I would say #4 but not knowing the weight of the dog it is hard to say. Many dogs that carry the name APBT are not true to the breed. Many dogs being called APBT weigh in at 100+ pounds when the breed standard until recently was 35-50 pound range. The dog that has evolved has a lot mastiff in its bloodline. If you want to see what a APBT should look like see a Staffordshire Bull Terrier as a standard.
