Will the K9 Mask® Work as a Muzzle for My Dog?

  • While the K9 Mask® can function as a muzzle, its primary purpose is to shield your dog from air pollution.

K9 Mask® Air Filters are Independently Verified for Effectiveness?

  • K9 Mask® air filters have been certified by Blue Heaven Technologies in Louisville, Kentucky, USA with an ISO 16890 air filter test.
  • We do not use the term N95 for K9 Mask® air filters because this term has been trademarked by the USA CDC but they provide the same level of effectiveness as N95 rated air filters.

How to Insert the Air Filter into the K9 Mask®.

Open the zipper on the top of the mask. Insert the air filter into mask with the dark side on top and white side on the bottom. Place the curve edge of the filter facing the nose of the mask. Align the air filter inside the mask so all edges of the air filter fit against the sides of the mask. Close the zipper on the mask.

How to Secure the K9 Mask® on a Dog's Muzzle to Keep Polluted Air from Being Inhaled.

K9 Masks® are effective when they are worn properly. Using the K9 Mask® muzzle adjustment under the snout of a dog a pet owner is able to adjust the tension on the mask to significantly reduce polluted air from leaking into the mask. This ensures only air passing through the air filter is being inhaled by the dog.

How Do I Train My Dog to Wear the K9 Mask®?

Training your dog to wear the K9 Mask® involves pairing a positive stimulus with wearing the mask.

  • Present the mask to your dog and let the dog smell it.
  • Try adding a snack treat inside the mask for your dog to sniff and retrieve. This process gives a positive reinforcement about the mask.
  • Try putting the mask on your dog’s muzzle for a few seconds, while giving verbal affirmation to your dog, to acclimate it to the mask.
  • Repeat this sequence several times, working towards securing the mask in place around the dog’s neck and muzzle using the hook and loop tabs.
  • Provide positive verbal feedback to the dog about wearing the mask.

How Long Can My Dog Wear the K9 Mask® Using a 95 PM2.5 Air Filter?

  • Prolonged use can affect a dog's natural ability to cool itself through panting especially at temperatures of 80°(F) 26°(C) or higher.
  • The K9 Mask® with an Extreme Breathe filter is intended to be used for a short duration and under close supervision. Be cautious using for more than 10 minutes at a time. After 10 minutes you may remove the mask for several minutes to check the breathing and panting of your dog then continue wearing the K9 Mask®.
  • The K9 Mask® with a Clean Breathe filter can be worn for 30 minutes at a time. After 30 minutes you may remove the mask for several minutes to check the breathing and panting of your dog then continue wearing the K9 Mask®.
  • Always visually monitor your dog while wearing the K9 Mask®. If you notice labored breathing or signs of overheating remove the mask immediately. This mask may cause injury or death to your dog.

How to Choose the Right Size K9 Mask® for a Dog

K9 Mask® Sizing Chart Fit Guide for Dog Air Filter Face Gas Mask
    • 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.

    Caring for Your K9 Mask®

    The exterior mask is designed to be washable, recognizing that dogs may slobber while breathing or panting. This feature ensures the K9 Mask® stays fresh and clean for extended use.

    However, please note that the replaceable air filters, which can be easily removed from the mask, are not washable. Before washing the K9 Mask®, it's essential to remove the air filter.

    To clean the exterior mask, follow these steps:

    • Remove the air filter from the mask.
    • Wash the exterior mask in cold water using detergent.
    • Hang the mask to air dry.

    This simple routine helps maintain the hygiene of the K9 Mask® and ensures a comfortable and clean experience for your furry companion during every use.
