These charming little companions are known for being loyal, loving, and incredibly adaptable. But if you’re considering adding one to your family—or already have—you’re probably wondering: How long do Shih Tzus live?
What Is the Life Expectancy of a Shih Tzu?
The average lifespan of a Shih Tzu is between 10 and 16 years, with many living well into their teens when provided with proper care. This breed is known for its longevity, especially when compared to many larger dog breeds.
In fact, it’s not uncommon for healthy Shih Tzus to live 14 or 15 years, and some even reach 18 years old! Their small size, generally sturdy build, and affectionate nature all contribute to their reputation as long-living companions.
Factors That Influence a Shih Tzu’s Lifespan
Although genetics play a key role, there are several lifestyle and environmental factors that can impact how long a Shih Tzu lives.
The Shih Tzu is generally considered a healthy breed, known for its long lifespan, though it can face common health issues such as hip dysplasia and eye problems. Let’s take a closer look at what affects Shih Tzu lifespan:
1. Genetics
Reputable breeders carefully select parent dogs to minimize the risk of inherited conditions. Choosing a Shih Tzu from a breeder who conducts health screenings can increase your pup’s chances of living a longer, healthier life.
2. Diet and Nutrition
Feeding your dog a well-balanced, high-quality diet tailored to their age, size, and activity level supports their immune system, skin, coat, and organ function—all essential for longevity.
3. Exercise and Mental Stimulation
Shih Tzus may not require as much exercise as high-energy breeds, but they still need daily walks and playtime. Mental stimulation—such as puzzle toys and training—helps prevent boredom and promotes a well-rounded, happy life.
4. Veterinary Care
Routine vet visits, vaccinations, and dental cleanings are crucial for catching issues early and maintaining overall health. Preventive care is often more effective (and less costly) than reactive treatment.
5. Spaying or Neutering
Spayed and neutered dogs often live longer due to reduced risk of reproductive-related health problems and certain cancers.
Common Shih Tzu Health Issues
While Shih Tzus are relatively healthy overall, they can be prone to some breed-specific health concerns. Knowing what to look out for can help you catch problems early and keep your dog feeling their best.
1. Brachycephalic Syndrome
Shih Tzus are a brachycephalic (short-nosed) breed. This means their flat faces can make breathing more difficult, especially in hot or humid weather. Keeping your dog cool, avoiding strenuous activity during high heat, and maintaining a healthy weight can all help.
2. Dental Disease
Like many small breeds, Shih Tzus are prone to dental issues, including gum disease and tooth decay. Regular brushing and professional cleanings are important to keep their mouths healthy and free of infection.
3. Eye Problems
Those big, beautiful eyes are unfortunately prone to issues like corneal ulcers, dry eye (keratoconjunctivitis sicca), and infections. Regular eye cleaning and routine vet checks can help keep eye problems in check.
4. Hip Dysplasia and Joint Issues
Though more common in large breeds, Shih Tzus can experience joint issues as they age. A joint-supportive diet and low-impact exercise can help manage stiffness and support mobility.
5. Allergies and Skin Conditions
Shih Tzus may have sensitive skin or allergies, which can lead to itching or hot spots. Gentle grooming and hypoallergenic products can help maintain skin health.
The Shih Tzu’s coat is a long, luxurious double coat that requires regular grooming to prevent tangling and matting, which can lead to skin infections and other health issues. Regular grooming is essential to maintain their coat’s health and appearance.
How to Help Your Shih Tzu Live a Long, Healthy Life
Supporting a long Shih Tzu lifespan isn’t just about adding years to their life—it’s about adding quality to those years. Here are some evidence-based ways to help your pup thrive:
Maintain a Healthy Weight
Obesity can lead to heart issues, joint pain, and diabetes. Measure your dog’s food, limit high-calorie treats, and prioritize daily walks.
Prioritize Dental Care
Brush your dog’s teeth regularly using canine toothpaste, and vet cleanings to prevent painful infections.
Keep Up With Grooming
That luxurious coat requires regular maintenance. Brush your Shih Tzu daily to avoid mats and tangles, and schedule grooming every 4–6 weeks. Clean their ears, wipe their face, and keep their nails trimmed.
Provide Mental Enrichment
Keep your Shih Tzu sharp and satisfied with interactive toys, training sessions, and social interaction. A bored dog is more likely to develop stress-related behaviors.
Stay on Top of Vet Visits
Annual (or biannual for seniors) checkups help detect and manage age-related conditions. Discuss any behavior or physical changes with your vet—early detection is key.
What to Expect as Your Shih Tzu Ages
A Shih Tzu is considered a senior around age 9 or 10, though many remain active and playful for years after. As your dog enters their golden years, you may notice:
- Decreased energy levels
- Slight stiffness in the joints
- Graying of the muzzle or coat
- Changes in vision or hearing
- More frequent naps
During this stage, focus on senior-specific care, such as orthopedic bedding, and gentle walks. Keep a close eye on appetite, weight changes, or bathroom habits, and adjust their diet as needed.
Comparing Shih Tzu Lifespan to Other Dog Breeds
When it comes to lifespan, Shih Tzus stand out among dog breeds. According to the American Kennel Club (AKC), the average lifespan of a dog is around 10-13 years. However, Shih Tzus often surpass this average, living longer than many other breeds, including some larger dogs.
For instance, the Lhasa Apso, a breed similar to the Shih Tzu, typically lives around 12-15 years. Toy breeds like the Shih Tzu generally enjoy longer lifespans compared to larger breeds, with some Shih Tzus living up to 18 years or more. This extended lifespan makes Shih Tzus a wonderful choice for those seeking a long-term furry companion.
Final Thoughts
The Shih Tzu lifespan often stretches into the mid-teens, giving pet parents many years of joyful companionship. These little dogs may be small in size, but their hearts are full of personality—and with the right care, they can stay by your side for a long, healthy life.
Whether your Shih Tzu is a bouncy puppy or a wise old friend, every stage of their life deserves attention, affection, and health-focused habits. With love, routine care, and a proactive approach, your Shih Tzu can enjoy every year to the fullest.
