Field Guard Use

The patented OutFox® Field Guard is designed to help protect dogs’ eyes, ears, and noses from foxtail penetration while walking or running over trails or through grasses and while engaging in casual sniffing. Additionally, the Field Guard can be used to help prevent dogs from scavenging and eating harmful items and to help protect their faces from insects such as flies and mosquitoes.

The Field Guard is not a muzzle and should never be used as one, to prevent biting.  

This product allows for dogs to engage in activities normally, which includes picking up balls and sticks for play.  Please note, picking up or chewing, on balls or sticks, while wearing the Field Guard will wear it out faster.

Remember, remove foxtails and other debris from the Field Guard and your dogʼs coat as they appear. Inspect your dog thoroughly for foxtails after every outing. For information on how to wash and care for your Field Guard, please see the Care & Warnings page.

Fitting for Comfort

Putting on the Field Guard


  1. Cinch the elastic Field Guard opening to about the size of your dog's neck.
  2. Throw a treat in the Field Guard.
  3. Place the Field Guard close to the ground with opening parallel to the ground.
  4. S t r e t c h the opening as far open as possible. *This is the important part, do not pull the Field Guard over his head.
  5. Hold the opening parallel to the ground, under your dogs head.
  6. He will put his head down into it, to get the treat.
  7. Let the opening close around his neck, just behind the ears.

Field Guard Position

The position of the Field Guard on your dog is very important in creating a proper fit that ensures comfort.

A common mistake people make is pulling the Field Guard back too far down the neck. As shown above (right photo), when it is pulled back toward the collar, it tilts upwards and seats directly against the dog’s muzzle, and puts the panting room above his snout. This position irritates the dog’s nose and does not allow room to pant.

When the Field Guard is positioned correctly (left photo above), it should tip downward, with the top of the Field Guard resting lightly on the top of the dog’s head and leaving ample space in front of the dog’s nose.

Your dog should be able to pant unencumbered. Positioned correctly, there will be space below the dog’s chin for him to open his mouth for panting.

Space between the dog's nose and the end of the Field Guard should be 2″-3″ for medium and large dogs, and 1″-1½″ for small dogs.

Field Guard Straps

The straps are designed to tether the Field Guard to the dog’s collar. Leave some slack in the straps so when the dog puts his head down, the Field Guard does not get pulled back and out of position.

For your dog’s safety, the straps are designed to release if the Field Guard becomes caught on something so the dog will not become entangled.

Pointed Ears

Dogs with ears that stand up generally don’t have a problem with the Field Guard. It is designed to have a generous amount of space around the dogs head and the mesh is flexible but not stiff or soft. The Field Guard is light-weight and won’t be tight on their ears, but the ears will naturally fold down on their own. Their ears fold down the same as when they duck under a fence or go through a low dog door.
