Dogs do not get rashes from Lyme disease infection like people do. So, it is highly unlikely to have anything to do with Lyme disease. This looks more like just a mild skin infection/scrape. You can apply a thin layer of Neosporin to it twice a day. If after 7 days or so it does not seem to be healing you should have your vet take a look.
