Welcome to healthcaremagic.
If you are sure that the two little holes could be due to a snake bite
then taking him to ER soon would be a better idea.
The wound weeping also makes me suspicious of a continuous reaction going around which could be due to snake antigen too.
I would ask you to give him a dose of antihistaminic like Benadryl
which reduces the reaction there.Benadryl will help no matter it is due to snake bite or any other material.
Wish you good health.
