He has what looks to be "flea dirt" in his fur but no fleas! He has had this off and on over the years, also with no sighted fleas. He is very overweight which we are trying to help him with, so he can't groom himself. I brush him every other day and he has quite a bit of white dander build up but the stuff that looks like flea dirt is not always there. It seems to build up on his back. Is it possible to have tons of flea dirt without having fleas? Could this be a dermatitis or parasite?

This could be due to different causes such as fleas, an allergy, an infection or mites. First of all, in order to rule out skin parasites, you will need to treat with a high quality flea treatment, then ask the vet to perform a skin scrape - this might reveal an infection or a mite infestation. If all of those came back negative, the next step is to treat the allergy symptomatically and try to discover the cause of the allergy. Three main type of allergies are usually affecting pets: food allergies, flea and parasite related ones and environmental type (allergens coming from trees, pollens, dust etc etc). Some medications can be given by the vet in order to repair any possible skin lesions (like steroids and antibiotics).
