Older dogs are not common, but not totally out of the question either. For instance every once in a while we hold back more than one puppy from a litter to evaluate as breeding dogs and after we make our choice let the other one(s) go. Or sometimes one of us will have a leftover puppy for one reason or another which will end up as a started dog. If you are willing to wait a while you can eventually find one, especially if you’re not super picky about color or specific looks.
