We adopted an 8 year old shih tzu a week ago and since yesterday she has been haviing cough and trying to throw up but can't. What could cause that?

The pathogens causing this respiratory disease spread through the air, traveling from dog to dog very quickly and penetrating their respiratory tract with ease. Because of it, animals groups are very sensitive to this infection (canine residences, breeding grounds, dog contests and kennels).
In order to determine the stage of infection and treatment, you should take your dog to the veterinarian.
