    Bird Dog Cool

    Recent purchase for my English Pointer. Between hours at horse farms and shows and running in the fields for birds this is working to keep her cooler. I notice that her panting recovery is way faster. She likes sunbathing in 90 degree heat so this makes me happier! It gets very dirt when wet.

    Very good for extreme heat

    Jasper, a very active Parson Russell Terrier, 7.7 kg he wears XXS in any of the harnesses. He has them all for different times I just wish they could clean better.

    Game changer for summer

    The swamp cooler harness has been a game changer for my husky in the warmer seasons. He loves hiking and going for runs but as soon as the weather changes and it’s sunny it is too hot for him. Wearing the swamp cooler harness he has loads of energy and is able to enjoy his hikes. I want to get one for his Labrador brother next.

    Perfect for my new dog!

    I rescued a new dog. He has an undercoat and lived his life tied up outside. He does not do well in the heat so I decided to try this harness. Its perfect for summertime walks!

    A real help

    It seems to work really well. The vital organs are cool, so the body can focus on the rest of the body and try to regulate the temperature in the rest of the body.

    I was able to do my walk normally, without him stopping all the time or looking distressed. He seems more than thrilled anyway.

    To be seen when using but I validate.
