Dog bite on the thigh, very minute.

Couple of months ago, a dog on the street tried to bite me but it backed away immediately. It led to a small round wound on my left thigh, just one mark, it didn't land all its teeth on me, just one tooth was landed and retracted immediately. I washed the wound after 20 minutes with Dettol liquid multiple times and allowed it to heal. Its more than 2 months now and the wound never bothered me, it healed almost completely, there is just a small dark spot in its place. Although I'm now concerned with the possibility of acquiring any infections due to the bite(not sure if it can be called a bite) as the bite did cut the skin. The dog which bit me sleeps in the same place every day, I can recognize it too, if that's any useful info. Please let me know what I can do to make sure I didn't acquire any harmful viruses or infections from the incident.
