My oldest Collie Lassie turned 13 or 96 in dog years. I found a dog age calculator on the Pedigree web site. You type in the human age and the breed and it gives you the dog years.
My late lab, Chipper, lived to be 14.5 years old. The Pedigree site didn't go past age 13 for this breed. I guess he wasn't supposed to live that long - lol!
