Dog bite are common overseas, so should I get rabies shots pre-travel?

No. This is unnecessary and not typically advised unless you are planning on being in very close contact with non- domesticated dogs.
Not necessary. Rabies shots are indicated after an animal bite and not for prevention of a possibility. This would not be an appropriate shot to receive prior to your travel.
No. Rabies shots have significant side effects so they should only be done if the dog or animal that bit you has evidence of rabies or is likely to have had rabies.
