Thanks for writing to us.
You need to wash the area best with soap water and keep it open without applying any plaster/dressing.(I am answering this for a human bite as it is not clear in your history whether the dog has bitten you or another pet of yours??)
In addition you need to be immunised against Rabies(Eg Rabipur-Post Exposure Prophylaxis-0 day/03rd day/07 th day/14th day/28th day.) this is 05 dose course as per WHO recommendations.
Get immunised against tetanus
wishing you a speedy recovery.,
