It sounds like its not a problem, no bleeding even. All you need to do is wash the areas and keep an eye on him to make sure there’s no infection (not that you should expect any in this case). If it starts to look red or puffy, it needs to be treated.
If there are any punture wounds you should see a vet. Examine him closely, sometimes they are elusive & do not bleed. If untreated many punture wounds abcess. Clean the areas with hydrogen peroxide & if you like use some neosporin. Just keep an eye on him & if there are any swellings make an appointment with your vet. :O)
