Dog Ages and Human Years

Your Dog's Age in Human Years

Though at one time we all believed that one year in your dog's life was the equivalent of seven in a human's life, that's now been proven untrue. Fortunately, veterinarians have developed a more realistic comparison of a dog's age to a human's age, as shown below. Keep in mind, however, that ‘old age' will occur at different ages for different dogs. In general, the onset of old age occurs for most dogs between the ages of five and ten, with the larger breed dogs toward the earlier end and the smaller breed dogs toward the latter end.
