As this gameplay clip from Dead to Rights: Retribution shows, more games need the option to sic your dog on the bad guys.
After watching this clip, I'm of the belief that games that don't include dogs need to be redesigned in order to take advantage of today's canine attack technology. Imagine how much more enjoyable playing Rock Band online would be if you coud set loose packs of wild dogs on the opposing band. I'll just leave you with that lovely image.
Oh, and don't watch the video if you are under 18.
