Based on your picture I think this looks like normal pigment, however sometimes dogs can start to get darker skin where they had a dermatitis that is resolving or a chronic skin issue. If the red spots are new or Jaxon seems itchy I would recommend taking him to your veterinarian to have them examine his skin.
