How Long Do Shih Tzus Live?

By Homestead Acres team · October 25, 2026

Bringing home a puppy means committing to many years together, and Shih Tzus are one of the longer-lived breeds. Understanding what affects lifespan helps you give your dog the best chance at a long, comfortable life.

The typical lifespan

Many Shih Tzus live between 10 and 16 years, and some go beyond that. Small dogs generally outlive large ones, and the Shih Tzu is a good example. Individual dogs vary based on genetics, weight, diet, dental health and the quality of veterinary care they receive. Plan for a friend who will be with your family through school years, moves and many other changes.

Life stages to expect

Your Shih Tzu will be a puppy for roughly the first year, an adult from about one to seven or eight years, and a senior after that. Each stage has its own needs. Puppies need vaccinations, socialization and training. Adults need steady exercise, grooming and a lean weight. Seniors need more frequent vet checks, joint support and gentler routines.

Keep a healthy weight

Extra pounds are one of the biggest threats to a small dog's longevity. Obesity stresses joints and the heart and makes breathing harder in a short-muzzled breed. Measure meals, use treats sparingly and keep your dog active every day. Ask your vet to check body condition at every visit.

Protect the teeth

Dental disease is common in small breeds and can affect the heart, kidneys and overall health. Brush your dog's teeth daily if possible, offer vet-approved dental chews and schedule professional cleanings when your vet recommends them. It is one of the highest-value habits you can build.

Take care of eyes, ears and skin

Shih Tzus' large eyes, drop ears and dense coat need regular attention. Wipe the eyes daily, check ears weekly and brush every day so skin stays healthy. Catching small problems early prevents bigger ones.

Mind the heat

The breed's short muzzle makes it harder to cool down. Keep your dog out of hot cars, avoid hard exercise in warm weather and provide shade and water. Use a harness instead of a collar so there's no pressure on the neck and airway.

Regular vet visits

Plan on at least a yearly checkup, and twice a year once your dog is a senior. Keep up with vaccines, parasite prevention and bloodwork as your vet recommends. Pet insurance or a savings fund for vet care gives you the freedom to say yes to treatment when it counts.

Mental and emotional health

Shih Tzus are companion dogs, and they do best when included in family life. Play, training games, short walks and plenty of cuddles keep your dog's mind and mood healthy. Avoid leaving a Shih Tzu alone for long hours.

Starting right

A good start matters. Choose a puppy that is alert, well socialized and has had proper early care, and book a vet checkup right away. If you have questions about the puppies we have, call or text us.

Signs of aging to watch for

Gray around the muzzle, slower movement, more sleeping, stiffness after rest, cloudy eyes and hearing changes are normal as dogs age. Weight loss, a dramatic appetite change, a persistent cough, bad breath, excessive thirst or accidents in the house deserve a vet visit. Early attention makes a big difference to comfort and quality of life.

Making life comfortable for a senior

Provide a warm, supportive bed, ramps or steps for furniture, non-slip rugs on hard floors and shorter, gentler walks. Keep grooming gentle and regular. Ask your vet about joint support, dental care and diet changes. Senior dogs still love to play and cuddle, and the extra comfort lets them enjoy it.

Planning for the long run

Because Shih Tzus can live well into their teens, set aside time and money for the whole journey. A puppy is a long relationship, and the families who plan for it are the ones who enjoy every year.

Small habits that add up

Daily brushing, dental care, healthy meals, regular walks, time with you and vet visits seem simple, but together they make a big difference. Keep a calendar for shots, parasite prevention and grooming. Take photos regularly and watch for changes in weight, appetite and energy. The owners who notice small changes early are the ones who give their dogs the longest, healthiest lives.

Your dog's life is in your hands in countless small ways, and each of them is a chance to show love.
