I don't have an old dog, but we have three old cats. They are all "senior citizens" now. We've had Ben since he was 4, but Henry and Oscar have been with me (and now us) since they were kittens. I would definitely consider adopting an older pet if the opportunity arose. I know that shelters always have older pets who don't find homes as quickly as the younger pets.
Do you have aging or old pets? Have you ever adopted an older pet?
