Basic Shih Tzu Health Issues

The Shih Tzu can reach the lifespan of 11-16 years. Just like with any small dog breed, the Shih Tzu has its share of health conditions that owners should be aware of. As an owner, it is your responsibility to care and provide the needs of your companion.

It is important to note that Shih Tzus have unique features – short-legged with a long back and brachycephalic (flat face). The flat face feature is due to a smaller upper jaw where all the tissues within are bigger than what the jaw can accommodate. Both these features are linked to various health issues.

Common Shih Tzu Health Issues

Shih Tzus are considered to generally be a healthy breed but…like most dog breeds…they are susceptible to certain diseases and conditions.

Eye Problems

Shih Tzus are susceptible to eye problems due to the shape of the head and face. As a brachycephalic breed, they have a flat face and large, protruding eyes which are prone to exposure to the environment.

Remember that injuries can occur by scratching the eye corners which can lead to puncturing their eyes. You should protect your dog from any sharp objects around the house and keep their hair away from the eyes to avoid irritation.

Even though some eye conditions have a hereditary link, most are brought aboutShih Tzu Health by trauma and irritation due to the position and shape of the eyes. Generally, infections are likely due to the lack of protection against foreign objects.

Sadly, the eye conditions that are likely to affect the breed include the following:

  • Corneal Ulcers: A common form of eye injury that can be due to eye trauma, foreign object in the eye, lack of tearing, eye infection and abnormal eye structure.
  • One or both eyelids turn inward towards the eyeball: This causes the eyelashes to rub continuously against the eyeball, leading to eye irritation.
  • There is an overflow of tears that can stain the fur beneath the eyes.
  • Progressive Retinal Atrophy: A degenerative disease affecting the retinal visual cells that eventually leads to blindness.
  • Keratopathy Syndrome: A corneal disease characterized by a brown pigmentation across the cornea. It is often accompanied by scar tissue formation and blood vessel infiltration that cause pain or discomfort. In severe cases, it can lead to blindness.
  • The eyeball bulges out of its orbit where the blood flow is disrupted. This leads to a lack of oxygen which can lead to blindness.
  • Opaque cloudiness that affects the eye lens. It affects the vision of your Shih Tzu which ranges from minor impairment to blindness.
  • Ingrown eyelashes can scrape and irritate the eye or even scar it.
  • Harderian Gland Prolapse: The glands in the eyelids become swollen. Once the gland moves with a loose connection, it causes excessive drainage, swelling, bloody ulcerations, and even conjunctivitis.
  • Retinal Dysplasia: This is a hereditary condition involving an irregularity in the retina. It results to folded tissue layers in the retina instead of a normal flat tissue that can lead to minor visual impairment or even blindness.
  • Keratoconjunctivitis Sicca: A condition that results to dryness of the cornea and the conjunctiva.

Due to the variety of eye conditions, a specific sign might be an indication of a specific issue. Once you notice any of these signs, it is best to see a veterinarian right away for proper assessment.

Some of the usual signs of an eye problem include:

  • Eye swelling and redness
  • Increased tear production
  • Eye pain or discomfort
  • Pupil discoloration
  • Loss of peripheral vision
  • Night blindness
  • Protrusion from the side of the eye

Which treatment is used will be based on the specific eye condition. In minor cases, the application of eye drops or removal of the eyelashes is enough but severe cases might necessitate surgical intervention.

Majority of the eye conditions are brought about by eye irritation. In such cases, the treatment aims at the removal of the foreign object or hair. Luckily, the health conditions linked with the eyes are rarely life-threatening.


Shih Tzu HealthShih Tzus are also prone to various types of allergies – food allergies, contact allergies, and inhalant allergies.

It is important to note that this breed is prone to allergies along with its flattened face which contributes to breathing issues.

In some instances, an allergy can aggravate the breathing issues, but allergies are more likely to manifest as skin issues.

  • Contact Allergies: A reaction is brought about by a sensitivity to any topical substances such as shampoos, flea powders, bedding or other chemicals.
  • Inhalant Allergies: A reaction is triggered by exposure to airborne allergens such as dust, pollen or mildew.
  • Allergy to Flea Bites: Some dogs might be highly sensitive to the saliva in flea bites. If a Shih Tzu is allergic to flea bites, a single bite can trigger a reaction. The indications of this allergy include chewing, scratching and excessive licking of the site along with hair loss.

Depending on the type of allergy your Shih Tzu has the treatment might involve dietary limitations, environmental adjustments, and medications.

Brachycephalic Airway Obstruction Syndrome (BAOS)

This condition not only affects Shih Tzus but all dog breeds that have similar head structure. Due to the shorter form of the nose and the jaw the soft tissues of the mouth and nose are squeezed into a smaller space that can trigger breathing issues.

Brachycephalic airway obstruction syndrome generally refers to at least one of four specific conditions:

  • Elongated soft palate
  • Stenotic Nares: The nostrils are very narrow which has a significant impact on the respiratory system.

In most cases, the veterinarian will provide medications such as muscle relaxants and anti-inflammatory drugs along with adequate rest.

If rest and drugs are not effective surgical intervention is required.

Juvenile Renal Dysplasia

This is a hereditary condition where the kidneys do not develop normally which is most often seen among young dogs.
