I have 2 that are elderly - both of them I've had since they were puppies. Tigger, my Samoyed/Shepherd mix who looks like a small Samoyed, or Large American Eskimo (He weighs about 60 pounds), is 13. Bobo, who at best guess is some kind of Irish setter mix, is 12. I watch them age with trepidation - They're both doing dang well for their ages, but I see signs of slowing down more frequently. I know they're getting towards the end of their life expectancy, and treasure the days I have with them.
