Brian Griffin (Family Guy)

Brian Griffin, the martini-sipping, novel-writing canine from 'Family Guy,' is not your average pet. Toss him into the 'Greatest Fictional Pets of All Time' league and watch the fur fly. Fans are torn between loving his pseudo-intellectual rants and cringing at his failed romantic escapades. It's like, do we root for him, or do we root for him to get a clue? Either way, his blend of charm and chaos keeps everyone talking, and isn't that what a top contender does best?
