We know the old rule of thumb, one year for a human is 7 dog years. Well, not so fast. How many 100 year old humans can run laps around you? Here is a quick reference guide to calculate what stage of life your dog may be in.
The chart below, use these general ranges for dog size: Small dog = 20 pounds or less Medium dog = 21-50 pounds Large dog= More than 50 pounds
|Dog's Age||Age in Human Years|
|Small breed||Medium breed||Large breed|
After 14 years of age, who knows? Its probably safe to say that if you have a small to medium breed dog, 15-16 years is like 90, and 17 or more years is like a 100. For a large breed, 15 years is like 90, and 16 + is like a 100. There is no exact way, but hopefully this correlates a little closer to human life spans, and provides you with a little more knowledge when looking at your dogs activity and health level.
