designed to be softer, lighter, and less restrictive than traditional cage style muzzles. It allows horses, ponies, and drafts to enjoy turnout with reduced grass intake, supporting healthy weight management and reducing the risk of laminitis, colic, and obesity.
Constructed from a durable, pliable polymer, the muzzle is gentle on the skin, lips, and teeth, while remaining strong, UV resistant, and safe for daily use.
Key Features
- No rubbing or chafing
- Soft, flexible material that is gentle on the mouth
- Lightweight and non-restrictive
- Durable, UV resistant polymer
- Safe for use with all waterers, including automatic systems
- Well ventilated design
- Works best with the ThinLine Flexible Breakaway Halter
Why Use a Grazing Muzzle?
Controlled grazing can help prevent:
- Overconsumption of nutrient-rich grass
- Excessive weight gain
- Laminitis
- Colic
- Obesity
Grazing throughout the day supports digestive health by keeping stomach acids balanced. This muzzle allows horses to benefit from turnout while limiting intake safely and comfortably.
Fitting Instructions
A dedicated, well-fitting breakaway turnout halter is recommended.
- Use the included paper ties or string to determine the correct attachment holes.
- Attach the two triangle cut fins to the halter's side rings.
- Attach three fins to the noseband and three to the chin band.
- Ensure the muzzle sits close to, but not touching, the horse's nose. Adjust chin fins if needed.
- Once satisfied with the fit, replace paper ties with the included cable ties.
- Trim excess fin material above the top hole being used.
If the horse attempts to eat from the sides, check:
- Muzzle height (raise if too low)
- Even spacing of fins
- Correct muzzle size
Additional Fitting Tips
- Introduce gradually: start with 10–15 minutes and supervise.
- With the head lowered, ensure approximately half an inch of clearance from the lips.
- If the horse struggles to access grass through the centre hole, the hole may be too small for the pasture conditions.
- A closer fit reduces the risk of stepping on and damaging the muzzle.
Care Instructions
- Machine wash in a net bag on cold with detergent and a teaspoon of bleach.
- For deeper cleaning, soak in dish soap with a capful of bleach.
Package Includes
- Grazing muzzle
