We love the GG Equine Green Guard Diet Muzzle Insert because it is made from a soft, pliable, rubber-like material, that is non-toxic. It is secured into the bottom by pushing the insert tabs through matching slots* in the muzzle. Very secure once in place, these inserts can be removed but will take a bit of work to get out. But this is a good thing as it means your horse won't remove it before you do! 

The "diet" insert has 50% smaller holes to further restrict grazing. Reasons you may want to consider using an insert: 

• Further reduce your horse's intake. Note that this insert is severely restrictive, so please make sure your horse is used to grazing without an insert before using.
• Protect your muzzle from excessive wear and prolong its life 
• Have a softer material for your horse's grazing surface - the material is rubbery and softer than the muzzle itself. 

Sizes: Available in horse and pony muzzle sizes. 

CAUTION: Please ensure your horse is comfortable grazing in the GreenGuard muzzle prior to using inserts, especially the diet insert as it is extremely restrictive.
