A 1-year-old Yorkie is about 15 in human years, a 5-year-old about 36, and a 10-year-old about 56. Yorkies usually live 11–15 years (about 60–76 human years).
How old is my Yorkie in human years?
Yorkies were first bred in 19th-century Yorkshire to catch rats in mills. Like all dogs, Yorkies grow up fast: a 1-year-old Yorkie is about 15 in human years and a 2-year-old about 24. After that, the Yorkie follows the small-dog aging curve used by the AKC and AVMA, adding about 4 human years per year.
That means a 5-year-old Yorkie is about 36, a 10-year-old is about 56, and a 15-year-old is about 76 in human years. The old "multiply by 7" rule gets this wrong at almost every age — it says a 1-year-old Yorkie is only 7, when it's really a teenager.

Yorkie lifespan: how long do Yorkies live?
The typical Yorkie life expectancy is 11–15 years. In human terms, reaching 11 years is like reaching about 60, and 15 years is like reaching about 76 — so a long-lived Yorkie can be the equivalent of a person in their 70s.
Health concerns commonly discussed for Yorkies include dental disease, tracheal collapse and luxating kneecaps. Regular vet checkups, a healthy weight, daily exercise and dental care are the most reliable ways to help your dog reach the top of that range.
When is a Yorkie a senior?
The 2019 AAHA Canine Life Stage Guidelines define the senior stage as the last 25% of a dog's expected lifespan. For a Yorkie expected to live around 13 years, that begins at about 9.8 years (roughly 55 in human years). Watch for:
- A greying muzzle and cloudy eyes
- Sleeping more and slower walks
- Stiffness after rest, trouble with stairs or jumping
- Dental disease, weight changes or new lumps
Once your Yorkie is a senior, many vets recommend checkups about every six months.
How this Yorkie age calculator works
We map the Yorkie to the small size group (about 7 lb) and use the AKC/AVMA size-based chart: 15 human years at age 1, 24 at age 2, then the small-dog rate. Puppies under 1 year use veterinary life-stage milestones (about 10 human years at 6 months). The life stage follows AAHA guidelines, and we show the 2020 DNA-methylation formula (16 × ln(age) + 31) for comparison. For comparison, a large dog of the same age would be a different "human" age — see the dog age calculator by breed.
Frequently asked questions
How old is a 1 year old Yorkie in human years?
A 1-year-old Yorkie is about 15 human years old.
How old is a 5 year old Yorkie in human years?

What is the Yorkie lifespan in human years?
Yorkies typically live 11–15 years, which equals about 60–76 in human years.
When is a Yorkie considered a senior?
Around 9.8 years old — the start of the last 25% of its average 13-year lifespan, following AAHA guidelines.
Is 1 dog year equal to 7 human years for a Yorkie?
No. A 1-year-old Yorkie is about 15 in human years, not 7. The aging rate then slows to about 4 human years per year for a small dog.
How old is a Yorkipoo in human years?
A Yorkipoo (Yorkie × Toy/Miniature Poodle) is a small dog, so it follows the small-dog chart. Choose "Yorkipoo" in the calculator above. A 5-year-old Yorkipoo is about 36 in human years.
How long do teacup Yorkies live?
"Teacup" isn't an official size, and extremely tiny Yorkies are often more prone to health problems such as low blood sugar and fragile bones. A standard Yorkie typically lives 11–15 years; at 15 that's about 76 in human years.
