How old was your longest living dog?

Lady was our oldest lived dog. She belonged to my Grandpa, not to myself though. He had taken her in as nearly an adult dog in exchange for some work he did on a log table saw.

She's been gone now many years, but looking back through family pictures, she spans through 19 years worth so given her adult status when they took her in she had to be nearly 20 or perhaps moreso.

She was quite an undetermined breed. I'll have to pull out some photo albums to see if I can get a picture of a photo I may have of her here yet. She was always present so I'm sure I'll find a good one.
