Use the templates below to see if the Trident helmet will fit your dog. Print them all at once or try them one at a time. Please note that PDFs often auto scale to fit your paper size. You MUST make sure the templates print at 100% with NO PAGE SCALING.

​

For best results, cut out the templates and tape them onto cardboard to make them sturdy. Choose the best fit for each template type — W (width), L (length), S (snout). Use a tape measure for N (neck).

​

NOTE: Dogs that match the template W2 will have a less than ideal fit, and those matching W1 will have a very poor fit. W3 and W4 will have the best fit, provided all other measurements are within acceptable range.
