The Ruffwear Swamp Cooler provides protection from the sun and cooling through evaporation. In warm climates, dogs typically stay cool by seeking shade during the heat of the day and moving around in cooler temperatures. The Swamp Cooler allows dogs to perform in hot climates. To activate the Swamp Cooler, soak in water, wring out and place on your dog. The light-colored fabric reflects solar radiation, while evaporative cooling pulls heat from the dog. The integrated leash portal allows leash attachment when the Swamp Cooler is worn over our Front Range™, Hi & Light™ or Web Master™ Harnesses.

Keeping black dog cool on SoCal

Bought this after moving to San Diego as our black lab always got hot even for early morning hikes. Seemed to help keep his body cooler so we could do longer morning hikes.

Does Not Work!

I purchased the Swamp Cooler thinking it would help my Great Dane during summer months, since we live in Palm Springs, CA. Usual summer day 120° nightime between 95° - 105°. It did not help Grunt in anyway. It actually made him hotter. I tried different temps. of cold water, ice cold, refridgerated and cold out of tap. It stayed "cool" for about 5 mins. Material construction was great. Obviously, not engineered enough for a 175lb Great Dane.

Best cooling vest review from Michi the happy Bouvier

I love my best since I can still take long walks in hot weather. I am in favor of really cold weather since I am a big fluffy Bouvier. My mom brings ice water for me to drink but as my best dries, she can pour more water on the vest and it regenerates its cooling abilities. This vest saved me from a long boring summer. You can see me in my vest on Instagram. I love the designers at Ruffwear. Michi the happy Bouvier

Great product

We were very happy with this vest to keep our pup cool as we hiked in humid, hot conditions in August. She was quite comfortable in it with minimal panting. The only issue we had was that while she has big lungs (greyhound), she's skinny across the chest so the vest rubbed on the interior of her legs some. Tying that together a bit more should fix it in the future, but a word of caution for pups that are deep barrel chest with narrow hip/shoulder width.
