Calculate Your Dog's Age

Fiction! Canine aging is actually much more rapid in the first two years of its life. After that, the ratio changes to 5:1 in small and medium dogs, 6:1 in large dogs and 7:1 in giant dogs. This means that in 10 people years, an English Mastiff would be 80 years old and a poodle would only be 64.

This chart from The Dog Owner's Manual will help you calculate your dog's age:

The age at which your dog can be considered senior varies widely. In general, the larger the dog, the more quickly it declines. For instance, a Great Dane could be considered "senior" at age 5, while a smaller Pomeranian could still be spry at twice that age! Remember that a dog being chronologically old isn't necessarily a bad thing. In many cases, elderly dogs can enjoy many healthy, active and pain-free years.
