#4 buckshot will kill the dog.
Pit bulls are great dogs. Pitt bull owners often are not great owners.
If you haven't called animal control, do so. You need to be on record that the animal is a danger to your property.
If you can, photograph the dog each time he comes on the property as another record.
You might want to try less lethal means of getting rid of the dog such as a bb gun or a cattle prod.
