The Shih Tzu is a toy breed with a surprisingly ancient and aristocratic history. Developed in the imperial palaces of China specifically as a companion for royalty, the breed has never had any working purpose beyond companionship — and more than a thousand years of selective breeding for exactly that purpose show. Few breeds are as genuinely devoted to human company, as content to sit in a lap for hours, and as remarkably portable as the Shih Tzu, whose name translates loosely as "little lion dog."
This guide covers the honest picture of life with a Shih Tzu, including the breed's brachycephalic (flat-faced) anatomy and the real respiratory and thermoregulatory considerations that come with it. Shih Tzus are wonderful dogs, but their facial structure creates specific welfare considerations that every prospective owner deserves to understand clearly before purchase. What follows covers temperament, extensive grooming needs, exercise, realistic health profile, training, costs, and clear-eyed pros and cons. Our veterinary editorial team has compiled this guide using breed standards from the American Kennel Club (AKC), welfare research from the Universities Federation for Animal Welfare (UFAW), and health screening protocols from the Orthopedic Foundation for Animals (OFA).
History and Origin
The Shih Tzu's ancestry traces back more than a thousand years into the Tibetan and Chinese imperial courts. Tibetan lamas likely bred early small companion dogs that were presented as gifts to Chinese emperors, where Chinese breeders — particularly during the Ming and Qing dynasties — refined them into the long-coated, short-faced lap dogs that survived as palace pets. The breed's modern form was stabilized in the late 19th and early 20th centuries, and the dogs that reached Western breeding programs descended from a tiny number of imperial breeding pairs.
The breed was nearly lost during the political upheavals of 20th-century China — at one point it is believed only a handful of foundation breeding dogs remained. British and Scandinavian breeders preserved the line through the mid-century, and the Shih Tzu was recognized by the AKC in 1969. The breed has consistently ranked in the top 20 AKC breeds for decades, beloved for its compact size, long glamorous coat, and genuinely affectionate disposition.
Temperament and Personality
Centuries of selection for companionship show clearly. The Shih Tzu is affectionate, outgoing, confident, and genuinely people-focused in a way that few breeds match. The breed standard describes "lively, alert, outgoing, with distinct arrogance and a well-balanced temperament" — and living with a Shih Tzu does feel like cohabiting with a small, dignified, endlessly friendly aristocrat who has no interest in your productivity.
Shih Tzus generally get along well with children, provided the children are old enough to handle a small dog gently; the breed is too delicate for rough-and-tumble play and can be injured by being dropped or squeezed. With other dogs and cats they are typically sociable rather than dominant. Toward strangers they are confident and friendly rather than suspicious, making them poor watchdogs by disposition though their alert barking may still announce visitors. Separation anxiety is common — this is a breed that was literally never meant to be alone.
Exercise and Mental Stimulation
Compared to working or sporting breeds, exercise needs are modest: 30 minutes of daily activity split across two or three short walks, plus some indoor play, meets the typical Shih Tzu's needs well. The breed enjoys short walks, light fetch, and exploring new environments at a leisurely pace. Long hikes, hard running, or intense exercise are not appropriate — partly because of size, but primarily because the brachycephalic airway limits how efficiently the dog can breathe and cool itself.
Heat tolerance is genuinely poor. Shih Tzus overheat quickly in warm weather, especially in humidity, and heatstroke risk is significant even during routine walks on hot days. Schedule outdoor activity for cool mornings and evenings during summer, carry water, and never leave a Shih Tzu in a warm car or direct sun. Mental enrichment through puzzle feeders, scent games, and basic trick training matters more than physical endurance for this breed.
Grooming
The Shih Tzu coat is among the most demanding in the dog world. In a full show coat, the hair grows continuously and reaches the floor, requiring daily brushing to prevent mats and regular baths to keep clean. Most pet owners keep their Shih Tzus in a shorter "puppy clip" or "teddy bear trim" that is far more practical — coat length of 1 to 2 inches brushed thoroughly every 2 to 3 days plus a professional groom every 4 to 6 weeks.
Face care is daily. The hair around the eyes must be trimmed or tied up to prevent corneal irritation, tear staining cleaned daily with warm water, and the facial folds near the nose checked and dried to prevent dermatitis. Ears (which are heavily haired and floppy) need weekly cleaning and plucking of inner-ear hair by a groomer. Nails grow fast and need trimming every 3 to 4 weeks. Dental care is critical: toy breeds in general and Shih Tzus in particular are prone to severe dental disease, so daily tooth brushing and regular professional dental cleanings are genuinely necessary, not optional.
Common Health Issues
The Shih Tzu is one of the most common brachycephalic breeds in pet homes, and responsible ownership begins with understanding what that anatomy means. UFAW and a growing consensus of veterinary surgeons and welfare bodies have increasingly raised concerns about the welfare implications of extreme brachycephaly. Moderate-muzzled Shih Tzus bred for functional airways fare much better than very flat-faced show dogs — look for breeders who prioritize open nostrils, reasonable muzzle length, and documented unimpaired breathing.
| Condition | Typical Age of Onset | Prevention / Management |
|---|---|---|
| Brachycephalic Obstructive Airway Syndrome (BOAS) | Any age | Choose moderate-muzzled lines; weight control; avoid heat/stress; surgical correction if severe |
| Dental Disease | Young adult onward | Daily brushing; annual veterinary cleanings; chew-based adjuncts |
| Patellar Luxation | Young adult | OFA patella screening; lean body condition; surgery if grade III-IV |
| Intervertebral Disc Disease (IVDD) | Middle age | Avoid jumping from heights; ramps for furniture; weight control |
| Eye Conditions (proptosis, corneal ulcers, dry eye) | Any age | Keep facial hair trimmed; prompt vet attention for any eye issue; tear film testing |
| Hip Dysplasia | 1-2 years onward | OFA/PennHIP screening; healthy weight; appropriate exercise |
| Portosystemic Shunt (liver shunt) | Young puppies | Bile acids testing before breeding; dietary management or surgical correction |
| Heat stroke | Any age | Avoid warm-weather exertion; never leave in vehicles; recognize early signs |
On brachycephaly specifically: prominent eyes that are more exposed to trauma, narrowed nostrils that restrict airflow, elongated soft palates that can obstruct breathing, and a shorter skull that crowds dental alignment are all consequences of the flat face. Not every Shih Tzu will have serious BOAS, but every Shih Tzu owner should know the symptoms (snoring, snorting, labored breathing during mild exercise, cyanotic gums under stress) and work with a veterinarian who takes brachycephalic welfare seriously. Surgical correction of BOAS is well-established and life-changing in affected dogs — do not wait if symptoms appear.
Diet and Nutrition
Adult Shih Tzus typically eat about half a cup to one cup of high-quality dry food daily, split into two meals. Small-breed formulas have appropriate kibble size for the short muzzle and caloric density for the small stomach. Puppies need three to four small meals until about six months. Choose WSAVA-compliant manufacturers and avoid boutique grain-free diets given broader DCM concerns across breeds.
Weight control is critical. An extra pound on a 12-pound dog is the proportional equivalent of 15+ pounds on a person, and every ounce of excess weight worsens brachycephalic breathing, patellar luxation risk, and joint stress. Measure meals with a cup or scale rather than free-feeding. Use a portion of the daily allowance for training treats rather than adding to it.
Training
Shih Tzus are intelligent but have a reputation for being stubborn — which usually means they are confident, independent, and less food-obsessed than retrievers. Positive reinforcement works well, but training sessions should be short (5 to 10 minutes), fun, and varied. Harsh methods are completely unnecessary with a toy companion breed and tend to damage the bond.
House training is the area most new owners underestimate. Toy breeds in general, and Shih Tzus specifically, take longer to house train than larger dogs — their small bladders and the sometimes-lax supervision that comes with a tiny dog both contribute. Consistent crate training, scheduled outings every two hours for puppies, and patient reinforcement of outdoor elimination over months (not weeks) is realistic. Beyond house training, basic manners, a reliable recall, and leash walking are all achievable; many Shih Tzus also excel at trick training and canine freestyle.
Is This Breed Right For You?
Strong fit: households with a person home most of the day; apartments, condos, and senior-friendly homes; families with older children who can handle small dogs respectfully; owners committed to daily coat care and regular professional grooming; homes in temperate climates or with strong climate control.
Poor fit: households with toddlers or rough young children; very hot climates without air conditioning; owners seeking a low-grooming companion; active households wanting a jogging or hiking partner; families gone 10+ hours a day; buyers unwilling to prioritize moderate-muzzled, health-tested breeders over extreme flat-faced show styling.
Cost of Ownership
Shih Tzu puppies from responsible breeders typically run $1,000 to $2,500. Rescue adoption, often through breed-specific rescues, runs $200 to $500 and is an excellent option. Annual costs land $1,500 to $2,800 for food, routine veterinary care, professional grooming (a major line item — $60 to $100 every 4 to 6 weeks), dental prophylaxis, insurance, and preventatives. Lifetime cost estimates reach $25,000 to $45,000 over the breed's typical 10-to-18-year life, with brachycephalic surgery or major dental work pushing the upper end in affected dogs.
Frequently Asked Questions
Are Shih Tzus hypoallergenic? No dog is fully hypoallergenic, but Shih Tzus shed very little because their coat is hair rather than fur. Many allergy sufferers tolerate the breed better than double-coated shedders, though individual responses vary — spend time with the breed before committing.
How long do Shih Tzus live? AKC data places the breed at 10 to 18 years, with 12 to 15 being typical. Lean body condition, dental care, airway health, and protection from heat are the strongest predictors of a long life.
Are they good apartment dogs? Yes, exceptionally well-suited for apartments. Low exercise needs, small size, and companionable nature make them popular with urban and senior owners.
Do they bark a lot? Moderately. They announce visitors and can be vocal when excited or lonely, but they are not persistent barkers in well-socialized, well-cared-for homes.
Is the flat face really a problem? It can be. Moderate-muzzled dogs bred for functional airways live comfortably; extremely flat-faced show-style dogs more often struggle with breathing, heat, and eye problems. Choose breeders who prioritize airway health and be willing to pursue surgical correction if your dog shows BOAS symptoms.
