This may be a pimple (little abscess), cyst or a tumor. . An abscess can usually be treated with antibiotics and/or be lanced, and a cyst can be evacuated. Your vet may want to do a fine needle aspirate (he takes some material from the bump with a needle and then looks at it under the microscope) to determine whether the mass is concerning. This may also just be a wart. You can observe this for a week or two and if it does not grow, just keep an eye on it. If it grows, take your dog to your vet for an exam.
