If your dog does have any fleas…that is enough to make them scratch like crazy. You do need to get the fleas under control. Just a few weeks ago, my niece was worried about her dog scratching and chewing like mad and I asked her “well does she have fleas?” “OH NO!” she says. She took her to the vet and the vet showed her that not only did she have fleas, she was crawling with them! OK so I have no idea how someone cannot see fleas on a small little dog but…Oh well…You can research some flea treatments at home but always be careful to research any “holistic” treatment for possible toxicity problems with dogs! There are a lot of people on line telling us they use this and that but be careful because dogs are sensitive to some of these things! Something simple you can use is bathe them well with some flea shampoo designed for dogs and you can sprinkle your carpet with boric acid…sweep in into the carpet and leave it for a while then vacuum it back up after a few days I think. Be sure and research how long to leave it because it’s been ages since I’ve done this. This is boric acid, not borax! You can find it at the dollar store sold for roach treatment. You will probably need a few bottles. This is safe and absolutely works like a charm! Do not put it on the dog!!!!!
