Generally speaking, puppies before 3 months old cannot be bathed. If symptoms such as runny nose and lack of energy appear after bathing, the owner is best to measure the dog's temperature. If there is repeated high fever, it needs to be sent to the hospital in time. Go to a pet hospital for treatment. If it is mild, you can also buy cold medicine on your own. It is also best to buy canine distemper test strips for testing to avoid developing into a serious disease.
