Symptoms of Lung Cancer in Dogs

Persistent Cough

A persistent, dry cough that doesn’t go away can be one of the first signs of lung cancer in dogs. Unlike regular coughs or coughs related to kennel cough, this type of cough is persistent and does not improve with time.

Breathing Difficulties

Notice if your dog is experiencing difficulties breathing. This can include apparent effort with breathing, unusual sounds when breathing, or a significant increase in breathing rate. These symptoms can occur due to the growth of a tumor that might be pressing against the lungs or airways.

Lethargy and Loss of Appetite

Lung cancer can lead to a noticeable decrease in energy levels and a loss of appetite. If your dog suddenly seems uninterested in regular activities or stops eating, it's important to consult your veterinarian.

Unexplained Weight Loss

Weight loss that occurs without a change in diet or exercise routine can be another warning sign of lung cancer.
