how long do shih tzu live

Shih Tzus typically live around 10–16 years , and many reach their early to mid-teens with good care, with rare cases reported up to about 18–20+ years and even 23.

How Long Do Shih Tzu Live?

Quick Scoop

• Average life expectancy: 10–16 years.

• Many healthy Shih Tzus comfortably reach 13–15 years.

• Some exceptional dogs have been recorded at 18–20+ years , with the oldest documented around 23 years.

• As a toy breed, they generally live longer than many larger dogs.

Typical Lifespan Range

Most sources agree that the standard Shih Tzu lifespan falls between 10 and 16 years. Within that range, the “average” often cited is around 13 years , with quite a few living beyond that when well cared for.

Some guides and health articles note that, in particularly healthy lines with attentive owners, Shih Tzus can push into the upper teens , and there are rare reports of individuals reaching 18–20+ years and a record around 23 years old.

Why Their Lifespan Is Relatively Long

• Small size advantage : Toy and small breeds like Shih Tzus generally live longer than large breeds, which age faster.

• Sturdy little companions : They are usually robust for their size, which supports a solid lifespan when health issues are managed.

However, they do have breed-specific risks—such as dental problems, eye issues, and brachycephalic (short-nose) breathing concerns—so managing those is key to keeping them in that upper lifespan range.

Factors That Affect How Long a Shih Tzu Lives

Health and genetics

• Inherited issues (respiratory, eye, joint, and some cardiac conditions) can shorten life if not monitored and treated.

• Some sources note that females may live about 1.5 years longer than males on average , though this is a general trend, not a guarantee for an individual dog.

Lifestyle and daily care

• Diet : A balanced, high-quality diet and keeping them at a healthy weight reduces obesity-related complications and strain on the heart, joints, and breathing.

• Exercise : Regular, moderate activity helps maintain weight, muscle tone, and mental health, which can positively influence lifespan.

• Vet care : Routine checkups, vaccines, dental cleanings, and early treatment of issues are all repeatedly highlighted as longevity boosters.

• Grooming and hygiene : Consistent grooming (coat, skin, ears, eyes, teeth) helps prevent infections and chronic discomfort that can affect long-term health.

• Environment & mental health: Safe housing that minimizes accidents and attentive handling of stress or separation anxiety can improve both quality and potentially length of life.

Forum & “Real Owner” Perspective

On Shih Tzu–focused communities and forums, owners often report dogs living well into their teens and swap tips on “secrets” to a long Shih Tzu life—consistent routines, good food, dental care, and prompt vet visits come up again and again. While individual anecdotes vary, the pattern matches what health articles say: there’s no magic trick, just steady, long-term care.

You’ll also see people reminding each other that every dog is different, even within the same breed and household, so expectations should be a range rather than a fixed number.

Simple Takeaway for Owners

If you’re planning life with a Shih Tzu, it’s realistic to expect a commitment of about 12–15 years , with a fair chance of reaching the mid-teens if you stay on top of health, weight, grooming, and vet care. A small number may live close to 20 years or a bit beyond, but that should be seen as a happy exception rather than the rule.
