Desmo the wonderdog. Faithful companion for 17 years. He has gone to doggie heaven, but will never be forgotten. Went every where,every day with me his whole life and never complained once.
Depending on how much space you have, and how active you are a Rhodesian Ridge Back might be a good choice. They are an awesome dog, loyal, friendly, and have almost none of the issues that other large dogs have (see: bloat and Hip/joint issues). The only issue is they are a little hard headed when they get older, so get one as a pup and train it then. Oh, and they come stock with a Mohawk...
