I remember being told a story years ago about the lad from the Boys from Brazil film actually matching one of his pure Dobermans against a famous hare dog.The dobie lost of course but his owner smirked as he handed over the cash to the owner of the winning dog.When he walked away to his car with his dog and the bag of money the dobie owner just punched his fist into his hand and his dobie killed the man and his dog and retrieved the money to his owner(who was still smirking).The man who told me this had no reason to lie.
