Most dogleg jacks are 3 1/2 inches long and are obviously deeper in the body - they're a chunky pattern. I had a dogleg jack that was 3 3/4 inches once, but that was unusual (CRS is preventing me from remembering who made it).
No, a dogleg jack does not have it's blades at the large end -- you do that and it becomes a wharncliffe die knife of some sort.
