There are numerous causes of lumps on a puppies skin. If Bella has been microchipped (this is usually done between the shoulder blades), it could be the chip you are feeling. Other causes are cysts, scar tissue, inflammation after a vaccine, and tumors. I would recommend taking Bella in to your local vet to have this lump evaluated. If it is her microchip, it is not a problem. If it is something else, your veterinarian can do a fine needle aspirate to try to get a sample of cells from this lump to determine what it is. This is not a painful procedure and similar to her getting a vaccine.
