The Cool-Coat will make your dog feel cool, not wet. You can test this by putting your hand beneath the dogs coat & feeling how cool he feels compared to any part of his coat that is exposed to the sun or heat for a period of time. As the heat of the day slowly evaporates the moisture from the Cool-Coat, this in turn draws the heat out of the dogs body. Leaving him feeling far cooler than before. When your Cool-Coat coat starts to dry out, it will begin to go back to its natural state, becoming slightly dryer, & a little stiff. When this happens, simply re activate your coat by putting it in water. Immersing the Cool-Coat in water for just a couple of minutes. Once the Cool-Coat is completely saturated, remove the coat & squeeze out the excess water, so your coat feels cool, yet not wet. To clean your Cool-Coat, wash through thoroughly in clean water, if really dirty, it is safe to put your Cool-Coat through the washing machine. Please remember to Always wash your dark colours separately. To store, simply allow your coat to dry & pack away. Our Cool-Coats are made from 100% synthetic material, they are simple to use, wash & store. Size Guide For the most accurate fit it is recommended you measure your dog from by the base of the neck to the base of the tail. Ensure your dog is standing squarely with the head up while measuring. With your dog looking ahead, measure from the point where the neck joins the body to the point where the tail joins the body. Below is an approximate sizing guide based on breed, but we highly recommend you measure your dog for the best fitting coat. Size Guide Fits Breed 10 inch/25cm..
