What makes Kumfy Koatz unique from other dog apparel/harnesses?
Kumfy Koatz is the first thermal harness designed to use proven gel bag technology. Each product includes a Kumfy Pax, which can be heated and/or cooled.

Why does the pouch for the Kumfy Pax cover my dog’s chest area and not the top or side?
Research shows that canine physiology is very important when trying to regulate a dog's body temperature, and the core must be addressed.

Is the Kumfy Pax gel safe if my dog chews it?

The gel in the Kumfy Pax is non-toxic, however, should NOT be ingested. If the gel bag becomes punctured, please discard it.

How do I know if the Kumfy Pax is too hot after I microwave it? 

After microwaving it (directions are printed on Kumfy Pax) quickly touch it to determine if it is scalding anywhere. If it is too hot to touch let it cool until you can. It should be warm so it will penetrate the fabric and the pet's fur but not too hot. The user is responsible for determining the appropriate temperature before use.

How do I cool the Kumfy Pax?

Lay the Kumfy Pax flat in your freezer for at least an hour. After you remove it from the freezer, massage the gel to evenly distribute it before placing it in the Kumfy Koatz pouch.

How long will the Kumfy Pax maintain desired temperature?

Temperature maintenance will depend on the size of the Kumfy Pax and outside temperatures.

Can I use the Kumfy Pax more than once?

Yes. Kumfy Pax are reusable and replaceable. We recommend keeping two on hand so you can keep one in the freezer and one at room temperature.

How do I know what size will fit my dog?

All products are based on the measurements from the base of the neck to the tail, and the neck and chest circumference. Please see the size chart.

How do I clean my Kumfy Koatz?

Remove Kumfy Pax before washing. The harness can be hand washed with cold water and mild detergent. Hang dry.

Can I use the harness without the Kumfy Pax?

Yes, the harness has been designed to use with or without the Kumfy Pax.
