COMFORT HARNESS SIZING GUIDELINES
Just like us, no two dogs are the same. We have provided a guideline for which size dog harness will fit the breed of dog. The guide should help you select your harness, but we recommend measuring your dog before ordering, to be sure.
Measuring for your dog for a harness:
Ensure your dog is standing still
Measure using a fabric tape measure or string
Measure the chest immediately behind the forelegs and immediately in front. Both sizes should fit within the adjustable range.
Dog's Neck Size - the sizes below indicate the size of the dog's body. We have allowed a small amount of space between the body size and harness size.
