Shih Tzu Health Issues in Sydney

Shih Tzus are affectionate, long-lived little dogs, but the flat face and small frame bring a health picture worth understanding before you adopt. Plan for brachycephalic breathing and real heat intolerance, the vulnerable prominent eyes, crowded-mouth dental disease, slipping kneecaps, back problems, ear and skin issues, and a breed-associated kidney condition. Lifespan is commonly 12 to 15 years, and most of the risk is managed with a lean weight, good dental and eye care, a harness, and sensible heat management. Here is the plain-language picture, what to watch for, and when to see a vet.

The short answer

The Shih Tzu is a long-lived, affectionate breed with predictable weak spots that come from its flat face and small frame. The flat face means brachycephalic breathing in some dogs and real heat intolerance, so summer management matters in Sydney. The large, prominent eyes are prone to corneal ulcers, dry eye and, in an emergency, being knocked out of the socket (proptosis). The crowded mouth means dental disease is very common. Beyond those, plan for luxating patella, back and disc problems, ear and skin issues, and a breed-associated kidney condition, renal dysplasia. Use a harness not a collar, keep the dog lean, brush the teeth, protect the eyes, manage the heat and stay on year-round tick prevention. Lifespan is commonly 12 to 15 years. This is general information, not veterinary advice; for your dog, always talk to your vet.

A note on this guide: this is general educational information for prospective and current Shih Tzu owners, not veterinary advice. Every dog is an individual. For diagnosis, treatment or advice about your specific dog, always consult a registered veterinarian, and never medicate a dog based on an article.

The flat face: breathing and heat

The most important thing to understand about Shih Tzu health is the flat face, because it drives both the breathing risk and the heat risk. The Shih Tzu is a brachycephalic breed, which means a shortened muzzle and a compressed airway. In some dogs this causes brachycephalic obstructive airway syndrome (BOAS), where narrowed nostrils, an overlong soft palate and a narrow windpipe make breathing harder work than it should be.

Not every Shih Tzu is badly affected, and many breathe reasonably well, but the signs to know are snoring and snorting, noisy or laboured breathing, poor exercise tolerance, and struggling in the heat. If your dog breathes noisily at rest, tires quickly, or makes a harsh honking or gasping sound, have your vet assess the airway. Keeping the dog lean helps a lot, because extra weight makes any airway problem worse, and the Australian Veterinary Association has campaigned on the welfare issues of flat-faced breeds. For significantly affected dogs, surgery can improve the airway, and your vet is the person to advise.

Because panting is how a dog sheds heat, and a flat face pants less efficiently, the Shih Tzu feels the Sydney summer more than a long-nosed dog. That makes heat management a genuine health issue, not a comfort one, and we cover it fully further down.

The eyes: the breed's most vulnerable feature

Those large, round eyes are part of the Shih Tzu's charm and its biggest vulnerability. Because the eyes sit prominently in shallow sockets, they are exposed to knocks, scratches and drying, so a few problems are common:

The most serious risk is proptosis, where a blow to the head or face, or even rough handling, forces the eyeball forward out of its socket. It looks alarming and it is a genuine emergency. Keep the eye moist with saline or a clean damp cloth, do not try to push it back yourself, and get to a vet immediately, because fast treatment gives the best chance of saving the eye. Sydney has 24-hour specialty and emergency hospitals, including SASH, so know your nearest before you ever need it.

Day to day, watch for squinting, pawing at the eye, redness, cloudiness or discharge, and treat any of these as a reason to see a vet promptly rather than wait, because eye problems can worsen fast. The single best prevention is keeping the hair trimmed away from the eyes, which is where the grooming and the health of the breed meet.

Dental disease: the crowded toy-breed mouth

Dental disease is one of the most common problems in the breed, and it comes down to the mouth. A Shih Tzu has a normal number of teeth crammed into a small, shortened jaw, so the teeth crowd and overlap, trapping food and plaque, which builds into tartar, gum disease and painful infections if nothing is done. Bad teeth are not only a mouth problem: dental disease causes ongoing pain and can affect general health.

The prevention is the same as for any small dog but matters more here. Daily tooth brushing with a dog toothpaste is the gold standard, backed up by vet-recommended dental chews and regular vet dental checks, with a professional clean under anaesthetic when your vet advises. Watch for bad breath, reluctance to eat hard food, pawing at the mouth, drooling or bleeding gums. The RSPCA Knowledgebase has sound general guidance on dental care. Start a routine early with a rescue dog and keep it up; it is one of the highest-value things you can do for a Shih Tzu.

Knees, back and joints

Luxating patella. A slipping kneecap is common in small breeds. It shows as an intermittent skip or hop in a back leg, or the dog holding a leg up for a few steps and then carrying on as normal. Mild cases are managed with weight control and activity management, while more severe ones may need surgery, and your vet grades the knee and advises.

Back and disc problems. The Shih Tzu has a slightly longer-bodied build and can develop intervertebral disc disease (IVDD), where a spinal disc bulges or ruptures and presses on the spinal cord. Signs range from a reluctance to jump, a hunched back or yelping when picked up, through to weakness or dragging of the back legs. Sudden back-leg weakness or paralysis is an emergency and needs a vet straight away. You lower the risk by keeping the dog lean, discouraging jumping on and off high furniture, using ramps or steps, and supporting the whole body when you lift. Databases such as the Orthopedic Foundation for Animals track patella scores in screened breeding dogs, though you rarely know a rescue dog's breeding history.

Hip problems can also occur in the breed, so any persistent limping, stiffness after rest, or reluctance to move as usual is worth a vet check. Across all of these, a lean body condition is the single most protective thing you control.

Ears, skin folds and kidneys

Ears. Shih Tzus have hairy, floppy ears that trap warmth, moisture and hair inside the canal, which invites ear infections. Signs are head shaking, scratching, a smell, redness or discharge. Keep the ears clean and dry, check them regularly, use only a vet-recommended cleaner rather than cotton buds pushed into the canal, and see your vet at the first sign of trouble, because a low-grade infection left alone can become chronic.

Skin and folds. The breed can develop allergies (itchy, inflamed skin, paw licking and recurrent infections), and the facial skin folds and the fold under the tail can trap moisture and become sore or infected if not kept clean and dry. Wipe and dry the folds regularly, keep the coat clean and mat-free, and see your vet for persistent itching or any sore, smelly skin. Good grooming and good skin health go hand in hand.

Kidneys. Renal dysplasia, where the kidneys do not develop normally, is a recognised breed-associated condition in the Shih Tzu and can reduce kidney function, sometimes in a young dog. We are deliberately not attaching a frequency figure, because reliable breed-specific numbers are not something we can verify, but it is worth knowing about. The signs of kidney trouble are increased drinking and urination, poor appetite, weight loss, vomiting and lethargy. If you notice these, especially in a younger dog, see your vet, because a blood and urine test can assess kidney function and early management makes a difference.

Why a Shih Tzu should wear a harness

A well-fitted harness is the sensible default for a Shih Tzu. A collar concentrates pressure on the throat and the front of the neck when the dog pulls, and in a small brachycephalic breed that already has a compromised airway, adding throat pressure is the last thing you want. A harness spreads the pressure across the chest and keeps it off the neck and windpipe, which makes walks more comfortable and protects the airway.

Use the collar for the council registration tag and identification, and clip the lead to a properly fitted harness for walking. It is a simple, cheap change that helps a breed that already works a little harder to breathe. If your dog coughs, gags or breathes noisily on the lead, mention it to your vet.

Heat, ticks and the Sydney climate

Heat is the number one seasonal risk for a Shih Tzu, because the flat face makes cooling by panting far less efficient. In a Sydney summer that means walking only in the cool of the early morning or evening, keeping the dog inside with a fan or aircon on hot, humid days, always providing shade and water, and never leaving the dog in a parked car, which can turn lethal within minutes. A short summer clip helps the dog stay cooler.

Learn the signs of heat stress: heavy, frantic panting that does not settle, drooling, bright red or bluish gums, weakness, distress and collapse. Treat overheating as a true emergency, cool the dog with tepid (not icy) water and airflow, and get to a vet straight away.

The paralysis tick is the other Sydney essential. It lives along the NSW coast and bushland, including the Sydney region, and its neurotoxin causes an ascending paralysis that is fatal without treatment. Keep your Shih Tzu on a vet-recommended monthly tick-prevention product without gaps, and physically check the coat down to the skin after any bush or coastal outing. A tick is easy to miss under a long coat, which is one more reason to keep the coat manageable. If you find a tick, or your dog develops wobbly back legs, a changed bark or trouble swallowing, see a vet immediately.

Budgeting and insurance

A Shih Tzu is a small dog with small-dog food and registration costs, but the breed carries a real chance of specific vet bills: eye surgery or ulcer treatment, dental work under anaesthetic, airway surgery, and management of back, kidney or skin problems. Each of those can run into three or four figures at a Sydney clinic or referral hospital, so the cheap-to-feed small dog is not always cheap to keep.

That is why pet insurance taken out while the dog is young and healthy is a sensible decision with this breed, before anything becomes a pre-existing exclusion. Compare a few Australian providers on chronic and hereditary cover, the annual limit and the excess. It is not a substitute for an emergency fund, but for a brachycephalic breed with predictable eye, dental and airway needs it often pays for itself. We cover the full cost of adopting and keeping the breed in our Shih Tzu adoption guide, and the coat routine that protects the eyes and skin in our grooming and coat care guide.

Frequently Asked Questions

What health problems are Shih Tzus prone to?

Shih Tzus are affectionate, long-lived little dogs, but the breed carries a set of predictable risks that come from its flat face and small frame. The big one is brachycephalic (flat-faced) anatomy, which means noisy or laboured breathing in some dogs and real heat intolerance. Their large, prominent eyes are vulnerable to corneal ulcers, dry eye and, in an emergency, the eye being knocked out of its socket. The crowded toy-breed mouth means dental disease is very common. Beyond those, plan for luxating patella (slipping kneecaps), intervertebral disc and back problems, ear infections in the hairy ears, skin-fold and allergy issues, and a breed-associated kidney condition called renal dysplasia. Lifespan is commonly 12 to 15 years, which is good, and most of these problems are manageable with sensible care and a good vet. This is general information, not veterinary advice.

Do Shih Tzus have breathing problems?

Some do, because the Shih Tzu is a brachycephalic breed, meaning it has a shortened muzzle and a compressed airway. This can cause brachycephalic obstructive airway syndrome (BOAS), where narrowed nostrils, an overlong soft palate and a narrow windpipe make breathing harder work. Signs range from mild snoring and snorting to noisy, laboured breathing, poor exercise tolerance, and struggling badly in heat. Not every Shih Tzu is severely affected, and many breathe reasonably well, but the flat face is the reason the breed feels the Sydney summer more than a long-nosed dog. If your Shih Tzu breathes noisily at rest, tires quickly, or you hear a harsh, honking or gasping sound, have your vet assess the airway. Keeping the dog lean helps a lot, because extra weight makes any airway problem worse. Surgery can help significantly affected dogs, and your vet is the person to advise. This is general information, not a diagnosis.

Why are Shih Tzu eyes such a problem, and what is proptosis?

The Shih Tzu has large, round eyes that sit prominently in shallow sockets, and that lovely feature is also its biggest vulnerability. Because the eyes protrude, they are exposed to knocks, scratches and drying, which makes corneal ulcers (painful grazes or sores on the eye surface) common, along with dry eye (reduced tear production) and irritation from hair rubbing on the eye. The most serious risk is proptosis, where a blow to the head or face, or even rough handling, can pop the eyeball forward out of its socket. It looks alarming and it is a genuine emergency: keep the eye moist with saline or a clean damp cloth, do not try to push it back, and get to a vet immediately, because fast treatment gives the best chance of saving the eye. Day to day, watch for squinting, pawing at the eye, redness, cloudiness or discharge, and treat any of these as a reason to see a vet promptly rather than wait. Keeping the hair trimmed away from the eyes prevents a lot of irritation. This is general information, not veterinary advice.

Do Shih Tzus have bad teeth?

Dental disease is one of the most common problems in the breed, and it comes down to the mouth. A Shih Tzu has a normal number of teeth crammed into a small, shortened jaw, so the teeth crowd, overlap and trap food and plaque, which leads to tartar, gum disease and painful infections if nothing is done. Bad teeth are not just a mouth problem: dental disease causes pain, bad breath and can affect general health. The prevention is the same as for any small dog but matters more here: daily tooth brushing with a dog toothpaste is the gold standard, along with vet-recommended dental chews and regular vet dental checks, with a professional clean under anaesthetic when your vet advises. Signs to watch for are bad breath, reluctance to eat hard food, pawing at the mouth, drooling or bleeding gums. Start a dental routine early and keep it up; it is one of the highest-value things you can do for a Shih Tzu. This is general information; your vet is the person to plan dental care.

What are luxating patella and back problems in a Shih Tzu?

Both are structural issues common in small dogs. A luxating patella is a kneecap that slips out of its groove, which shows as an intermittent skip or hop in a back leg, or the dog holding a leg up for a few steps then carrying on. Mild cases are managed with weight control and activity management, while more severe ones may need surgery, and your vet grades and advises. Back problems matter because the Shih Tzu has a slightly longer-bodied build and can develop intervertebral disc disease (IVDD), where a spinal disc bulges or ruptures and presses on the spinal cord. Signs range from a reluctance to jump, a hunched back or yelping when picked up, through to weakness or dragging of the back legs, and sudden back-leg weakness or paralysis is an emergency. You lower the risk by keeping the dog lean, discouraging jumping on and off high furniture, using ramps or steps, and supporting the whole body when you lift. Any sudden change in how the dog moves warrants a prompt vet visit. This is general information, not veterinary advice.

Do Shih Tzus get ear and skin problems?

Yes, both are worth watching. Shih Tzus have hairy, floppy ears that trap warmth, moisture and hair inside the canal, which is exactly the environment ear infections thrive in, and the signs are head shaking, scratching, a smell, redness or discharge. Keep the ears clean and dry, check them regularly, and use only a vet-recommended ear cleaner rather than cotton buds pushed into the canal, and see your vet at the first sign of trouble. On the skin, the breed can develop allergies (itchy, inflamed skin, paw licking and recurrent infections), and the facial skin folds and the fold under the tail can trap moisture and become sore or infected if not kept clean and dry. Wipe and dry the folds regularly, keep the coat clean and mat-free, and see your vet for persistent itching or any sore, smelly skin. Good grooming and good skin health go together, which is why the coat guide and this health guide overlap. This is general information, not a diagnosis.

What is renal dysplasia in Shih Tzus?

Renal dysplasia is a kidney condition that is associated with the Shih Tzu breed. In simple terms, the kidneys do not develop normally, which can lead to reduced kidney function, sometimes in a young dog. It is not something every Shih Tzu has, and we are deliberately not attaching a frequency figure because reliable breed-specific numbers are not something we can verify, but it is a recognised breed-associated concern worth knowing about. The signs of kidney trouble to watch for are increased drinking and urination, poor appetite, weight loss, vomiting and lethargy. If you notice these, especially in a younger dog, see your vet, because a blood and urine test can assess kidney function and early management makes a difference. As with the other conditions here, this is general information; your vet is the person to assess and diagnose any individual dog.

Should a Shih Tzu wear a harness instead of a collar?

Yes, a well-fitted harness is the sensible default for a Shih Tzu. A collar concentrates pressure on the throat and the front of the neck when the dog pulls, and in a small brachycephalic breed that already has a compromised airway, that throat pressure is the last thing you want to add to. A harness spreads the pressure across the chest and keeps it off the neck and windpipe, which makes walks more comfortable and protects the airway. Use the collar for the council registration tag and identification, and clip the lead to a properly fitted harness for walking. This is a simple change that costs little and helps a breed that already works harder to breathe. If your dog coughs, gags or breathes noisily on the lead, mention it to your vet.

How do I keep a Shih Tzu safe in the Sydney heat and from ticks?

Heat is the number one seasonal risk for a Shih Tzu, because the flat face makes cooling by panting far less efficient. In a Sydney summer that means walking only in the cool of the early morning or evening, keeping the dog inside with a fan or aircon on hot, humid days, always providing shade and water, and never, ever leaving the dog in a parked car, which can turn lethal within minutes. Watch for heat stress: heavy, frantic panting that does not settle, drooling, bright red or bluish gums, weakness, distress or collapse, and treat it as an emergency, cool the dog and get to a vet straight away. A short summer clip helps keep the dog cooler. Separately, the paralysis tick is a year-round, potentially fatal risk across the Sydney region, so keep your Shih Tzu on a vet-recommended monthly tick-prevention product without gaps, and check the coat down to the skin after any bush or coastal outing. The tick is easy to miss under a long coat, which is one more reason to keep the coat manageable. This is general information, not veterinary advice.

How long do Shih Tzus live, and how can I help mine stay healthy?

Shih Tzus commonly live around 12 to 15 years, which is a good lifespan, and the way you care for the dog makes a real difference to both the length and the quality of that time. The biggest levers you control are keeping the dog lean (extra weight worsens the airway, the joints, the back and general health), a daily dental routine, keeping the hair trimmed away from the eyes and the eyes protected, careful heat management in the Sydney summer, year-round tick and parasite prevention, keeping ears and skin folds clean and dry, and using a harness rather than a collar. Above all, treat any change (noisy breathing, a sore or cloudy eye, a skipping leg, back stiffness, increased drinking) as a reason to see the vet promptly rather than wait. A rescue Shih Tzu arrives already desexed, vaccinated, microchipped and vet-checked, and adopting an adult often means you know its health history, which is a genuine advantage.
