This is very concerning and I recommend to have your pup checked out as soon as you can. Shortness of breath is very concerning for fluid building up in the lungs (which can be due to several causes including heart disease and cancer). A primary lung disease, a tumor in the chest, lung parasites or a problem with the diaphragm. Dogs don't really get asthma like humans do. They can get a bronchitis but this generally presents as coughing and wheezing. It's best to play it safe. The veterinarian will need to listen to the heart and lungs, conduct a physical exam and may need some radiographs. This is the best way to figure out the cause and to know the best treatments available. I hope your pup start feeling better quickly and please feel free to post any additional questions.
