People often say that one human year is the equivalent of seven ‘dog years’, but in reality, the math isn’t that simple. Dogs mature more quickly than we do early on. So the first year of your fuzzy friend’s life is equal to about 15 human years.

Size and breed also play a role. Smaller dogs tend to live longer than larger ones, but they may mature more quickly in the first few years of life. A huge pup might age more slowly at first, but be nearing middle age at 5. Tiny and toy breeds don’t become “seniors” until around age 10. Medium-sized pooches are somewhere in the middle on both counts.

Determine how old your dog is

If you got the puppy from a breeder, you may know exactly how old your dog is, but if you adopted the dog whose age is unknown, her teeth should give you a rough idea. These guidelines will vary from dog to dog, and they also depend on the kind of dental care (if any) she had before you got her.

  • By 8 weeks: All baby teeth are in.
  • By 7 months: All permanent teeth are in and are white and clean.
  • By 1-2 years: Teeth are duller and the back teeth may have some yellowing.
  • By 3-5 years: All teeth may have tartar buildup and some tooth wear.
  • By 5-10 years: Teeth show more wear and signs of disease.
  • By 10-15 years: Teeth are worn, and heavy tartar buildup is likely. Some teeth may be missing.
