Shih Tzu Lifespan: How Long Do They Live?
Everything you need to know about the Shih Tzu's life expectancy, factors that affect longevity, and tips to help your dog live a longer, healthier life.
Shih Tzu Life Expectancy
The Shih Tzu has an average lifespan of 10 to 18 years, which is average for dogs of their size category. Shih Tzus typically live 10 to 18 years, with many reaching their mid-teens. Their longevity is a testament to generations of selective breeding for robust health..
Several factors influence an individual Shih Tzu's lifespan, including genetics, diet, exercise, veterinary care, and overall lifestyle. Dogs from health-tested parents who receive consistent preventive care tend to live the longest.

Shih Tzu Lifespan by Gender
| Male | 10–18 years |
| Female | 10.5–18.5 years |
Gender differences in Shih Tzu lifespan are generally modest. Both male and female Shih Tzus benefit equally from quality nutrition, regular exercise, and consistent veterinary care. Spaying and neutering timing can influence longevity, and your veterinarian can recommend the optimal age based on your dog's individual health profile and the latest research for small breeds.
Factors That Affect Shih Tzu Lifespan
The lifespan of your Shih Tzu (10–18 year average) is shaped by:
- Genetics: Start with a dog from parents tested for Brachycephalic Airway Syndrome
- Feeding: Portion-controlled nutrition maintaining 9–16 lbs
- Exercise: Low exercise needs suit them perfectly for apartment life. A few short walks daily and indoor play sessions keep them happy and healthy.
- Veterinary partnership: Regular checkups with screening for Brachycephalic Airway Syndrome and other breed conditions
- Weight control: Lean body condition (ribs palpable, visible waist) can extend life by up to 2 years
- Grooming: Regular care of their long double coat coat supports skin health and allows early detection of lumps or skin changes
Tips to Help Your Shih Tzu Live Longer
To help your Shih Tzu live their longest, healthiest life (10–18 year potential):
- Feed a high-quality diet and measure portions to maintain 9–16 lbs
- Provide 50+ minutes of daily exercise—Low exercise needs suit them perfectly for apartment life. A few short walks daily and indoor play sessions keep them happy and healthy.
- Keep up with all vaccinations and parasite prevention
- Schedule annual veterinary checkups (twice yearly after age 8)
- Screen proactively for Brachycephalic Airway Syndrome, the breed's primary health concern
- Maintain their long double coat coat with regular grooming to prevent skin issues
- Address health concerns promptly rather than waiting
Shih Tzu Life Stages and Aging
Understanding how the Shih Tzu ages helps owners provide stage-appropriate care that maximizes both quality and length of life. As a small-sized breed, the Shih Tzu progresses through life stages at a slower rate than larger breeds, often maintaining youthful energy and vitality well into what would be old age for bigger dogs.
Puppy stage (0–12 months): The foundation for a long, healthy life is laid during puppyhood. Proper nutrition formulated for small-breed growth, timely vaccinations, early socialization, and appropriate exercise all contribute to lifelong health. This is the ideal time to establish a veterinary relationship and baseline health records.
Adult stage (1–6 years): The Shih Tzu's prime years are characterized by stable energy, established temperament, and relatively low health risks when preventive care is maintained. Annual veterinary checkups, consistent exercise, dental care, and weight management at 9–16 lbs are the pillars of care during this stage.
Senior stage (6+ years): As the Shih Tzu enters the senior phase, increase veterinary visits to twice yearly. Watch for signs of age-related conditions including joint stiffness, vision or hearing changes, cognitive decline, and changes in appetite or energy. Adapt exercise to lower-impact activities, consider joint supplements, and adjust diet to senior-appropriate formulations.
Common Causes of Death in Shih Tzus
Understanding the leading causes of death in the Shih Tzu helps owners focus preventive efforts where they matter most. While individual outcomes vary, research and breed health surveys identify consistent patterns.
The breed's known health predispositions, including Brachycephalic Airway Syndrome, Keratoconjunctivitis Sicca, Patellar Luxation, contribute to mortality rates. Proactive screening for these conditions, particularly in the breed's later years, can detect problems early when treatment is most effective.
Cancer remains one of the leading causes of death across all dog breeds. Regular veterinary examinations that include palpation of lymph nodes and discussion of any lumps or behavioral changes help catch malignancies early. Maintaining a healthy weight throughout life reduces cancer risk, as does limiting exposure to environmental toxins.
Accidents and trauma are preventable causes of premature death. Keep your Shih Tzu on a leash or in a securely fenced area, ensure identification through microchipping and collar tags, and pet-proof your home and yard to eliminate hazards.
