To choose the perfect size collar or harness for your dog, use a measuring tape to measure the circumference of your dog's neck and chest.

Pro Tip: Place two fingers between the measuring tape and your dog's body. This ensures the product won't be too tight or too loose, but will sit comfortably.

If you are buying a gift or expecting a new puppy and can't measure them yet, we have created a convenient sizing chart below. This chart includes estimates based on common breeds and our hands-on experience over time to help you choose the best fit.

Please note: Breed recommendations are estimates only. We highly recommend measuring your dog before purchasing!
