First of all, I don’t have a dog, but if I did and he were two years old, that would be equivalent to 14 humans years according to the old common converter. Snopes says that isn’t so. Instead, this chart from Antech is presented, with the fine print that small dog breeds tend to live longer and that no chart can cover all the bones.
By those numbers, my daughter had a Siamese that lived to 100. Most of mine have lived to between 76 and 88 years.
