What do i do if my 3 yr old son got bit on the arm by the family dog?

Dog Bite: Bite by family dog who has had his shots, you need to clean the wound and most of the times depending on the size and location of bite needs prophylactis antibiotics to prevent infection.Make sure your child has had all his baby shots including tetanus vaccine.

First make sure...: ...That the dog's rabies immunizations are up to date. If your son has not had a tetanus shot recently, he needs one. The wound needs to be thoroughly cleaned. There is no need for antibiotics unless an infection is present, or thought to be very likely to occur.
