Why is my heartworm positive Pomeranian having a dry cough lately?

Updated On September 23rd, 2025

Pet's info: Dog | Pomeranian | Male | unneutered | 5 lbs

Hello I have a question. I have a 7 year old Pomeranian and he has been coughing a lot the past few days. It sounds more like a dry cough like he may have something stuck or wants to vomit but nothing happens. It sometimes happens when he is running around and he starts coughing or when he wakes up. He tested positive for heart warms and is taking antibiotics right now.

If he is heartworm positive then the coughing is likely associated with it. Heartworms live in the pulmonary artery which is what takes the blood from the heart to the lungs to get oxygen. They can cause significant decrease in the amount of blood flow as well as they are really inflammatory. Their presence makes the lungs really angry and that causes cough. In later stages the heart can be so damaged that they can go into heart failure, which can also cause cough. I would highly encourage you to schedule a follow up appointment with your veterinarian to discuss this disease and how to treat it. I would also recommend an x-ray of the chest to see how much damage has already occurred. In the meantime I would encourage you to keep him on leash and not running around where he might cause more damage. Best of luck to you and Max! I hope he recovers well! Thank you for using Pet Coach.
