Swamp cooler harness for mini dachshund

Absolutely love the swamp cooler harness for my long haired miniature dachshund. Some mornings the temps are still on the warmer side and I soak the harness in water before we head out. I’ve noticed that she stays cooler with this harness than if I use her regular flagline harness (not panting as much or stopping as much). We only go out in the early mornings on the really hot days to help avoid heat stroke. But there are still mornings where we really need that extra cooling the swamp cooler provides. Especially since my girl’s coat is black and tends to absorb all that radiant heat a bit more easily. The XXS is the perfect fit for her and I’m super glad it’s made that small. Love it!

Great harness

Keeps our staffy cool when it gets above 25 degrees. Real life saver in the Aussie summer. Make sure you bring enough water in case it dries up while on your walk. Only minor issue is that it gets dirty quite quick but that’s to be expected
