Jack Russell Terrier Measuring Guide

Measurements are needed for all coat orders. After measuring your Jack Russell Terrier, use your dog's measurements to select the best coat size from our standard Jack Russell Terrier sizes. Our Jack Russell Terrier coats are tailored to the unique body of a Jack Russell Terrier, and are not intended to fit another breed.

You will need your Jack Russell Terrier's weight, length, and chest circumference measurements in order to select the correct size and place an order.

  • NECK (N): Measure the circumference midway between the ears and base of neck.
  • LENGTH (L): Measure along the back from between the shoulder blades to the base of the tail.
  • CHEST (C): Measure around the widest/deepest part of the chest — usually right behind the front legs.

THESE STANDARD SIZES FOR JACK RUSSELLS ONLY. Our breed-specific coats are not customized to your dog's measurements, so if your Jack Russell Terrier has unusual proportions, order a made-to-measure dog coat to fit your dog. 

Be sure your dog's chest girth falls within the parameters of the size you choose. If your Jack Russell is a puppy and still growing, read How do I choose a dog coat for my puppy?
