Why is my senior dog lethargic, breathing hard, and has a chest lump?

I know it can be scary when thinking about possible cancerous masses in your pet. But really the only way to know for sure is to have these masses tested through your vet. They can be cancerous masses, inflammatory reactions or benign tumors (non-cancerous). The heavy breathing that Allie is doing does concern me a bit. This can either be a sign of pain or an underlying lung or heart disease. So a vet visit although no desired, is probably the bext best thing to do for Allie in figuring out what's going on with both concerns. Best of luck getting some answers and take care.

Hello, I am sorry to hear about Dante. I would recommend having Dante seen by your veterinarian so that they can perform an examination and diagnostic workup. It is possible that the rash is due to a skin infection, but these often do not make dogs systemically I’ll, so I am concerned that something else could be going on. Your veterinarian may recommend bloodwork and taking X-rays to look for possible causes of his symptoms. The coughing that you are seeing could be a sign that Dante has pneumonia which can cause lethargy, inappetance and fever. Hope this helps, good luck!

These are alarming symptoms indeed. For an older dog with coughing and lethargy, my top suspicions would be: heart disease, heartworm disease (if he is not current on heartworm prevention) primary lung cancer, pneumonia or a heart based tumor. He is at risk for all of these based on his breed. I would highly recommend taking him in to your vet for bloodwork analysis and chest radiographs to properly diagnose him based on the many possible causes stated above. Poor guy. He sounds very unstable for now and the quicker you can get him in to a vet the better. I hope that this is something you can treat for, but the odds of it being something major are high in an older large breed dog. I send you all my best in getting Casper well again. Take care and best wishes.

It can be very difficult to evaluate x-rays without being on the computer that took them - I can't manipulate the lightness and darkness or zoom in all the way. That being said, I am concerned that there is something very serious going on in Jasmine's liver. It is much, much larger than in a normal dog. I can't see the entire spleen, but the parts that I see appear normal. I can also see that there is some free fluid in her chest cavity - this would be fluid between the lungs and chest wall that can cause trouble breathing. I would recommend re-evaluation immediately with an emergency vet. There could be many things going on, but the heavy breathing you described combined with the abnormalities in the chest have me worried that she may be having severe issues with breathing. This can cause severe anxiety and stress in a dog. The vet will probably want to repeat the x-rays and bloodwork, and may be able to draw off fluid if it is still there to ease her breathing.

Poor guy! In a senior dog, I would be very concerned that his huge bump is a malignant tumor that has now spread to his lungs causing his problems with breathing. Cancer can also affect his walking. I would have him seen by a vet right away. This bump needs to be diagnosed with a fine needle aspirate to see if he does have a malignant tumor, and x-rays need to be done of his chest to see his heart and lungs. Once the cause of this bump and difficulty breathing and walking is diagnosed, the vet can discuss if there are any treatment options for him.

How does a vet have no equipment to examine the dog? If that vet did not know what is going after looking at the dog I'm not sure how much I can tell you over the internet without looking at the dog. The most I can tell you is that at 14 years old this is likely cancer and you are not going to be able to fix it. I suggest you take him to another vet that does have equipment so you can try to get a diagnosis. A biopsy of the tumors are needed. If it is cancer it may have spread to his lungs and that is why is not able to breathe well. If you cannot afford to do all the testing to figure out what is happening then you may need to make the decision to euthanize him as it sounds like he is suffering and in pain. Please take him to another vet to get this sorted out.

Hi. It sounds like he is having respiratory signs. This could be from many things such as....upper respiratory infection, cardiac disease, primary respiratory disease, cancers, or other infectious causes. With his age, he needs a full exam, labs, and chest x-rays. If he is in respiratory distress, you will want to go to the ER.
