When measuring your dog’s neck, include the space for 2 fingers to slide under comfortably in your measurement. Our size guide works on the available holes on the collars, so we would encourage you to aim for a collar size that uses one of the middle holes. The breeds suggested against each size are based on averages. Please measure your dog for accurate sizing – every dog is different! For more information, check out our blog to help you choose the perfect size.

How to measure for our martingale collars:
Use a soft tape to measure the widest part of your dog’s head and neck, keeping it fairly snug. Using the biggest measurement, add 5cm or 2 inches. Now use this new figure when referring to the size chart for the size needed. If you are on the cusp of the 2 sizes we would suggest you size down.
