Pets can itch for many reasons. Trifexis is generally a very good product so fleas are unlikely though you can certainly check him with a flea comb. Pets can develop dry skin or allergies which can all cause itching. I recommend to have Buster examined by his veterinarian to start figuring out the cause and to get medication to help stop the itching. You can try adding in an omega 3 fatty acid supplement for dogs, this can help improve the skin health. You may also try changing his diet to something like Royal Canin or Nutro as they are aimed at skin health. I hope this helps.
