My last dog had a severe flea allergy (in addition to everything else he was allergic to). He was on an oral flea preventative, which did not kill adult fleas but sterilized them so the eggs wouldn't hatch. Maybe once or twice a year, he would get a flea bite and chew a hot spot about 1-2" diameter. The hot spots very often took up to a month to heal, but spraying them with an itch-relief spray (PetRelief Anti-Itch brand) seemed to minimize the chewing and let the fur grow back more quickly.

The Advantage you are using actually kills adult fleas, but can take 4-12 hours before the flea dies. Plenty of time to bite and lay eggs, so you may have more eggs hatching soon. Vaccuum, vaccuum, vaccuum (and throw the bags out) and wash his bedding.

Dogs can develop an obsessive disorder and suffer from lick granuloma. I wouldn't worry about that right now. Sounds like a flea bite sensitivity. However you do want to stop him from chewing as best you can, so that he doesn't escalate to thinking that chewing on himself is a fun pastime.

Charlie occassionally licks his front paws to the point I think it's more than just grooming. I squirt some of the Itch-Relief spray on his feet and he stops.
