Dog has a bump near his lung. Should I worry about a punctured lung?

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.

This looks like either a mass or an infection. I would recommend taking Tiny in to his regular vet clinic as soon as possible (but no need to go to the emergency clinic). They will likely sample the growth (no sedation required) and look at it under a microscope to decide what to do next. Surgical removal may be needed. If they aren't sure if it's an infected mass or just an infection, they might treat with oral antibiotics for a few days before deciding about surgery. Good luck!

Having a cough when excited would make me concerned that her heart or lungs are not functioning correctly. It could something as mild as a lingering infection or as severe as lung cancer or heart failure. In terms of the lumps and bumps, those sound like masses, which could be cancerous or benign. She needs to go to the vet for an exam and chest x-rays, and then the masses can be sampled to determine if they are concerning once you know how severe the issue in her chest is. Hoping you get some good news.

No, it's not normal when it appears a dog is having trouble breathing. That is a medical emergency, as it can quickly lead to respiratory distress. I'd take Ice into a vet now to get checked out as I can't see him in person to know if he will be ok or not. Best of luck.

As long as she is otherwise acting ok, it is not growing rapidly, and/or has a discharge then you could wait and take her this weekend. Your vet can do a needle aspirate to help determine the cause and determine if the lump needs to be removed or treated.

This could simply be a benign tumor, but it a dog Tucker's age, there is a chance it could be malignant. Any suspicious lumps should be examined by the vet. The vet can perform a test called a fine needle aspirate on it. To do this, the vet sticks a small needle into the lump to get a sample of its cells, and examines the cells on a slide under a microscope. It's usually painless to the animal, and relatively quick to perform. Once the cause of the lump is diagnosed, the vet can discuss treatment options if needed. Give his vet a call to make him an appointment. Best of luck.

There are a couple of things this lump could be on Titan. It could be a cyst, an access, a lipoma, a benign tumor, or a malignant tumor. Any suspicious lumps should be examined by the vet. The vet can perform a test called a fine needle aspirate on it. To do this, the vet sticks a small needle into the lump to get a sample of it's cells, and examines the cells on a slide under a microscope. It's usually painless to the animal, and relatively quick to perform. I would have Titan seen by a vet today or tomorrow to have the lump examined and diagnosed so it can be treated if needed.
