Lung infection or cancer? 4-year-old dog

Thanks for reaching out with your concerns about your four-year-old dog. I know how worrying it can be to see potential health issues in our furry friends. Let’s go through some potential causes for what might be happening and how to proceed.



With lung infections or cancer, dogs might show similar symptoms like coughing, difficulty breathing, lethargy, or weight loss. Lung infections, often caused by bacteria, viruses, or fungi, can lead to respiratory distress but usually respond well to appropriate treatment. Cancer, on the other hand, might cause similar signs but can be trickier to manage and requires specific treatments.



At home, you can help by ensuring your dog gets plenty of rest, keeping the environment calm and quiet, and encouraging hydration. Monitor their breathing—if it becomes labored, or if you notice rapid changes in behavior or energy levels, it's important to seek veterinary attention immediately.



Signs to watch for that indicate a more serious issue include persistent cough, wheezing, a noticeable drop in appetite, or cyanosis (bluish gums or tongue). If you observe any of these, or if your dog seems to be in distress, please consult with a veterinarian as soon as possible.



I recommend setting up a video consultation with one of our vets here at Dial A Vet to get more tailored advice and determine the next best steps for your pup's health.
