I would just keep what you are doing and keep an eye on it. It the skin is really flapping and you think it won't be able to grow back together get some butterfly tape. Its what they use instead of stiches sometimes, it just holds the skin together. Dunno if they sell it in the states though. If its not bleeding or anything I would just keep doing as our doing. If you are still nervous just call the vet and ask them what to do they will tell you over the phone.
