Using this cooling dog coat is easy. First, soak the coat in water and then squeeze out the extra water. Put it on your dog, and it'll start keeping them cool right away. Remember, the coat will stay cool as long as it's damp. The cooling effect may vary depending on your dog's body heat and the outdoor conditions. If the weather is extremely hot and dry, you may need to re - wet the coat more often. To maintain the coat, simply wash it with mild detergent after use and let it air dry. Avoid using harsh chemicals as they may damage the cooling properties of the coat. Keep it in a cool, dry place when not in use.
