Do Dogs Get 7 Years Older Every Human Year?

No, in the first few years of a dog's life it ages much faster than the rest of its life. Also it depends on the bread of dog. Small dogs live longer than large dogs, so it is hard to tell. Also every dog lives for a certain amount of time, so you could only accurately measure dog years after the dog is deceased. So all in all you can't measure a dog's age by using the old dog years trick.  -John Baskin
