How to Choose the Right Size K9 Mask® for your Dog
- If you do not have a flexible measuring tape you can use a shoe lace or phone charging cable to make your measurements. Then use a ruler or metal measuring tape to get the measurement.
- NOTE: If your dog is in between circumference sizes we recommend getting the larger size mask for better panting space in the mask.
