Since the dog has a cold, it is imperative to deal with its cold problem. It can't catch cold any more. It needs to prepare quilts, warm water bags and other heating supplies to cover it, or give the dog some warm water to warm up. Some dogs are in good health. Take a rest in a warm place and you will be fine. But if it continues to sneeze with a runny nose, it is necessary to give it some warm-keeping products for dogs to eat and feed it. Some dogs catch a cold, which is not caused by a cold, but by a virus. Therefore, it is necessary to do a good job in indoor hygiene, disinfect the dog's belongings and try to keep the room clean and tidy.
