Shih Tzu Health Issues: What Owners Should Monitor

Yes. Shih Tzus are prone to a specific, well-documented group of health problems, and nearly all of them trace back to one thing: the shape of the dog. A shortened muzzle, large forward-set eyes, a long body on short legs, a dense double coat and a crowded jaw are the breed's signature, and each feature carries predictable risks. Eye injuries and dry eye, noisy or laboured breathing, heat intolerance, periodontal disease, skin fold and ear infections, luxating kneecaps and spinal disc problems are what veterinarians encounter most often in this breed.

That is not a reason to avoid Shih Tzus. Many live well into their teens as cheerful, deeply attached companions. It does mean the owner's job is different from, say, a Labrador owner's job. The risks here are known in advance, which makes them monitorable — and monitoring is most of the battle.

The breed's build explains most of its health problems

Shih Tzus are brachycephalic: the skull is compressed front to back, but the soft tissue inside it is not. The soft palate, tongue and nasal passages are packed into less room than they were designed for, which narrows the airway. The same compression leaves the eye sockets shallow, so the eyes sit prominently and the cornea is more exposed than in a long-nosed breed.

The body adds a second layer. Shih Tzus carry a comparatively long back on short, slightly bowed limbs — a conformation associated with early degeneration of the spinal discs. The coat grows continuously and mats readily, trapping moisture against skin that already folds across the muzzle.

None of this is a flaw in an individual dog or a sign of a careless breeder. It is breed conformation, which is why these issues appear across pedigrees, rescues and mixes alike. Reputable breeders can reduce risk through eye and knee screening, but they cannot design the shortened muzzle away.

Eyes and breathing: the two systems to watch every day

The single most useful habit a Shih Tzu owner can build is treating small changes — a new squint, a new snore, a skipped step — as information worth bringing to the veterinarian early, because in this breed the gap between 'minor' and 'urgent' can be very short.

Eyes. Prominent globes mean ordinary life carries risk: a swipe from a cat, a run through a shrub, even rubbing on carpet can scratch a cornea. Conditions documented in the breed include corneal ulcers, dry eye (keratoconjunctivitis sicca), stray or misdirected eyelashes, pigmentary keratitis, cataracts and progressive retinal atrophy. Proptosis — the eye displaced forward out of the socket after head trauma — is a genuine emergency in short-faced dogs.

What to act on: squinting, holding an eye closed, pawing at the face, cloudiness, a blue or grey haze, redness, thick discharge, or an eye that looks dull and dry. A squint that lasts more than a few minutes deserves a same-day call, not a wait-and-see weekend.

Breathing. Brachycephalic obstructive airway syndrome covers narrowed nostrils, an overlong soft palate, everted laryngeal saccules and a narrowed windpipe. Signs include snorting, snoring at rest, open-mouth breathing after mild effort, gagging or retching after eating, exercise intolerance and collapse in warm weather. Gums that look blue, grey or very pale are an emergency.

Practical management is unglamorous and effective: keep the dog lean, walk in the cool parts of the day, use a harness rather than a neck collar, and never leave a Shih Tzu in a warm car or a sunny room. Surgical correction of the nostrils and soft palate is a well-established option for dogs whose airway limits their life, and that conversation belongs with your veterinarian, ideally before a crisis rather than during one.

Reverse sneezing — a sudden snorting, honking inhalation — alarms new owners constantly and is usually harmless, but a dog doing it frequently or for long spells should be examined.

Dental, skin and ear care: the maintenance most owners underestimate

A full set of teeth in a shortened jaw means crowding, rotation and retained baby teeth, all of which trap plaque. Periodontal disease is among the most common findings in small brachycephalic breeds, and it is painful long before it is obvious. Dogs rarely stop eating; they just chew on one side, drop kibble, or get grumpy about having their head touched.

Daily brushing at home is the highest-value habit available. Professional cleaning and dental radiographs under anaesthesia are the only way to assess below the gumline. Some owners avoid anaesthesia because the breed is short-faced — a reasonable worry that is better solved by discussing the airway and monitoring plan with your veterinarian than by letting dental disease advance.

Skin and coat problems run close behind. Facial folds hold moisture and debris; yeast and bacterial overgrowth follow. Allergic skin disease is common, usually showing as paw licking, face rubbing, recurring ear infections and a yeasty smell. Dense coat mats quickly behind the ears, under the legs and around the rear, and a tight mat causes real pain and hides sores beneath it.

Ears deserve their own mention: hair-filled, low-set canals with reduced airflow are a setup for recurring otitis. Head shaking, odour, redness or scratching should be examined rather than treated with whatever bottle is in the cupboard.

Less common but documented in the breed: urinary stones, with straining, frequent small urinations or blood — a dog unable to pass urine is an emergency — plus congenital kidney abnormalities, liver shunts and hypothyroidism. These are not inevitable, but they are worth knowing the signs of.

Joints and spine: what changes as a Shih Tzu ages

Two orthopaedic issues dominate. Patellar luxation — the kneecap slipping out of its groove — typically shows as a skipping step, a brief hop, then a return to normal walking. Intervertebral disc disease is the more serious one: the discs in a long-backed, short-legged dog degenerate earlier, and a jump off the sofa can be the final straw. Reluctance to jump, a hunched posture, yelping when picked up, wobbling hind legs or dragging a foot warrants urgent assessment, because outcomes in spinal cases depend heavily on how quickly they are addressed.

Middle-aged and senior Shih Tzus also accumulate ordinary wear: osteoarthritis, soft-tissue strains, reduced muscle mass and a slow contraction of the world — fewer stairs, shorter walks, less interest in play.

What you might notice	What it can point to	What veterinary care usually involves
Intermittent skip or hop on a back leg	Patellar luxation	Orthopaedic exam, grading, weight and muscle plan, surgery in higher grades
Reluctance to jump, yelping, wobbly hind end	Intervertebral disc disease	Urgent neurological exam, imaging, strict rest, medication, sometimes surgery
Stiffness after rest, slower on walks	Osteoarthritis	Exam, imaging, prescribed pain control, rehab and weight management
Squinting, cloudiness, discharge	Corneal ulcer, dry eye, other ocular disease	Stain test, tear testing, prescribed eye medication, referral if needed
Snoring at rest, gagging, poor heat tolerance	Brachycephalic airway syndrome	Airway assessment, weight plan, surgical correction where indicated
Bad breath, chewing on one side	Periodontal disease	Dental radiographs and cleaning under anaesthesia, extractions as needed

If your dog is on prescribed pain medication, rehabilitation or post-operative rest, that plan stays exactly as written. Nothing you add at home replaces it.

Behaviour, temperament and what owners trade notes about online

Search any owner forum and the same threads repeat: eye emergencies at 11pm, housetraining that takes longer than expected, dental estimates, food sensitivities, and the dog that follows one person from room to room.

Temperament-wise, Shih Tzus were bred as companions and show it. They are sociable, confident with people, and often poorly suited to long days alone — separation distress is a frequent complaint. Housetraining genuinely can take longer; the usual culprits are a small bladder, inconsistent schedules and reinforcement that arrives too late, not stubbornness. Many are enthusiastic about food and gain weight easily, which directly worsens both airway and joint problems.

The most important behavioural point is diagnostic: in this breed, a behaviour change is often the first sign of pain. A dog that stops greeting at the door, growls when lifted, sleeps more, or suddenly refuses stairs is usually telling you something physical. Mention it at the exam — your veterinarian would far rather hear about a vague change early than a crisis later.

Supporting mobility and recovery alongside veterinary care

Once diagnosis and treatment are in place, most owners want to support the recovery window itself. This is where the supplement aisle gets noisy. Plenty of chews list a dozen ingredients at trace amounts, hide quantities behind a proprietary blend, and publish no third-party testing at all — marketing over evidence.

pawgen takes a narrower approach. K9-REPAIR is a two-peptide formulation for dogs: BPC-157 and TB-500. BPC-157 is a synthetic peptide studied for its role in soft-tissue repair processes, including new blood vessel formation and tendon and ligament cell behaviour. TB-500 is related to thymosin beta-4, a naturally occurring protein studied for its role in cell migration and tissue remodelling. This is promising, actively developing science that a growing number of owners are adopting through recovery periods, and research suggests these mechanisms sit squarely in the tissue-repair space. BPC-157 and TB-500 are not FDA-approved veterinary drugs, and nothing here should be read as a claim that any product addresses a specific condition in your dog.

What pawgen can state plainly: K9-REPAIR is dosed by body weight, third-party tested with certificates of analysis available, shipped direct to your door, and backed by a 60-day money-back guarantee. Whether it belongs in your dog's recovery plan, and how it fits around prescribed medication, is a conversation to have with your veterinarian — particularly for puppies, pregnant or nursing dogs, where the answer is always a veterinary one rather than a number from the internet.

Key Takeaways

• Shih Tzus are prone to health problems driven by conformation: short muzzle, exposed eyes, long back, dense coat, crowded jaw.
• Eyes and airway need daily attention; a persistent squint or laboured breathing in heat is urgent, not routine.
• Dental disease, skin fold infections and ear infections are the highest-frequency maintenance issues — brushing and grooming genuinely change outcomes.
• Patellar luxation and disc disease are the orthopaedic risks; sudden back pain or hind-limb weakness needs same-day assessment.
• Keeping the dog lean is the single intervention that helps the airway, the knees and the spine at once.
• Behaviour changes are frequently the first visible sign of pain in this breed.

Your veterinarian owns the diagnosis and the treatment plan — the eye exam, the airway assessment, the dental radiographs, the imaging, the prescriptions, the surgical decisions. Supplements and peptides operate only in the space that proper veterinary care creates, supporting a dog through the recovery window that good medicine has already opened.
