Shih Tzu Health Issues in Toronto

The most common reason is the breed's flat-faced (brachycephalic) build. A Shih Tzu's short muzzle packs the same soft tissue as a longer-nosed dog into a much smaller space, so narrowed nostrils, a long soft palate, and a tighter airway make snoring, snorting, and noisy breathing normal for the breed at rest. Mild noise is common, but loud or laboured breathing, gagging, or blue-tinged gums are not normal and need a vet. This cluster of signs is called brachycephalic obstructive airway syndrome (BOAS), and it ranges from mild snoring to a condition that surgery can improve. Keep your Shih Tzu lean, use a harness instead of a neck collar, and avoid heat and hard exercise. If breathing seems effortful even when resting or cool, have your vet assess the airway.

Many do to some degree, because the flat face is the defining feature of the breed. Most Shih Tzus live comfortably with mild snoring and snorting, but the same short-muzzle build that gives them their look also narrows the airway, so they tolerate heat and heavy exercise poorly and some develop the more significant end of brachycephalic obstructive airway syndrome (BOAS). Warning signs of the serious end include loud or laboured breathing at rest, frequent gagging or retching, collapse, or blue gums, and those are veterinary matters, not quirks to ignore. A flat-faced breed also carries higher anaesthetic risk, so use a vet experienced with brachycephalic airways for any procedure. Keeping your dog lean, cool, and on a harness are the everyday things that help most.

Lower than owners expect, because a flat-faced dog cannot cool itself efficiently. Dogs shed heat mainly by panting, and a Shih Tzu's narrowed airway makes panting far less effective, so humid Toronto summers are genuinely dangerous for the breed. Avoid walks and play in the midday heat, choose early morning or evening, carry water, and watch for heavy panting, drooling, bright-red gums, wobbliness, or distress, which are early heatstroke signs that need immediate cooling and a vet. Never leave a Shih Tzu in a parked car even briefly, since the interior heats fast and a brachycephalic dog can overheat within minutes. When it is hot and humid, keep your dog indoors with air conditioning or a fan. The AVMA has good warm-weather guidance for flat-faced breeds.

Yes, the eyes are one of the breed's most important health areas. Shih Tzus have large, prominent eyes set in shallow eye sockets, which leaves the surface more exposed and more easily injured than a deeper-set eye. Common issues include corneal ulcers (scratches or damage to the eye surface), dry eye (keratoconjunctivitis sicca, or KCS, where the eye does not make enough tears), cataracts, and progressive retinal atrophy. The most serious is proptosis, where trauma can cause the eye to bulge out of the socket, which is a true emergency needing an immediate vet. Because of all this, treat any eye redness, cloudiness, squinting, pawing at the eye, or discharge as a reason to see a vet promptly. Daily gentle cleaning of the eye area and keeping hair trimmed away from the eyes prevents a lot of trouble.

Yes, and dental disease is one of the most common problems in the breed, so daily care genuinely matters. A Shih Tzu has a small jaw trying to hold a full set of teeth, so the teeth crowd, overlap, and trap food and plaque, which speeds up tartar, gum disease, and eventually painful tooth loss. The most effective prevention is daily tooth brushing with dog toothpaste, started gently and early, plus professional cleanings under anaesthetic when your vet recommends them. Because a flat-faced breed carries higher anaesthetic risk, use a vet comfortable with brachycephalic airways for cleanings, but do not skip them, since untreated dental disease is both painful and a source of infection. Watch for bad breath, reluctance to eat hard food, or pawing at the mouth as signs a check-up is due.

Drop ears plus hair in the ear canal are the reason. A Shih Tzu's hanging ears reduce airflow and hold in warmth and moisture, and hair growing inside the canal traps it further, creating the damp, dark conditions that yeast and bacteria thrive in. Toronto's humid summers make it worse. The prevention is a simple routine: keep the ear hair managed as part of grooming, check the ears weekly for redness, odour, or discharge, dry them after baths or wet weather, and clean with a vet-recommended cleaner as directed. Signs of an active infection include head-shaking, scratching at the ear, a bad smell, or brown discharge, and those should be seen by a vet because ear infections are painful and chronic cases can need medication and point to underlying allergies.

The main orthopedic concerns are patellar luxation and, in small breeds generally, a hip condition called Legg-Calve-Perthes disease. Patellar luxation is a kneecap that slips out of its groove, seen as a skip in the step, an occasional hop, or a leg held up briefly before the dog carries on normally; mild cases are managed and more severe ones may need surgery. Legg-Calve-Perthes involves the hip joint losing its blood supply and is usually seen in young small-breed dogs as lameness or pain in a back leg. Intervertebral disc disease, a back and spine problem, can also occur. Keeping your Shih Tzu lean protects the joints, and any persistent limping, skipping, or reluctance to jump or use stairs is worth a vet visit rather than waiting to see if it passes.

Renal dysplasia is a congenital (present-from-birth) kidney condition that has been associated with the breed, where the kidneys do not develop normally. It is worth knowing about, though it is far less common than the breed's breathing, eye, and dental issues. Affected dogs can show signs of kidney trouble at a young age, such as increased thirst and urination, poor appetite, poor growth, or vomiting. If you notice a young Shih Tzu drinking and urinating much more than normal, that is a reason for a vet visit and bloodwork, since early kidney changes are something a vet monitors and manages. For most owners this is background knowledge rather than a daily worry, but it is part of an honest breed health picture and a good reason to keep up with routine wellness bloodwork as your vet advises.

Shih Tzus commonly live around 10 to 16 years, so this is a long commitment, often well over a decade. That long lifespan is a real strength of the breed, and it is influenced both by genetics and by the everyday things owners control: keeping the dog lean, staying on top of dental care, protecting the eyes, avoiding heat, and keeping current with vet check-ups so problems are caught early. A lean Shih Tzu with attentive daily care and prompt veterinary attention has the best odds of a long, comfortable life. If you are adopting an adult or senior Shih Tzu, you may still have many good years ahead, and giving an older small dog a soft place to land is one of the most rewarding adoptions there is. Plan for the years, and budget for the care they need across them.

For this breed it is genuinely worth considering, and the single most important thing is to enrol early. A Shih Tzu combines airway risk, prominent eyes that are prone to injury and dry eye, and crowded teeth that often need dental work, so the lifetime odds of a real vet bill are higher than for many breeds. Ontario pet insurance for a young, healthy Shih Tzu commonly runs about $40 to $80 per month. The catch that catches everyone: anything already present becomes a pre-existing condition and is excluded, so a policy taken out the week you adopt a healthy young Shih Tzu covers far more than one bought after the first eye ulcer or dental problem appears. Compare providers on annual and per-condition limits, deductibles, and reimbursement, and enrol while your dog is healthy.

Ask the foster or rescue what they have seen day to day: how the dog breathes at rest and after light activity, whether it tolerates warmth, any eye redness, cloudiness, or squinting, the state of the teeth and breath, any ear issues, and any skipping or limping that could point to a knee. Ask for the vet records from the rescue's intake exam, including any dental notes, eye findings, and bloodwork. Then book your own vet visit soon after adoption to set a baseline, and for an adult or senior dog to plan sensible monitoring of the eyes, teeth, and airway. Reputable Toronto rescues are upfront about what they know, and a foster who has lived with the dog is a valuable source of honest information about how it copes with heat, stairs, and daily life.
