Good choice. For a dog like that you need a big name, something like Attila, Genghis, Stalin, Vlad (the impaler), Tyson, Hannibal etc.
If the he's at all clumsy and someone asks you what breed it is then say it's a Devon White. If he's a faithful terrier then call him Mackie. If the Koreans would love him (in a Tesco burger kinda way) then call him Park Ji Sung. Assuming he's not house trained, call him Bosingwa. Also, call his bollocks Taarabt cos he is the dog's and Queens will love it...
