How Long Do Shih Tzu Live – Lifespan And Longevity

how long do shih tzu live

Shih Tzu live for 13 years on average.

Factors which affect how long Shih Tzu live include their genes and the lifetime care they receive.

Shih Tzu lifespan compares well to the average lifespan of all purebred dogs taken together, but some hereditary health conditions mean that a long life doesn’t always equal good quality of life.

How Long Do Shih Tzu Live?

The average Shih Tzu lifespan is a little over 13 years. According to a UK study, the average purebred lives around 11 years.

Shih Tzu live longer than your average dog. But when we’re talking about health, things get a little more complicated.

Small dogs live longer than larger ones on average, which gives the Shih Tzu an advantage in that department.

But a Shih Tzu’s face shape gives it a disadvantage when it comes to living a healthy life.

Health Problems That Impact Shih Tzu Life Expectancy

Shih Tzu face many health concerns that can impact their life expectancy. The question, “How long do Shih Tzu live?” doesn’t always have a straightforward answer.

There are a number of things that impact a dog’s lifespan. Two of the big ones are size and shape.

First, we’ll look at a dog’s size. Giant breeds tend to live shorter lives than tiny breeds. For a Shih Tzu, there’s nothing to worry about here.

Secondly, we’ll look at shape. The shape of a dog’s body can cause health problems known as conformational defects.

In simple terms, one or more of the breed’s features are too large or too small, and this causes complications.

Some of these can be very serious, as in the case of the Shih Tzu. We’ll look into this below, along with some other health concerns Shih Tzu face.

How Long Do Shih Tzu Live With Conformational Defects

A Shih Tzu’s short muzzle often causes trouble breathing and issues with overheating. Their small size makes the problem even worse.

Shih Tzu may not be able to tolerate a lot of exercise, especially on hot days. Owners have to be careful to watch for signs of overheating and not keep them out in the heat too long.

They can also face respiratory issues because of this.

Another conformational defect Shih Tzu face is patellar luxation, which is common in small breeds. This is when a dog’s kneecap is dislocated.

They can also face dental problems because their mouths are so tiny.

Hip Dysplasia

Hip dysplasia happens when the hip socket doesn’t develop properly. This can cause pain and arthritis.

A veterinarian can diagnose and come up with a treatment plan for a Shih Tzu with hip dysplasia.


Hypothyroidism occurs when a Shih Tzu’s thyroid is not producing enough hormones. This can affect a dog’s metabolism and organ function.

A veterinarian can diagnose and treat hypothyroidism.

Eye Diseases

The eyes of a Shih Tzu are prone to injuries. They can also face a number of eye diseases.

Dry eye is when a dog is not producing enough tears. If not treated, a Shih Tzu with dry eye might develop ulcers or become blind. Shih Tzu with dry eye will have a lot of discharge around their eyes. A veterinarian can treat this problem with eye drops.

Distichiasis is another common eye problem in Shih Tzus. This means they have an extra set of eyelashes. Sometimes this doesn’t impact the dog at all, while other times it can be very irritating or even harmful.

A veterinarian can help with proper treatment of this condition, depending on the severity.

Corneal ulcers are also common in Shih Tzu, as their eyes are large and protrude from their face. An affected Shih Tzu will have light sensitivity and may squint a lot, or have red eyes.

This can cause blindness. However, if caught early it can be managed by a veterinarian.

Lastly, Shih Tzu may develop cataracts. This means the lens of their eye becomes cloudy due to too much protein in the lens. This causes the pupil to look clouded or white.

As cataracts continue to develop, the dog will lose vision in that eye. If caught early, a veterinarian can help diagnose and treat cataracts before it gets that serious.

Kidney Disease

Juvenile renal dysplasia is a genetic disease. This is when kidneys don’t develop right. Many times this will impact many puppies within a single litter.

Most dogs with this disease, unfortunately, die from it.

Liver Disease

Shih Tzu can develop a disease called liver shunt. This compromises the flow of blood to and from the liver.

Shih Tzu can be born with this disease.

Dogs with liver shunt don’t grow normally and are smaller and weaker than other Shih Tzu their same age.

A veterinarian can diagnose liver shunt and provide a treatment plan.

Ear Infections

Shih Tzu ears are prone to infection. To prevent this, they should be cleaned regularly.

Dogs should be taken to the veterinarian when itching or redness occurs.


Shih Tzu can have many types of allergies. If you think your dog has allergies, see a veterinarian to find out what they’re allergic to, and how to treat it.

If you’re adopting from a breeder, the very first thing you can do is to know your dog’s medical history. A good breeder will share this with you. Do not buy a dog from someone who won’t share the parents’ and puppy’s vet records.

Sometimes a breeder is irresponsible and doesn’t have the parents tested for health problems, or breeds them despite knowing they will pass down genetic conditions.

The only time you shouldn’t know your dog’s history is when you’re adopting them as a rescue. In this case, it’s impossible, and we just do the best we can with the information we have.

If you own a rescue dog, you can consider having it tested for some common health problems.
