Yes it can be normal for older dogs to develop certain benign skin lesions/masses. Common benign dermal growths are sebaceous cysts, papillomas (warts), skin tags, and lipomas (fatty tumors).
All new lumps should be evaluated by your veterinarian. Most lumps should have a fine needle aspirate performed to collect cells for identification under the microscope. Lumps that are identified as malignant should be removed. There are indications for removing benign lumps as well.
Talk to your veterinarian more specifically about your dogs lumps. Make sure they are keeping record of each lump. You can also start a chart as home as well.
