Using this dog coat is easy. Just put it on your dog and adjust the chest and belly straps for a snug fit. Make sure the hook - and - loop closure is secure. When it comes to care, remember to use a dry brush to remove dirt regularly. If it gets really dirty, wash it with water only and let it air - dry. Don't use any harsh detergents as they may damage the oilskin. To deal with sweat and bad smells, a mixture of 1/3 vinegar and water works great. Once a year, apply our Duck back wax to the coat. This will help maintain its waterproof property, keeping your dog dry in wet weather.
