Dog Girth Sizes by Breed

If you need help determining your dog's girth size but do not have a measuring tool, we can help! CLICK HERE for a downloadable/printable yardstick. For instructions on how to fit your dog for a harness, watch the above video.

The list below provides examples of some dog breeds* approximate weight and girth size. These girth sizes are from AKC standard girths (show dog standards). If you do not own a "show quality" breed, we strongly urge you to measure your dogs girth to be certain. If there is any uncertainty about your dogs size, Give us a call at our toll-free number (877-221-6462) and we'll be happy to help!

Note: Keep in mind that harness sizing can vary greatly from manufacturer to manufacturer. One brands "small" differs from another brands "small" just like with human clothing. To ensure the proper fit, measure your dog with a soft tape rule* for accurate measurement. Our video shows exactly where and how to measure your dog's girth. If you do not have a tape rule, we have a paper ruler that you can print out here.

NOTE: Weights & Girths noted below are approximate. If you are unsure of the size you need, please contact us & we will help ensure you get the correct size.
