This Dog And Human Years Graph helps to explain our pets age to our own human years.
From Wikipedia, the free encyclopedia
SummaryGraph of dog age to human age. There is no single authoritative and generally agreed graph, but this should be close. Data for ages 5 and higher is taken from Table on dogpack.com, said to be "based on a chart developed by Fred L. Metzger, DVM, Dipl. ABVP; State College, PA". Data for ages 0-2 is taken from numerous sources that cite equivalent ages for 1 and 2 year old dogs (other than giant breeds). Data for giant breeds under 2 is the same data, but reduced slightly to allow for reports in many websites that such breeds mature more slowly Data for ages 2 - 5 is simple linear interpolation, as most sites agree a linear model is valid even if they disagree on the exact ratio of years to be used. Breaks at 2 and 5 years mark the above for completeness. The standard for human survival is not disclosed but appears to assume a human lifespan of around 77 - 80 years as its comparative.
