There are two different OutFox® Field Guard sizes: one for dogs with regular head shapes & one for dogs with wide or furry heads, long ears, or short snouts.
(Pointy-eared dogs do fine in regular sized Field Guards)
How To Measure
Length: Measure at the top of the head, from the skull base to the end of the snout.
Circumference: Measure loosely around the largest part of the head: go gently over the ears. If the ears stand up, don’t measure up and over the ears.
In the charts below, breed examples are only a rough guideline.
Please always measure your dog for exact sizing.
Note: For breeds with wide or furry heads, or those with very long ears (like Basset Hound) sizing is based on head length.
For flat snout dogs, (Boston Terrier/Pug/etc.) sizing is based on circumference.
(If your dog measures on the borderline between sizes, choose the smaller size).
