How Old is My Dog or Cat?

We all know that our pets age faster than us... but how much? The old "seven year" rule was simple, but does not really work beyond the first year. In addition, pets that are larger age faster. This chart, assembled from data available through the AAFP and IDEXX Labs, shows how old your pet is in dog or cat years, based on his or her weight.
