Are you having trouble getting your dog to go outside to do his business? Despite being covered head to paw in fur, dogs do get cold in the winter! You may not know, but a dogs under belly has much less hair and therefore needs to be protected against the cold. Breeds with short coats, like Chihuahua’s, Greyhounds, Weimaraners and Whippets etc. will benefit from wearing a coat during a frigid stroll around the neighborhood.
