Shih Tzu Health Problems: Airway, Eye and Joint Issues

Shih Tzu are predisposed to three clusters of health problems: brachycephalic airway disease caused by the shortened skull, eye conditions that follow from shallow orbits and prominent globes, and orthopedic issues — most commonly medial patellar luxation, intervertebral disc disease and age-related osteoarthritis. Skin-fold dermatitis, ear infections, dental crowding and a handful of inherited internal conditions round out the list. None of these are inevitable in an individual dog, but all of them are worth knowing about before they announce themselves.

What follows is a plain description of what the breed is prone to, what owners usually notice first, and what veterinary medicine does about it — plus an honest look at how owners support soft tissue and joints during recovery and through the aging years.

What a shortened skull changes about breathing

Brachycephalic simply means short-headed. A Shih Tzu's facial bones are compressed, but the soft tissue inside — the palate, the tongue, the nasal turbinates — is not proportionally reduced. That tissue has to fold into a smaller space, and the result is a narrower airway than the dog's body size would suggest.

The components veterinarians look for are well described: stenotic (pinched) nostrils, an elongated soft palate that partly obstructs the airway behind the throat, everted laryngeal saccules, and in some dogs a narrowed trachea. Together these are described as brachycephalic obstructive airway syndrome, or BOAS.

What owners notice first is rarely dramatic. It is snoring, snorting, noisy breathing at rest, gagging after a fast drink, a dog that wants to stop and stand after a short walk, or sleep that keeps getting interrupted. Heat intolerance is a major signal, because panting is a dog's primary cooling system and an obstructed airway makes panting inefficient.

Practical management is unglamorous and genuinely effective: a harness instead of a neck collar so nothing presses on the trachea, strict weight control because fat deposits narrow the airway further, walks in the cooler parts of the day, and no unsupervised time in a hot car or sunroom. Many airlines restrict brachycephalic breeds from cargo travel for exactly these reasons.

When the obstruction is significant, surgical correction — widening the nostrils and shortening the soft palate — is the established veterinary approach, and it is often done alongside a spay or neuter while the dog is already under anesthesia. If your Shih Tzu snores loudly, struggles in summer or tires fast, ask your veterinarian for an airway assessment rather than assuming it is just how the breed sounds.

Eye conditions the breed is known for

The same skull shape that narrows the airway produces shallow eye sockets and prominent, exposed eyes. That exposure drives most of the breed's ophthalmic problems.

Dry eye (keratoconjunctivitis sicca) is common: insufficient tear film leaves the cornea unprotected, producing a sticky discharge, redness and discomfort. Veterinarians diagnose it with a simple tear test and manage it long-term with prescribed ophthalmic medication.

Corneal ulcers happen easily in a breed whose eyes sit forward and whose blink may not fully cover the surface. A Shih Tzu squinting, tearing, holding an eye shut or rubbing at its face is a same-day veterinary visit, not a wait-and-see.

Distichiasis and ectopic cilia — eyelashes growing from the wrong place and abrading the cornea — are reported in the breed and are surgically correctable.

Pigmentary keratitis, a brown pigment creeping across the cornea in response to chronic irritation, is also seen frequently in flat-faced dogs.

Proptosis — the eye displaced forward out of the socket after trauma or rough handling — is a true emergency in any brachycephalic breed because the shallow orbit offers so little mechanical protection.

Cataracts and inherited retinal disease are documented in Shih Tzu lines as well. An annual eye exam is a reasonable baseline, and reputable breeders screen for heritable eye disease.

Skin folds, ears, teeth and the inherited internal conditions

The nasal fold that gives the breed its face also traps moisture, and intertrigo — inflammation of the skin inside a fold — follows if the fold is not kept clean and dry. Allergic skin disease is common in the breed, and allergic dogs tend to get secondary ear infections, made worse by hair-filled ear canals that hold debris.

Dental crowding deserves more attention than it usually gets. A full complement of teeth compressed into a short jaw means rotated and overlapping teeth, retained baby teeth, and plaque collecting in places a tongue cannot reach. Periodontal disease is one of the most consistently diagnosed problems in small brachycephalic breeds, and professional cleaning under anesthesia is the only way to address it properly once it is established.

Several inherited internal conditions are recognised in Shih Tzu: renal dysplasia affecting young dogs, bladder stones, hypothyroidism, portosystemic (liver) shunts, and umbilical hernias. These are far less common than the airway and orthopedic issues, but they are the reason routine bloodwork and urinalysis at wellness visits are worth the money rather than an upsell.

Condition	What owners usually notice first	Typical veterinary approach
Brachycephalic airway syndrome	Snoring, snorting, gagging, heat and exercise intolerance	Airway exam, weight management, surgical correction of nostrils and soft palate when indicated
Dry eye	Thick discharge, redness, squinting	Tear testing, prescribed ophthalmic medication, long-term monitoring
Corneal ulcer	Sudden squinting, tearing, pawing at the eye	Urgent exam with fluorescein stain, prescribed treatment
Skin-fold dermatitis	Odour, redness or moisture in the facial fold	Cleaning routine, medicated products, allergy workup if recurrent
Periodontal disease	Bad breath, tartar, reluctance to chew	Dental radiographs and cleaning under anesthesia, extractions if needed
Medial patellar luxation	Intermittent skipping on a back leg, then normal gait	Orthopedic grading, weight control, rehab, surgery for higher grades
Intervertebral disc disease	Yelping, reluctance to jump, wobbly or weak back legs	Imaging, strict rest and prescribed pain control, or surgery in severe cases
Osteoarthritis	Slow to rise, shorter walks, stiffness after sleep	Diagnosis and a long-term plan including prescribed pain management and rehab

Knees, discs and the mobility picture as a Shih Tzu ages

Orthopedics is where a lot of Shih Tzu owners end up, and it is the part of the breed profile that gets the least airtime.

Medial patellar luxation is the standout. The kneecap slips out of its groove toward the inside of the leg, and the classic sign is a dog that skips on a hind leg for two or three strides then carries on as if nothing happened. Veterinarians grade it from mild to severe, and the grade drives the plan: weight control, muscle-building rehab and monitoring at the mild end, surgical reconstruction of the groove and alignment at the severe end. Chronic low-grade luxation is also a known driver of cartilage wear over years, which is why early grading matters even when the dog seems comfortable.

Intervertebral disc disease is the other one. Shih Tzu are a chondrodystrophic breed — the same genetics that produce short, sturdy legs are associated with discs that degenerate and calcify earlier in life. A dog that suddenly refuses stairs, yelps when lifted, hunches, or drags a hind foot needs veterinary assessment immediately; neurological signs in the back legs are time-sensitive.

Hip dysplasia occurs in the breed too, and in older dogs all of it converges on osteoarthritis: stiffness after rest, shorter walks, hesitation at the sofa, a dog who sleeps more because moving costs more.

A Shih Tzu's breathing, eyes and knees are all downstream of the same thing — a body built small and compact — which is why owners who do best treat management as a daily habit rather than a reaction to a crisis.

Supporting soft tissue and joints through recovery and aging

When a Shih Tzu is recovering from patellar surgery, on crate rest for a disc episode, or simply slowing down at ten years old, the veterinary plan does the heavy lifting: diagnosis, prescribed pain control, imaging and rehab. Nutritional support operates in the space that plan creates — never instead of it.

This is where the peptide category has drawn serious owner interest. pawgen's K9-REPAIR combines BPC-157 and TB-500, dosed by body weight, which matters for a nine-to-sixteen-pound dog whose needs look nothing like a Labrador's.

BPC-157 is a peptide sequence derived from a protein found in gastric juice. Published animal research suggests it may support angiogenesis — the formation of new blood vessels — along with fibroblast activity and the remodeling of tendon, ligament and gut tissue. TB-500 is a synthetic fragment related to thymosin beta-4, a naturally occurring protein involved in actin regulation and cell migration, processes central to how damaged tissue reorganises itself. The mechanisms are the reason owners pair them through recovery windows: blood supply and cell migration are the rate-limiting steps in how connective tissue rebuilds.

These are honest mechanism descriptions, not outcome promises. BPC-157 and TB-500 are not FDA-approved veterinary drugs, the evidence base is largely preclinical, and nothing here should be read as a claim about what will happen to your dog. What can be said plainly is what is in the bottle, that every batch is third-party tested with certificates of analysis published, that dosing is weight-based, that it ships direct to your door, and that it carries a 60-day money-back guarantee.

That transparency is worth contrasting with the kitchen-sink joint chew — fourteen ingredients on the label, a proprietary blend hiding how much of each is actually present, and a glossy bag doing the work that a certificate of analysis should be doing. Ask any brand what is in it and at what amount. If the answer is vague, that is the answer.

Key Takeaways

• Shih Tzu problems concentrate in the airway, the eyes, the skin folds and the joints — all traceable to the breed's compact build.
• Noisy breathing, heat intolerance and exercise fatigue warrant a veterinary airway assessment rather than being dismissed as breed-typical.
• Any squinting, tearing or pawing at an eye is urgent; the shallow orbit gives the cornea very little protection.
• Medial patellar luxation and disc disease are the two orthopedic conditions to know, and both benefit from early grading and strict weight control.
• Dental crowding makes periodontal disease a near-universal management task, not an optional extra.
• K9-REPAIR is the BPC-157 and TB-500 stack owners adopt alongside veterinary recovery plans; research suggests these peptides may support the tissue-repair processes behind healing, and they are not approved veterinary drugs.

For owners comparing formulations, pawgen publishes batch certificates of analysis, lists the full range in the shop, and sets out shipping coverage on its shipping page; product details for K9-REPAIR sit alongside them.

One last framing, because it matters more than anything above: your veterinarian owns the diagnosis and the treatment plan. Imaging, grading, prescribed medication, surgery and rehab are theirs to direct, and nothing — peptides included — belongs in place of them. Talk to your veterinarian before adding any supplement, especially if your Shih Tzu is on prescribed medication, is recovering from a procedure, or is very young, pregnant or nursing. Supplements work in the room that good veterinary care builds.
