X-Back Measurement Guide & Size Chart

This section describes how to  measure your dog for an X-Back pulling harness.  We can't determine what size your dog requires with only the breed type and weight because dogs come in all shapes and sizes - even within breeds!

Thank you!

Measuring tips:

  1. Use a cloth measuring tape or a string. (If you use a string, mark the measurement on the string and compare it to a ruler for accuracy).
  2. You want the tape or string snug, but not tight.
  3. Measure the dog, not the fur. If the dog has thick fur, dig through their hair to find the proper reference points.
  4. Take the measurements three times. The results will vary slightly, but there should not be large discrepancies, or you can assume you’re not measuring correctly. Consider an average of the three measurements.
  5. The dog must be standing squarely on all fours, with their back straight.
  6. Have someone help you hold the dog while you measure.

X-Back Harness Size Guide

Tips to determine proper dog harness size:

We've added this page to help you identify the correct harness size for your dog without contacting us. However, if you need help figuring this out don't hesitate to call or Email us and we'll gladly help you. Phone: 1-800-355-5575 or 218-828-0513.

  1. If you're a recreational user, you may not find a harness that fits each measurement exactly and that is okay.

  2. If you're a competition racer a perfectly fit harness can make a difference between first and second place due to your dogs ability to work efficiently and effectively.

  3. Point A to B is the Neck Measurement (double for circumference) and find the harnesses that are within 1" of your measurement. For the recreational user always go to the next largest size if the measurement falls between sizes. Your neck size should be 4-6" larger than your dogs collar size (Noted as E on the image below). If it's not, take the measurement again because the neck measurement may be wrong. (There are exceptions to this but we've found this to be the case most times).

  4. Point A to Point C: The Back Length measurement should be within 1-2 inches to fit well.

  5. Point B to Point C: The Chest to Tail measurement should be within 1-1.5 inches to fit well.

  6. If your harness measurements do not fall within these guidelines consider the Adjustable One Harness.
