Agree, not full mini schnauzer, but certainly could have some mini schnauzer. To me, he is mini schnauzer size in comparison with the other dog. His legs look longer because they are trimmed close, but I do think he's definitely mixed with another breed. Totally just a guess, but I get some jack russell vibes with the shape/size of the snout and body frame.
Not a standard schnauzer imo, they are gurthier and just larger dogs in frame height and size.
