Content: Large dogs who have reached 14 human years are 88 to 108 in dog years. The ratios for small dogs are more like 12:1, for medium-sized dogs, 10:1, and for large dogs, 9:1, but even that is only roughly accurate for the first two years of a dog’s life. As you may have guessed, comparing dog years to human years is inexact at best, but these measures for the first couple of years offer more reasonable estimates than the well-worn 7:1 ratio passed down over the ages in the fireside cackling of so-called old wives. Dog teeth provide a rough guide
The second frequently cited factor in determining a dog’s age in human years is the appearance of a dog’s teeth. Assuming that a dog is well looked after, cared for, and fed properly, the following are rules of thumb. 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.
