I've heard an average of about 12 years. Heredity and diet can make a big difference. I had a yellow lab who died pretty suddenly at 10, but I know someone with a lab that is 18 years old. My current black lab is a rescue, so I don't know his age.
A given DNA lab can only take in so much work at a time. The biggest limitations are staff, space, and machines. How long does it take to actually process a DNA case after it's been started? A lab that can do it in 30 days is doing a great job. 60 days is acceptable.
