Good Fit ⇒ Comfort ⇒ Easy Acceptance!

The Field Guard is easily accepted by most dogs because it is engineered for comfort. The correct size will allow enough room for the dog to open his mouth and pant, and for air to circulate all around the dog’s face.

1) Measure the Head Length

  • Your dog should be looking, generally, straight ahead.
  • Use a piece of string or yarn, then measure against a ruler.
    • Using string allows you to skip trying to read the tape measure on the dog’s ever-moving head. Measuring goes faster because the dog isn’t as likely to move his head under a thin string as compared to the tape measure.
  • Measure from the base of the skull, straight, to the end of the nose.
  • For accuracy, measure 2 or 3 times.
  • PUPPY size is based on current head length.

    2) Choose Head Type

    Long Head Round or Furry Head, or Long Ears

    3) Choose Size

    Long Head Sizes Round or Furry Head, or Long Ears
    5½ - 7"   XXS
    7 - 8¼" XS

    If your dog's head length is less than 5½ inches or weighs less than 9 lbs, you will need to order a Custom Field Guard

    Don't forget about Positioning the Field Guard

    The correct Size and Position are the key to your dogs comfort and acceptance of the Field Guard.

    When the Field Guard is positioned correctly, 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.

    A common mistake people make is pulling the Field Guard back too far down the neck. 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.
