I didn’t actually purchase this for the cooling effect but instead for the full body support it would offer our mini schnauzer whose back legs need assistance. I can clip her lead in and feed it though to the handle to hold up her front and back without too much pressure being on a certain part of her chest. She has a lump on her chest (was removed and is coming back) that her old harness dug into it if we used it to support her so this harness ticks all the boxes.
She now looks very cool in her support system!
The XS fit her perfectly with the straps almost as tight they can go and because they clip both sides, she doesn’t have to hold any of her legs up to get it on so it keeps her stable. Perfect for an old dog with wobbly legs!
