Hi there. Archie is very cute! He's old enough to be started on a prescription flea medication like Nexgard, so I would recommend taking him in for a check-up with your veterinarian. He/she can prescribe an appropriate flea treatment for him to get rid of the fleas and make sure he doesn't pick up any more.
