Taking your Dog's Measurements Correctly

Taking thorough measurements of your dog is essential for selecting the correct harness size. The correct harness size is determined by your dog's chest girth measurement (as seen in the diagram below) - place four fingers behind your dog's front legs and measure around your dog's body from that point.

Optimum Load Distribution
Based on mathematical equations, each IDC Powerharness size has a high-quality chest strap designed with a specific size and angle for effective load distribution.

Fitting the Harness on your Dog

It is important to ensure that the chest strap and lower strap are adjusted correctly. An improper fitting may cause discomfort or injury.

If the harness is fitted too tight, the buckle rubs against the dog's skin near the armpit area which may lead to chafing. If the harness straps are too loose, your dog may be able to slide out of the harness by backing out of it.

Correct Fitting

Once the harness is on your dog, you should be able to fit your fingers between the harness and your dogs back. A properly fitted harness will keep you in control while no unnecessary pressure is applied to other parts of your dog's body.
