World's Oldest Dog?

The oldest dog in the world, according to the Guinness Book of World Records, is British Dachshund Terrier cross breed Otto Jones. He is twenty years and eight months old, and apart from a little arthritis and some grey hairs, there is nothing that shows he is very old.

I would like to be old myself, as long as I am as healthy as can be. Shiba Inus can get really old, though I have not heard of any who became twenty years old.

It should be noted that while this dog is a cross breed, there is nothing that says that other Dachshund Terrier cross breeds will be as long lived as he is. I do not even know what Terrier breeds are in him. He must have hit a jackpot in the genetic lottery.
