Content: Dental estimates for dog years are based on the number and condition of a dog’s teeth and converted with the same ratios as above to dog years. Once a dog’s teeth have come in, puppies have 28 teeth in total. Fully grown dogs have 42 teeth in total. By the time a dog is seven months of age, all of his permanent teeth will have come in. A dog with a full set of teeth that are still bright white will be in her first or second year, and thus, depending on size, anywhere from 10 to 18 in dog years. Teeth that appear to have some use and yellowing, found in a mouth that exhibits the familiar odor we refer to as “dog breath,” in a fully-grown dog, may indicate an age in human years of three to five. This would put that dog along a spectrum of 29 to 45 years of age in dog years, again, dependent on the dog’s size, breed and overall health. It is much more difficult to estimate an age for an older dog, who may be experiencing tooth decay or missing teeth. With a mouth in that sort of shape, it is generally safe to assume, however, that the dog will be in excess of 10 human years, or between 64 and 80 in dog years, if not older. The condition of a dog’s teeth is a far less precise method for determining dog years than when you have a general marker of human years, along with size, as a basis for your estimate.
