Shih Tzu Health Issues

The Shih Tzu-specific conditions every Calgary owner should know — led by brachycephalic breathing problems, eye proptosis and corneal ulcers, severe dental disease, IVDD, and renal dysplasia

13 min read · Updated May 6, 2026

The short answer

Five Shih Tzu-specific conditions Calgary owners must know: brachycephalic airway syndrome ($3,500–$6,500 BOAS surgery), eye conditions (proptosis emergency, dry eye, corneal ulcers, cataracts), severe dental disease (~85% by age 3, cleanings every 6–12 months), IVDD ($5,000–$10,000 surgery), and renal dysplasia (kidney disease appearing by age 2–5). Also share with toy breeds: tracheal collapse (always harness, never collar), luxating patella, allergies, hypothyroidism. Pet insurance pays for itself for this breed — Shih Tzu lifetime vet costs frequently exceed $20,000 due to brachycephalic, eye, dental, and orthopedic risks combined.

Before any Shih Tzu surgery or dental cleaning

Tell your vet your dog is brachycephalic. Shih Tzus are at significantly elevated anesthesia risk due to their compressed airway anatomy. Recovery requires careful monitoring — many BOAS-affected Shih Tzus need intubation extended past extraction, oxygen support during recovery, and head elevation post-op. Ask: do you have brachycephalic anesthesia experience? If your vet hasn't handled many flat-faced breeds for surgery, ask for a referral to a Calgary specialty clinic before scheduling.

Are Shih Tzus brachycephalic and what does that mean?

Yes — Shih Tzus are a brachycephalic (flat-faced, short-snouted) breed alongside Pugs, French Bulldogs, Boston Terriers, and Pekingese. Their compressed skull structure causes Brachycephalic Obstructive Airway Syndrome (BOAS): elongated soft palate, narrow nostrils (stenotic nares), everted laryngeal saccules, hypoplastic trachea. Symptoms range mild (snoring, snorting, exercise intolerance, heat sensitivity) to severe (laboured breathing, gum colour changes during exercise, collapse). Calgary BOAS surgery (soft palate trim + nostril widening): $3,500–$6,500 at general practice, more at specialty clinics (VCA Canada West, Western Veterinary Specialist Centre). Many Shih Tzus do well with management alone (avoid heat, harness not collar, keep weight low, no high-intensity exercise), but moderate-to-severe BOAS benefits significantly from surgery before age 4.

Calgary heat (May–September) is genuinely dangerous for moderate-to-severe BOAS Shih Tzus. Walks before 9 AM or after 7 PM in summer, never ride in a hot car, watch for excessive panting and gum colour changes.

What eye problems do Shih Tzus have?

Multiple. Shih Tzus have prominent eyes due to shallow eye sockets — beautiful but vulnerable. Common problems:
(1) Proptosis — eyeball pops out of socket from minor head trauma. True emergency: cover eye with damp cloth, ER vet within 30 minutes. Calgary repair surgery: $1,500–$3,000.
(2) Corneal ulcers from facial hair rubbing the eye — trim hair short around eyes, treat with prescription drops.
(3) Dry eye / KCS — chronic insufficient tear production, lifetime cyclosporine drops (~$30/month).
(4) Cataracts — common in seniors, surgery $3,000–$5,000/eye.
(5) Cherry eye — third eyelid gland prolapse, surgical replacement ~$800/eye.
(6) Distichiasis — extra eyelashes scratching cornea.

Daily eye care: wipe corners with damp soft cloth or sterile saline pad, keep facial hair trimmed back, schedule annual eye exams. Watch for redness, squinting, excessive tearing, or blue/cloudy appearance — all warrant a same-day vet visit.

How serious is dental disease in Shih Tzus?

Severe and almost universal. Approximately 85% of Shih Tzus have dental disease by age 3 — among the highest rates of any breed. Cause: small jaw with the standard 42 dog teeth means severe overcrowding, retained baby teeth, and food trap pockets. Brachycephalic skull shape compounds the crowding. Shih Tzus often need professional dental cleanings every 6–12 months (vs every 1–2 years for most breeds), with extractions of badly diseased teeth — many seniors end up with no teeth at all and do fine with kibble softened in water. Calgary dental cleaning cost: $500–$1,500 depending on extractions. Lifetime dental care for a Shih Tzu often runs $5,000–$10,000+. Prevention: daily tooth brushing with dog-safe toothpaste from puppyhood, VOHC-approved dental chews, regular vet exams.

What is IVDD in Shih Tzus?

Intervertebral Disc Disease (IVDD) is herniation or rupture of the cushioning discs between vertebrae. Shih Tzus are predisposed due to their long-back/short-leg body shape (chondrodystrophic build, similar to Dachshunds and Corgis). Symptoms: reluctance to jump, hunched back, yelping when picked up, sudden hindlimb weakness or paralysis. IVDD is a vet emergency when paralysis or loss of bladder control develops — surgical decompression within 24–48 hours dramatically improves outcomes. Calgary surgical IVDD treatment: $5,000–$10,000+ at specialty neurology (Western Veterinary Specialist Centre, VCA Canada West). Conservative management for mild cases: 4–6 weeks strict crate rest, anti-inflammatories, gradual return to activity. Prevention: don't let Shih Tzus jump on/off furniture (use ramps), keep them lean, support their back when picking up (one hand under chest, one under hindquarters).

What is renal dysplasia in Shih Tzus?

Renal (kidney) dysplasia is a congenital condition where kidneys develop abnormally — Shih Tzus are one of the highest-risk breeds. Symptoms typically appear age 2–5: increased thirst and urination, weight loss, vomiting, lethargy, pale gums, ammonia-like breath. Diagnosis: bloodwork (elevated BUN, creatinine, SDMA), urinalysis (low specific gravity), ultrasound (small irregular kidneys). Treatment: prescription kidney diet (Hill's k/d, Royal Canin Renal), subcutaneous fluids if dehydrated, phosphate binders, blood pressure medication. There is no cure — only management. Calgary cost: $200–$500 initial diagnostic workup, $150–$300/month ongoing care. Many Shih Tzus with renal dysplasia live 1–3 years post-diagnosis with good management.

Shih Tzu rescues sometimes screen for kidney disease before adoption — ask if a senior Shih Tzu has had recent bloodwork.

Do Shih Tzus get hypothyroidism?

Yes — common in Shih Tzus. Typically appears age 4–10. Symptoms: weight gain despite normal diet, lethargy, dry/flaky skin, hair loss (often symmetrical on flanks), cold intolerance, slow heart rate, recurrent skin and ear infections. Diagnosis: thyroid panel bloodwork (T4, free T4, TSH). Treatment: daily oral levothyroxine ($15–$30/month) is highly effective — most Shih Tzus return to normal energy and weight within 4–6 weeks. Lifelong medication, recheck bloodwork every 6 months. If your senior Shih Tzu is gaining weight and slowing down, ask your vet for a thyroid panel before assuming “old age.”

Do Shih Tzus have skin and food allergies?

Frequently. Shih Tzus are one of the higher-risk breeds for atopic dermatitis (environmental allergies) and food allergies. Symptoms: itchy ears with recurrent infections, paw licking and chewing, red belly/groin/armpits, hair loss in patches, hot spots. Triggers: environmental (pollen, dust mites, mold) or food (chicken, beef, dairy, wheat are most common). Diagnosis: elimination diet trial (8–12 weeks on novel-protein hydrolyzed diet, $80–$120/bag), allergy serology testing ($300–$600). Treatment: Apoquel (~$70/month), Cytopoint injections (~$80/month), medicated shampoos, fatty acid supplementation, strict avoidance of food triggers. Calgary specialty veterinary dermatology: Western Veterinary Specialist Centre. Allergies are lifelong and management-focused, not curable.

Why do Shih Tzus need a harness instead of a collar?

Three reasons: (1) brachycephalic airway anatomy means any tracheal pressure is dangerous, especially during exercise. (2) Shih Tzus are prone to mild tracheal collapse alongside Pomeranians and Yorkies — collar pressure accelerates the damage. (3) Eye proptosis risk — sudden leash jerk on a collar can cause eye to pop out of socket due to shallow eye sockets and short snout structure. Use a back-clip or vest-style harness for daily walks. Front-clip harnesses are fine for training but watch for chest pressure. Collars are okay for ID tags only, never for leash attachment. See our Pomeranian health guide for the full tracheal collapse breakdown — same condition, same management.

Do Shih Tzus get luxating patella?

Yes — estimated 15–25% have some degree. Graded 1–4. Calgary luxating patella surgery: $3,000–$5,000 per knee. Many Grade 1–2 cases managed without surgery using weight control, joint supplements, limited high-impact activity (no jumping off furniture — also reduces IVDD risk). See the Pomeranian health guide for full grade-by-grade breakdown — toy breeds share this issue.

How does Calgary weather affect Shih Tzus?

Significantly. Brachycephalic breeds are hit hard at both temperature extremes.

Hot weather (above 22°C): Shih Tzus cannot pant efficiently due to compressed airway — heat exhaustion happens fast. Avoid midday walks May–September. Watch for excessive panting, gum colour changes, collapse.

Cold weather (below 5°C): brachycephalic dogs can't warm air efficiently before it hits the lungs. Below -10°C: limit walks to 10–15 minutes, use a winter coat, wipe paws after to remove salt.

Calgary chinook winds (rapid temperature swings) trigger flare-ups in some allergic Shih Tzus. Dry winter air worsens dry eye and skin conditions.

What should I keep on hand for a Shih Tzu emergency?

A Shih Tzu emergency kit:
(1) Saline eye flush and clean gauze (corneal ulcers and proptosis events)
(2) Pet first aid kit with vet wrap, antiseptic, tweezers
(3) Phone numbers programmed in: regular vet, Calgary 24-hour emergency clinic (Paramount, VCA Canada West, CARE Centre), Pet Poison Helpline 1-855-764-7661
(4) Current photo of your dog with weight noted (Shih Tzu weight matters for medication dosing)
(5) Carrier or harness within easy reach
(6) Pet insurance card or vet financing info (CareCredit, ScratchPay) — brachycephalic surgery, IVDD surgery, and proptosis repair often run $3,000–$10,000+

Should I get pet insurance for my Shih Tzu?

Yes — Shih Tzus are one of the breeds where insurance reliably pays for itself. The combination of brachycephalic surgery risk ($3,500–$6,500), IVDD surgery ($5,000–$10,000), eye conditions (proptosis $1,500–$3,000, cataract $3,000–$5,000/eye, dry eye lifetime drops), luxating patella surgery ($3,000–$5,000 per knee), dental cleanings every 6–12 months ($500–$1,500 each), allergy management ($800–$1,500/year), and renal dysplasia management means most Shih Tzus will exceed their lifetime premium contributions in vet costs. Enrol before symptoms appear — pre-existing conditions are excluded across every Canadian provider. Calgary average: $35–$60/month for a young healthy Shih Tzu with $300 deductible / 80% coinsurance / $15,000 limit.

Frequently Asked Questions

Are Shih Tzus brachycephalic?

Yes. Compressed airway causes BOAS (snoring, exercise intolerance, heat sensitivity). Calgary BOAS surgery $3,500–$6,500 at specialty. Avoid heat, harness not collar, keep weight low.

Shih Tzu eye problems?

Proptosis (eyeball pops out, ER within 30min, $1.5–$3K), corneal ulcers, dry eye/KCS (lifetime drops), cataracts, cherry eye, distichiasis. Daily wipe + trim facial hair + annual eye exams.

~85% by age 3. Cleanings every 6–12 months ($500–$1,500 Calgary). Lifetime dental $5K–$10K+. Daily brushing essential.

IVDD in Shih Tzus?

Long back, short legs — predisposed. Calgary surgery $5K–$10K+. Use ramps, keep lean, support back when picking up.

Renal dysplasia?

Congenital kidney disease. Symptoms by age 2–5: thirst, weight loss, vomiting. Manage with prescription kidney diet, fluids, meds. 1–3 year prognosis post-diagnosis.

Hypothyroidism?

Common, age 4–10. Weight gain, lethargy, hair loss. Daily levothyroxine $15–$30/month, lifelong, highly effective.

Skin/food allergies?

Frequent. Itchy ears, paw licking, hot spots. Apoquel ~$70/month, Cytopoint ~$80/month. Lifelong management.

Harness or collar?

Always back-clip harness. Brachycephalic + tracheal collapse risk + eye proptosis risk. Collar for ID only.

Luxating patella?

15–25% have some degree. Surgery $3,000–$5,000/knee Calgary. Grade 1–2 often managed without surgery.

Calgary weather?

Hot >22°C: heat exhaustion fast, avoid midday walks. Cold <-10°C: short walks, winter coat. Chinook winds trigger allergy flare-ups.

Emergency kit?

Saline eye flush, first aid, ER vet numbers, Pet Poison Helpline 1-855-764-7661, photo + weight, carrier, insurance/financing.

Pet insurance for Shih Tzus?

Yes — reliably pays for itself. Brachycephalic + IVDD + eye + dental + orthopedic + allergy risks combine to exceed lifetime premiums. Calgary $35–$60/month young healthy Shih Tzu.

Reverse sneezing (snorting/honking)?

Very common in brachycephalic Shih Tzus. 5–30 second snorting episodes, harmless. Calm + stroke throat + cover nostrils to trigger swallow. Worry only if >60s, blue gums, or pattern shifts to chronic dry honking (tracheal collapse).

Picky eater Shih Tzu?

Dental pain until proven otherwise (~85% have dental disease). Vet exam first. If dental is clear: 48-hour treat reset, scheduled meals, walk away if uneaten. Bone broth or canned topper. Refusing food >24 hours = vet visit.

Is my Shih Tzu overweight?

Lean target 10–13 lbs male, 9–12 lbs female. Should feel ribs easily, see waist tuck. Extra weight worsens BOAS, IVDD, patella, anesthesia. Measure kibble, treats <10% of calories.
