Most people have heard one human year equals seven years for a dog. Is this factual or merely an old wives tale? Today we are going to look at the true age of your dog and how you can discover this information. Most vets will look at a dog’s teeth and eyes as a way to estimate the true age of your dog but are there better methods than these?
One thing that I find very interesting is if we go by the traditional one year equals seven years why is it that a dog one year old in human years is in our eyes actually seven years old, yet this dog can breed and have a litter of healthy puppies? On the same vein of thought a ten year old dog who we think is actually seventy years old can also still breed and have puppies. How many people who are seven or seventy years old can claim the same physical abilities? None, so this shoots down the old one to seven ratio when you’re comparing dog years to human years. This is not an accurate way for estimating the true age of your dog, so is there a better way? Yes, actually there is.
A French veterinarian began to study this dog to human age theory in the 1950’s, and he came up with what appears to be a very accurate formula for precise aging of dogs. He took a new approach by factoring in the age when a dog reaches puberty and when the dog becomes a fully mature animal. By comparing this information with humans he came up with 15 years old for the first year of a dog’s life, and by the end of the dogs second year he or she would be 24 years old when compared to human age. Now the aging slows down to equal four years added to the dog’s life for each human year.
Base on this new formula for aging a dog, how old would your dog be? If you have a 5 year old pooch he is 35 years old according to the old seven to one ratio. Using the new formula he is 36. Not a big difference, but when the dog has reached ten human years of age he is now 70 years old using the 7 to one. Using the new formula he is actually only 56 years old.
I believe this French Vet was on to a more accurate formula for aging dogs, so what is the true age of your dog?
