How to Measure Your Jack Russell Terrier

Measurements are needed for all coat orders. You will need your Jack Russell Terrier's weight, neck, length, and chest circumference measurements in order to select the correct size and place an order. Remember that our coats are breed specific, so Jack Russell Terrier coat sizes are unique to the breed and not intended for another breed.

After measuring your Jack Russell Terrier, enter your dog's measurements in the Get Your Dog Fitted area. Use your dog's measurements to select the best coat size for your dog. These are standard Jack Russell Terrier sizes, and are not customized. If your Jack Russell Terrier has unusual proportions, order a custom dog coat to fit your dog.
