Come and help me take care of the dog, thank you!

You should pay more attention. How old is your dog? You are right that it is coughing. I hope it is not pneumonia. Inflammation can cause viral infection. My dog ??was like this at the beginning. Later, I went to the pet hospital for a checkup and it was said that he had parvovirus. You'd better take him to have it checked out sooner rather than later. I really hope that your cough is just a cold. If it is a cold, your nose will be relatively wet. Please take a look.
