With any new lump or lump that is changing, it is always best to have your veterinarian look at them and a fine needle aspirated can be done to obtain a sample of cells. If these cells look suspicious of a malignancy, then your vet can recommend surgery. From the photos that you have posted, my guess is that these may be benign, non-cancerous masses. These can still cause problems, though, by bleeding and getting infected. I would schedule Max for an exam at your earliest convenience so that you and your vet can weigh the pros and cons of surgery since he is a senior.

That's a great question! Unfortunately, as pets age, lumps and bumps seem to occur more and more frequently. Bessie should be seen by your vet to have the lumps assessed and to form a treatment plan. Without further testing, there is no way to tell if these bumps are due to infection, trauma or allergy, or if they are masses. Masses can be of a malignant (cancerous) type that can spread elsewhere and/ or invade the healthy tissue around them, or a more benign (noncancerous) type that is unlikely to spread. Cancerous types of masses are less common than benign ones, but I recommend making an appointment for Bessie to see your vet to have the growths tested and to guide treatment. Your vet may want to do a fine needle aspirate, which is where cells are removed from the growth using a needle and sent to a lab to be examined under a microscope to determine what the lump is and to guide treatment. If the lumps are getting bigger, seem painful, or have any discharge or blood, please get Bessie to a vet right away. If she is licking at them, please put an e-collar (cone) on her to help reduce the risk of her injuring herself or causing infection.

Wow, that is quite large on Tiny! In a dog his age, I would be very concerned that is a malignant tumor. Unfortunately those can be common in senior dogs. This is something that needs to be seen by a vet as soon as possible, as if it's a malignant tumor, there is a good chance it can spread. It likely will also need to be removed surgically. Please take him into a vet first thing in the morning. Best of luck, I hope this helps!
