My dog's cough returned. What causes it? Is it heartworm disease?

Hello, there are multiple causes for a cough like the one you are describing. One potential cause may include heartworm disease, however, this can be checked with a snap test. If it returns positive for heartworm, then there are medications you can try at home to treat this disease. Other causes may include heart disease and lung disease. Some primary lung diseases such as bronchitis and pneumonia can cause this. To fully explore this causes for your dog's cough, he may need x-rays, a cardiology consultation, and a heart worm test. The other cause in smaller dogs include a collapsing trachea. Ideally your coughing dog should not live an fast or active lifestyle to prevent exacerbation of her cough and from her going into respiratory distress. Please see your veterinarian soon if your dog continues to cough. Hope this helps and best of luck.

Heart worms can be detected through a blood test that can be done at a veterinarian’s office. Heart worms are transmitted by mosquitoes...a mosquito harboring a life stage of the heartworm will transmit it to a dog by biting it. It is not passed from dog to dog through casual contact. Heartworm disease is easily prevented, so if your veterinarian can test your dog and he is negative....there are a number of heartworm preventative products available through your veterinarian.

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.

Thanks for using Petco Pet Education Center, formerly Petcoach! Besides being due to heartworms, coughing can be a sign of many conditions such as pneumonia, bronchitis, heart disease, among many other possibilities. I recommend that you have Scooby evaluated by your veterinarian for further assessment and treatment. Likely diagnostics to be performed include thoracic radiographs and bloodwork. Treatment would be dependent on findings. Good luck and have a good night!

This cough could be due to heartworms, especially if your dog isn't up to date on his heartworm treatments, but it could also be due to cardiac disease, respiratory disease, or kennel cough. Given that he has been gagging and hacking for about a week, I would have him seen by a vet tomorrow. The vet can diagnose what is causing his symptoms, and can discuss treatment options with you.

Thank you for submitting your question regarding your dog. Most of the time if a dog is coughing up a white foamy material, an upper respiratory tract infection is to blame. This is similar to a human cold and be acquired anywhere. There are a variety of viral and bacterial causes. Heartworm disease can cause a dog to cough in advanced cases. This is usually a non-productive cough though. I hope this information helps!

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! I would assume if Danny has something infectious like a bacterial or viral pneumonia he would have improved with antibiotics or the virus would have ran it's course. The only advice in retrospect would have been to not stop the antibiotic until the cough had resolved for at least a week or 2. Some pneumonia's require 4-8 weeks of antibiotics. He definitely could have something else going on in his lungs like heart worm, heart disease, tracheal disease, a hernia, fungal pneumonia (they are very sick), cancer or allergic airway disease. If you are able try to get Danny to a vet for an exam, heart worm test and chest X-rays. I wish you the best!
