There are two different OutFox® Field Guard styles based on head shape:
Choose the type of style that will allow for air space between the dog’s head and Field Guard for best air circulation and cooling.
Regular head shapes – for the average head shape (ie hounds or shepherds)
Short/Wide – for short snouts (Pug, English Bulldog), wide or furry heads (Pit bulls or Labradoodles with long hair), or long ears (Bassett)
HOW TO MEASURE
REGULAR
Length: Measure at the top of the head, from the skull base to the end of the snout.
WIDE/SHORT
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 chart below, breed examples are only a rough guideline.
Please always measure your dog for exact sizing.
Note:
For flat snout dogs, (Boston Terrier/Pug/etc.) sizing is based on circumference.
For breeds with wide or furry heads, or those with very long ears (like Basset Hound) sizing is based on head length.
(If your dog measures on the borderline between sizes, choose the smaller size).
