[header] How to measure a dog for a harness [title] Get a measuring tape. [step] While harnesses are often sold by the weight of a dog, it is good to use a measuring tape to get a more exact measurement. Combining your dog's weight and measurement in inches or centimeters will allow you to find the best possible harness size for your dog. <sep> (A) [substeps] With a measuring tape, measure the front of your dog's back. This will be the thinnest part of your dog's back and should be perpendicular to the ground. (B) [substeps] A standard measuring tape should be able to measure between a hip and torso. Feel free to also measure from your dog's rear end (s), as this will be the most accurate measurement used to show how your dog's hip or armpit should feel. (C) [substeps] You should start by measuring front, back, and sides of your dog's body. Measure from its shoulders to its midcalves, just below the tail. (D) [substeps] If your dog wiggles around a lot, then you may want to ask someone to help you. Have someone hold the dog's collar to keep him still while you take the measurement.
