K9 Mask® Sizing Chart

The crucial measurement to determine the appropriate size is the Muzzle Circumference.
If a flexible measuring tape is unavailable, a shoelace or phone charging cable can serve as a makeshift alternative for taking measurements. Subsequently, use a ruler or a metal measuring tape to obtain the accurate Muzzle Circumference size.
In instances where your dog falls between two Muzzle Circumference sizes, we advise opting for the larger size mask. This choice provides additional panting space within the mask, ensuring both comfort and effective use for your dog.
