Sizing Chart - Ava Martingale Collar


Please provide a measurement using a measuring tape on your pup in standing position. Please use a current measurement. If you have a puppy growing up fast, we recommend you to buy a size larger.

Please note that these measurement already includes room for the limited-slip loop for the martingale collar and not the actual measurement of the interior room of the collar. If you want to provide extra room on top of that for your pup or if your pup is used to a looser fit, we will suggesting sizing up by 1".
