Proper sizing of products is crucial to the safety and comfort of the pets wearing them.
Use these visuals as a guide for how to measure dogs for a collar or harness.

Dogs come in all shapes and sizes - each has a unique fit.

How to Measure

Use a measuring tape to measure around your dog's neck or chest.

HARNESS GIRTH - Measure around the broadest part of the dog's chest (girth) behind the front legs.

COLLAR NECK - Measure high on the dog's neck.

Allow for two fingers to slide between the collar or harness and the dog's neck or chest.
Add 1"-1.5" to your measurement and follow the chart below.

Estimate by Weight

Use dog's weight average to also guide your selection. Use measurement first and weight second for the best fit.

Your pup will appreciate a secure, snug and comfy collar or harness but all dogs are different.
