Hi there. The black grit you are describing sounds like it may be flea dirt (flea poop), and the base of the tail is a common area to see this if your dog has fleas. So I would be concerned that Jackson may have picked some up. I would recommend getting him started on a good quality flea control medication like Nexgard or Bravecto - you can get these from your veterinarian, or order them online with a prescription from your vet.
