Frequently Asked Questions
How do evaporative cooling vests work and are they safe?
Evaporative vests are soaked in water, wrung out, and fitted to the dog. As the water evaporates from the vest’s absorbent layer, it draws heat away from the dog's body. They are safe when used as directed — avoid leaving a soaked vest on a dog in extremely humid conditions where evaporation is slow, and monitor your pet for discomfort from prolonged wetness.
How should I measure my dog for a cooling harness?
Measure your dog’s girth: wrap a flexible tape measure behind the front legs around the widest part of the ribcage. Most vest harnesses are sized by girth. If your dog is between sizes, choose the larger size for comfort and adjustability.
Can cooling harnesses replace shade and water?
No. Cooling harnesses help reduce surface temperature or increase airflow, but they are not a substitute for shade, fresh drinking water, and limiting activity in extreme heat. Use a cooling harness as one part of a broader heat-management plan.
