A well-fitted Field Guard is easily accepted by most dogs because it is engineered for comfort. The correct size allows room for the dog to open his mouth and pant, and for air circulation around the face that is necessary for cooling. If you want the best fit for your dog, use these measuring instructions for exact sizing.
Before March 2022, dogs with furry faces, extra long ears, or a blocky heads required an “O” size to allow space for necessary air circulation and cooling. All other dogs were able to utilize our regular size. With the announcement of our new sizes, we have eliminated the 'O' size.
The chart below is the New Size Guide Chart for all sizes in stock. Note that PUPPY size is and has always been based on current head length.
Measure your dog for correct sizing. Breed examples are just a rough guideline. If your dog's measurements are on the borderline between sizes: for XXS & XS, XS & S choose the smaller size; for S & M, M&L, L & XL choose the larger size.

*DISCLAIMER:
While the OutFox® Field Guard effectively helps to protect against foxtail penetration to a dog’s face, it is not 100% failproof. Because the product is made of a mesh, a material with a large number of closely spaced holes, there is always a possibility for foxtail seeds to penetrate the mesh. We recommend you inspect your dog if exposed to an area with a concentration of foxtails.
The Field Guard is designed to catch foxtails before they enter a dog’s nose or ears. So it is important to check the Field Guard regularly to remove any foxtails it catches and to check for puncture holes that compromise the integrity of the mesh.
