The standard converson of 7 year equivalent to 1 year and thereafter has been around since the 1950’s. On the average, smaller dogs tend to have longer lifespans than larger dogs. Based on that, the 7 year conversion method is questionable because it doesn’t take that important factor into account. This chart from the AKC takes professional studies of longevity into account. So… How old is your dog???
