The earlier comment is correct, I would say, that the article suffers by only using images of APBT's.  Using an image of another breed in addition would clarify that "Pit Bull" refers not to a specific breed but to a group. My preference would be to replace the second image on the page with the top image from the Bull Terrier page: [] because the profile makes it clear that it is a different breed.  An appropriate caption would be "An English Bull Terrier, another breed often termed 'pit bull.' "
