This could be a severely abscessed anal gland/sac or a tumor or a perineal hernia. This can only be diagnosed with a hands-on exam. You should have it examined by your veterinarian, as it is not possible to distinguish these by just looking at a photo. An abscess can usually be treated with antibiotics and/or be lanced, and a hernia may have to be fixed surgically. To identify a tumor, 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.
