Q. My dog has bumps on his skin. We have combed with a flea comb, and there aren't any fleas, but he keeps scratching/biting/licking. What should we do?
A. Sometimes does have red bumps on their skin from flea bites. I would recommend seeing a veterinarian because it could be fleas but it could be something else. Maybe you're combing with the flea comb incorrectly, are you finding brown dirt like particles? Put that dirt like particles on a white paper towel and put water on it (Without losing the dirt). Smear the dirt and if it turns red that is flea dander. Flea dander is bowel movements from fleas and is digested blood. Your dog could also be suffering from other things such as mange, allergies or something else.
