I use k9 advantix II on my 5lb chi but he's chewing on his butt. Can I use a flea spray on him, too...just his behind?

It would be okay to use something like Frontline spray along with Advantix but I would not use any other spray as it could cause toxicity. If you are still seeing live fleas you could ask your veterinarian about a medication to quickly kill the adults like Capstar. If there are scabs on Simon's behind he may have flea dermatitis and need antibiotics and/or a corticosteroid.
