I have an Eskimo Sled dog mix, he was born not very far from the Arctic circle, it’s really an under statement to say he doesn’t do well in the summer heat… this little piece of cloth makes a huge difference. We soak it in a cool stream every two or three hours and my dog is moving again. We’ve even taken him hiking in the Canadian Rockies in 30 degree celsius and he was still happy. It’s now an essential part of his hiking gear.
