All dogs except large dogs and polar sled dogs are afraid of the cold and all puppies are afraid of the cold. Puppies should be kept indoors until they are three months old, taking care not to let them lie on cool ground for long periods of time, and the litter should be lined with thicker cotton stuff. You can place a hot water bag in the nest, which should be wrapped in a towel. Let it move around indoors, do not give it a bath, it is easy to catch a cold and will make the dog’s health worse in the future
