Welcome to the forum.
If I had to venture a guess, I'd think your person has a better idea of your breed than the shelter (which has a strong incentive not to call a dog a pit bull mix unless it's unavoidable, because they are more difficult to place). A bit more activity with your people may also help to show if the "full bodied" is innate, or just from a sedentary lifestyle.
