Revolutionizing Dog Apparel

Welcome to K9 Top Coat’s custom sizing program.

Choose your size with K9 Top Coat’s Perfect Sizer Tool. Choose from either of two methods.

K9 Top Coat has again revolutionized dog apparel by taking the guesswork out of choosing the correct size for your dog. Our K9 Top Coats can fit dogs from 4 lbs to 165 lbs. So, we felt a need to provide a better resource for choosing a size.

Our innovative program allows you to determine which garment is best for your needs, plus utilize our database to find the best fit for your dog. You can determine the correct size by using your dog’s approximate weight, by using 2 measurements taken from your dog, or both. Our interactive program is about 95% accurate. You will not find this type of resource on any other dog apparel website. We always strive to be the best.

There is also a specific page to instruct you on how to properly measure. Remember that the program is only as accurate as the information given. So, please review this page first if you are going to use the measurements option of the sizer. And remember to measure the top line from the SHOULDER BLADES to the base of the tail.
