How long do shih tzu live? On average, shih tzus live between 10 and 16 years, with many reaching 13 to 15 years when given proper care. Their small size generally helps them live longer than larger breeds, but their short noses make them sensitive to heat and strenuous exercise. Paying attention to their comfort, diet, and daily routine can help them stay healthy and happy throughout their lives.
Understanding their different life stages helps owners provide the right care at the right time. From playful puppies to senior dogs, regular vet checkups, balanced nutrition, and gentle exercise keep your shih tzu feeling active and comfortable for many years.
How Long Do Shih Tzu Live?
Shih tzu dogs usually live for 10 to 16 years, with the average lifespan around 13 to 15 years. Some reach their late teens, especially when weight is kept lean and breathing is protected in hot weather. They enter their senior stage around 9 to 10 years, a time to focus on routine checkups and gentler exercise.
Their small size helps longevity, but their short muzzle can make heat and strenuous activity challenging. Providing thoughtful pacing, shaded areas, and cool resting spots supports their heart and airway as they age. Mixed shih tzus generally fall within the same range.
Shih tzu females usually live about one year longer than males, possibly due to hormonal protection. Spayed females also avoid risks from heat cycles and pregnancies, which can contribute to a healthier life.

Understanding the Life Stages of a Shih Tzu
The puppy stage lasts from birth to about 10 months. Growth is rapid, basic manners form, and initial vet care sets a foundation for health. Gentle handling, routines, and early socialization build confidence.
From 10 to 24 months, your shih tzu is a young adult. Height is mostly set, muscles and coordination develop, and training habits formed now tend to stick, so short, positive sessions work best.
The prime adult stage spans 2 to 8 years. Energy is steady, joints are healthy, and daily walks maintain a lean body. Dental care supports long-term health.
Around 9 to 12 years, your shih tzu becomes a senior. Exercise should be gentler, stairs and jumps may be harder, and joint support helps. For 13 years and beyond, pace slows, eyesight or hearing may decline, and extra rest is recommended. Some reach late teens, with rare cases living up to 23 years.
Factors That Affect a Shih Tzu’s Lifespan
A shih tzu’s lifespan depends on good genetics, maintaining a healthy weight, and proper daily care. Breathing, dental health, and eye protection all play an important role in their long-term well-being. Regular vet visits help catch issues early and keep your dog healthy for many years.
Genetics and Early Checks
Longevity often runs in families. When looking for a shih tzu for sale, ask the breeder about the lifespan of the puppy’s parents and grandparents. Check whether they were screened for healthy eyes, knees, and breathing. Always request proof of health tests and clear care instructions to give your puppy the best start. If your breeder won’t give this information, it’s best to steer clear of them; you can find reliable breeders on curated shih tzu sale listings to be safe.
Weight and Food
Extra weight can strain the heart, lungs, and joints. Feed measured meals and use treats in moderation. Your shih tzu should have a visible waist, and you should be able to feel its ribs easily without pressing too hard.
Breathing and Heat
Short noses can lead to noisy breathing and make it harder for your shih tzu to cool down. Take walks during cooler parts of the day, keep water available, and use harnesses that don’t put pressure on the neck.
Teeth and Gums
Dental problems can cause pain and infections that may shorten your shih tzu’s life. Brush their teeth daily, provide dental chews designed for small dogs, and schedule professional cleanings regularly.
Eyes and Injuries
Shih tzus have large eyes that can be easily scratched or become dry. Their small bodies are also at risk of injury from jumping off furniture. Keep the hair around their eyes trimmed, use ramps or steps for couches and beds, and supervise play with larger dogs.
Vet Care and Prevention
Regular vet visits help catch health problems early. Stay up to date with vaccines, parasite control, and senior blood tests, and provide gentle recovery after any health issues to support long-term well-being.
Common Health and Aging Concerns in Shih Tzus
Late-life issues in shih tzus are often caused by cancer, heart valve problems, or breathing and dental issues. Some dogs may develop kidney or liver problems, and repeated infections can leave senior dogs weak.
Signs that the end of life may be approaching include eating less, trouble breathing, confusion, excessive sleep, and a loss of interest in usual activities. Veterinary support can provide comfort care through pain relief, gentle fluids, soft food, and a calm, cool environment.
Helping Your Shih Tzu Live a Long, Healthy Life
Focus on healthy weight, regular vet visits, gentle exercise, and proper grooming to keep your shih tzu happy and healthy.
With consistent care and attention, your shih tzu can enjoy a comfortable, active life well into their senior years.
