Looks like you have a dog who is around you may be a pet. Make sure if it is a pet it's vaccination are uptodate.
I would suggest each of my patient with a dog bite to take vaccinations day 1 day 3 day 7 day 14 and day 28. If the dog can be watched, look out for change in behavior if normal till 10 day, first three doses enough other full schedule of 5 vaccination.
Next Steps
wash the bite site with savlon or dettol and lots of water. do not put any bandage.
