Product Information

For safety when working with biting and chewing dogs, our Guardian Gear® Lined Dog Muzzles are the choice of top handlers, trainers, and other professionals.

  • Made of strong nylon fabric
  • Inner seams provide extra support, adjustable strap for easy fit
  • Quick-release buckle

Why We Love It:

The Guardian Gear Lined Muzzles stop biting, barking and chewing behaviors in dogs.
There are several circumstances in which you might need a muzzle for your dog -- for grooming visits, veterinary visits, and for dogs that act aggressively towards other dogs.
Dog owners that have pets that generally don't bite can benefit from having a muzzle in their first aid kit. Even gentle pets are prone to biting when they are injured. Make sure your pet can get the treatment they need without becoming injured yourself with our safety muzzle.
Dog muzzles may also be of benefit for problem chewers -- whether the dog is chewing on himself or exhibiting other inappropriate chewing behaviors. 
Dog groomers, veterinarians, and animal husbandry providers can benefit from having several sizes of dog muzzles on hand. This sturdy nylon fabric dog muzzle is available in nine sizes to fit most breeds.
For snub-nosed breeds and cats, look for our specialty muzzles as well. 
Caution: Always directly supervise pets wearing muzzles as they may inhibit a dog's ability to pant and cool themselves. 
Made of 100% Nylon. Machine wash in cold water on gentle cycle. Line dry.

The muzzle was very nice. It didn't fit my dog.So that is all I can say.

I got this for my yorkie, for her barking. It was to big so it will go back. I will get a smaller size I do like it.

Not for Small Breeds

Dog muzzle

This is a very thin light weight muzzle. It was too large for my 65 pound Pit mix so I sent it back.

Good muzzle

Posted On 03/03/16 by Amaya from East,    Yes, Amaya recommends this product!
This is a good temporary muzzle that I use for vet visits. My dog is 8.5 lbs and has a chihuahua snout so size 0 was perfect for her. This also fit my 12 lbs Yorkie mix too. The muzzle's inner circumference is 4.5 inches. If you have a fussy dog or one that is unfamiliar with muzzles, ease them into it with training. Don't just try to put it on them. I've been playing fetch and feeding my dogs treats through the muzzle (small turkey pieces). So, that way, they associate the muzzle with things they love.

The quick release buckle falls off the head strap too easily. They need to redesign that part so it can be secure when a dog rolls or rubs its head trying to get it off. My dogs haven't done that but yours might.

Works OK but Sizing was Difficult to Determine

Posted On 06/30/15 by Lisa H from Elgin, IL    Yes, Lisa H recommends this product!
I purchased this for my pitbull, Roxy, who hates getting her nails clipped. I would only need it for short times so I opted for the least expensive muzzle.

The listing and the package state "Lined Nylon Muzzle." It is not fully lined. The only lining is a thin piece (quarter inch) of lightweight felt around the very inside tip of the muzzle part by the nose.

Roxy's snout measurement is 9.5". So I opted for the Size 5, stating online a 10" snout (with the disclaimer online stating this is the size of the actual product). The actual product is 9.5" at the nose tip The actual packaging states a Size 5 snout measurement to be 8-1/4", which is way off.

Anyways, it fits just ok. I would have preferred it to be a little closer to her nose, as it is a little on the loose side and she might still be able to "nip," although not bite. The circumference around the nose is not adjustable, but the back strap is adjustable.

It was ok for the little I paid for it, and will keep and use it.

Perfect fit

I like this much better than the leather cage looking ones. my dog actually didn't mind having it on

Strong, well made, humane muzzle

I like this muzzle because the dog can still drink while wearing it, but cannot open it's mouth wide enough to bite. I trained a dog to get used to wearing it using the Lickety Stik treat in a roll on container also sold by BaxterBoo.

good buy

I need to order a second smaller harness. Customer service recommended one size too big for my Maltese. I will return one of them.
