Rain coats are not really necessary for dogs. Rain coats and other articles of dog clothing have really become accessories for dogs. Rain coats can be used as fashion accessories, but they can also be used to keep your dog dry while walking. So, if you walk your dog regularly even if it rains then you may want him to wear a rain coat especially if the temperatures are cool outside. In the summer, however, when it's 90 degrees out and raining, your dog will be just fine without a rain coat. In fact, the rain coat could make him overly hot and even sick. Smaller dogs or hairless dogs may benefit from a rain coat simply because they don’t have a fur coat to protect their skin or keep them warm. When looking for a rain coat, make sure the size fits your dog’s weight and not necessarily breed. Try the coat on him before buying. If you need help with sizing, ask your most pupular veterinary clinic Des Moines IA.
