You should take him to the vet ASAP. There are hundreds of skin conditions that dogs can have, specially when they're pups (they want to investigate everything, and usually end up messing with dangerous stuff).
If he stratches it (which shouldn't happen, these thing will probably worsen), the vet will put him a cone collar, which will help to keep the wound safe during the treatment.
