Yorkshire Terrier Lifespan: How Long Do Yorkies Live?

By Bianca Bello

Yorkshire Terriers — affectionately called Yorkies — are among the longest-lived dog breeds, with an average lifespan of 13 to 16 years. A landmark 2025 Royal Veterinary College study of UK Yorkies found their average lifespan at 13.56 years, well above the overall dog average of 12 years. Their small size, robust genetics, and relatively healthy breed profile contribute to remarkable longevity.

Yorkshire Terriers are toy breeds (typically 4-7 pounds), which is the single strongest predictor of long canine life. Small dogs accumulate cellular damage more slowly than large dogs, and Yorkies in particular have one of the most genetically diverse breed populations. The 2025 VetCompass UK study found that Yorkshire Terriers live an average of 13.56 years — about 1.5 years longer than the average dog. Female Yorkies live, on average, 1.5 years longer than males.

Common health considerations

Health to watch for in Yorkies.

Informational only — your vet remains the best source for clinical guidance.

  • Dental disease

    3+ years

    Most prevalent issue — Yorkies' tiny mouths crowd 42 adult teeth. The 2025 VetCompass study found dental disease as one of the most common diagnosed conditions. Daily brushing prevents this.

  • Tracheal collapse

    6+ years

    Narrowing of the cartilage rings in the windpipe, causing chronic coughing. Common in toy breeds. Use a harness, never a collar, on Yorkie leashes.

  • Hypoglycemia

    Under 5 months

    Low blood sugar — extremely dangerous in Yorkie puppies. Signs: lethargy, weakness, tremors. Requires immediate feeding (Karo syrup on gums) and vet visit.

  • Patellar luxation

    1-6 years

    Kneecap slips out of place. Common in small breeds. Often manageable without surgery; severe cases may need orthopedic correction.

  • Portosystemic (liver) shunt

    Under 1 year

    Birth defect where blood bypasses the liver instead of being filtered. Signs: stunted growth, neurological symptoms. Yorkies have elevated breed risk.

  • Cataracts

    8+ years

    Cloudy lens causing gradual vision loss. Genetic component. Surgery can restore vision; most dogs adapt well even without surgery.

  • Anal sac impaction

    Any age

    More common in Yorkies than most breeds. Signs: scooting, licking rear. Vet can express manually as needed.

Longevity tips

How to help your Yorkie live longer.

For Yorkies, three priorities dominate longevity: (1) Daily dental care — Yorkies are prone to severe periodontal disease due to their tiny mouths cramming 42 adult teeth. Daily brushing is non-negotiable. (2) Watch for hypoglycemia in puppies — small dogs can crash dangerously low on blood sugar; multiple small meals are essential. (3) Protect them from injury — at 4-7 pounds, a fall from a couch can be fatal. They're remarkably resilient little dogs when properly cared for.

Common questions

Common questions about Yorkies.

  • How long do Yorkshire Terriers live on average?

    A 2025 Royal Veterinary College study found Yorkshire Terriers live an average of 13.56 years — well above the dog average of 12 years. Most Yorkies live between 13 and 16 years, with many reaching 17 or 18 with excellent care. Female Yorkies live, on average, 1.5 years longer than males.

  • How old is a 5 year old Yorkie in human years?

    A 5-year-old Yorkshire Terrier is approximately 36 in human years. Yorkies are small breeds and age slowly — about 4 human years per dog year after age 2. The first year equals 15 human years, the second adds 9, and each year after adds 4.

  • At what age is a Yorkshire Terrier considered a senior?

    Yorkies are typically classified as senior at age 8 to 10. This is when annual bloodwork becomes standard, and you may notice subtle changes like longer naps, slight cloudiness in the eyes, or reduced enthusiasm for stairs. Many Yorkies remain remarkably active well into their teens.

  • Why do Yorkies live so long compared to other breeds?

    Body size is the single strongest predictor of canine lifespan, and Yorkies are tiny — typically 4 to 7 pounds. Small dogs accumulate cellular damage more slowly than large dogs and put less strain on their organs. The Yorkshire Terrier also has a relatively diverse gene pool, contributing to their longevity.

  • What is the most common health issue in Yorkshire Terriers?

    Dental disease is the most common health issue in Yorkies. Their small mouths crowd 42 adult teeth, creating ideal conditions for plaque buildup and gum disease. Daily brushing and annual professional cleanings are the single most impactful things you can do for your Yorkie's longevity.

  • How can I help my Yorkshire Terrier live longer?

    Three things matter most for Yorkies: brush their teeth daily (genuinely daily — not weekly), keep them at a lean weight (you should feel ribs without pressing), and protect them from injury. At 4-7 pounds, a fall from furniture can be devastating. Multiple small meals daily prevent hypoglycemia in puppies and seniors alike.
