These lumps look like they're subcutaneous, or under the skin. An abscess or other infection is possible, or they may be skin masses. They could be benign like a lipoma or fatty tumor, or may be something more serious like a sarcoma. I would recommend making an appointment with your veterinarian to have these lumps examined. Your veterinarian might want to take a sample using a small needle to examine under the microscope (called a fine needle aspirate).
