K9 Mask® Size Chart

K9 Mask protects dogs from smoke, dust, ash, toxins, chemicals, bacteria, and smog

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.
