Shih Tzu

The Shih Tzu ("lion dog") has roots in Tibetan monasteries, where small dogs were bred as companions and possibly as living hot water bottles. These dogs were gifted to Chinese emperors, who refined them in the imperial palace. DNA analysis confirms the Shih Tzu as one of the most ancient dog breeds, closely related to wolves despite appearances.

The breed nearly went extinct during the Chinese Communist Revolution. All modern Shih Tzus descend from just 14 dogs — seven pairs — that were used to rebuild the breed in the mid-20th century. This genetic bottleneck shapes the breed's health profile today. The AKC recognized the Shih Tzu in 1969.

Palace Dog to People's Dog

Despite their imperial origins, Shih Tzus have always been companion dogs — not hunters, not herders, not guardians. They were bred for one purpose: being pleasant to be around. This 2,000-year focus on companionship produced a breed that genuinely excels at it.

Shih Tzus are among the most friendly, outgoing toy breeds. Where Chihuahuas can be one-person dogs and Yorkies can be feisty, Shih Tzus are genuinely sociable with almost everyone. They approach strangers with curiosity rather than suspicion and generally get along well with other dogs.

What Makes Them Great

Shih Tzus are adaptable, affectionate, and low-drama. They don't require enormous exercise, they're not destructive, and they're not neurotic. They're content to sit with you, follow you from room to room, and be included in whatever you're doing. Their calm, pleasant nature makes them excellent therapy dogs.

What Surprises New Owners

The grooming commitment. People fall in love with the flowing coat and don't realize it requires daily maintenance. Without regular brushing, the coat mats to the skin within days, causing pain and skin damage. Many new owners switch to a short puppy clip within the first few months.

They can also be surprisingly stubborn about house training. Shih Tzus are not eager to please in the way retrievers are, and convincing them that going outside in the rain is preferable to the warm carpet can be a project.

Companion Drive

The Shih Tzu's primary instinct. They want to be with their people and are happiest when included in daily activities. They're not as clingy as some breeds but definitely prefer company to solitude.

Alert Barking

Moderate. Shih Tzus will alert to the doorbell and unusual sounds but are generally less vocal than Pomeranians, Chihuahuas, or Yorkies. They're not typically nuisance barkers.

Prey Drive

Very low. Shih Tzus show minimal interest in chasing. They coexist peacefully with cats, small pets, and other dogs. This makes them excellent for multi-pet households.

Play Style

Gentle and social. Shih Tzus enjoy moderate play — tug, fetch with small toys, and wrestling with appropriately sized dogs. They tire relatively quickly and alternate play with rest periods.

Puppy (0–6 months)

Shih Tzu puppies are playful, mouthy, and need gentle handling around their prominent eyes. Begin grooming routines immediately — daily brushing, handling feet and face — so they accept it as normal. Socialization during this window produces the confident, friendly adult the breed is known for.

Adolescent (6–14 months)

The coat transitions from puppy to adult texture, and matting becomes a bigger challenge. Stubbornness may increase. Consistent training and grooming routines through adolescence prevent lifelong issues.

Adult (1.5–9 years)

A long, stable phase. Shih Tzus are consistent, easygoing adults. Grooming and eye care are the primary ongoing needs. Weight management matters — overweight Shih Tzus have more breathing difficulty and joint problems.

Senior (10+ years)

Eye conditions often progress — cataracts and dry eye become more common. Kidney function should be monitored. Many Shih Tzus remain comfortable and engaged well into their mid-teens with appropriate senior care.

The Shih Tzu's health profile is moderate compared to other brachycephalic breeds. Their flat faces are less extreme than Pugs or French Bulldogs, resulting in generally less severe airway compromise. Eye conditions are the breed's most consistent health challenge, followed by joint issues and kidney concerns.

The breed's narrow genetic base (all modern Shih Tzus descend from 14 dogs) means some conditions are more prevalent than they might otherwise be. Responsible breeders track their lines carefully and test for known hereditary conditions.

Overall, Shih Tzus are a relatively healthy breed for their type. They live long lives (10-18 years) and most enjoy good quality of life with appropriate care. For breeding requirements, see our Health Testing Before Breeding guide.

Exercise

20-30 minutes daily. Short walks and gentle play. Shih Tzus are not athletic dogs and don't need vigorous exercise. Avoid heat — their brachycephalic features make them heat-sensitive. Many Shih Tzu owners find that a few short walks plus some indoor play satisfies their dog completely.

Grooming

The breed's most demanding care category. Full coat: daily brushing, weekly baths, regular topknot maintenance. Most pet owners choose a puppy clip — trimmed short every 4-6 weeks with weekly brushing between grooms. Either way, expect significant grooming time or expense. Keep facial hair trimmed or tied up to prevent eye irritation. Clean ears regularly — hair grows in the ear canal and traps moisture.

Eye Care

Daily eye checks and cleaning. Wipe tear stains, check for redness or discharge, and keep hair away from the eyes. Corneal ulcers are common and can progress rapidly — any squinting or eye cloudiness warrants an immediate vet visit.

Training

Positive reinforcement with short sessions. Shih Tzus respond to food rewards and gentle praise. They can be stubborn — patience is more effective than repetition. House training may take longer than average; consistency and a regular schedule help.

Families with Children

Good match for families with gentle children. Shih Tzus are sturdier and more patient than many toy breeds. Teach children to be careful around the eyes and to handle the dog gently.

Other Pets

Excellent. Shih Tzus are among the most sociable toy breeds with other animals. Low prey drive means they coexist well with cats and other small pets.

Apartments vs. Houses

Ideal apartment dogs. Low energy, moderate barking, compact size. They adapt well to any living situation as long as they have companionship and climate control.

Not Right for You If...

• You don't want significant grooming responsibility
• You want an active, athletic companion
• You live in a hot climate without AC
• You want a highly trainable, eager-to-please dog
• Eye care maintenance sounds like too much work

Breeding Shih Tzus requires eye, patella, and hip evaluations alongside understanding the breed's narrow genetic base and brachycephalic delivery considerations.

Health Clearances Before Breeding

The American Shih Tzu Club recommends CAER eye exams, OFA patella evaluation, and OFA hip evaluation. Thyroid screening and renal screening are also recommended given the breed's predisposition.

Pregnancy & Whelping

Shih Tzu pregnancies average 63 days from ovulation. Litters typically range from 2-5 puppies. C-section rates are moderate — brachycephalic puppy heads and small dam size can complicate delivery. Newborn Shih Tzu puppies typically weigh 120-200 grams (4-7 oz).

The Animal Weight Tracker monitors individual puppy growth, and the Whelping Date Calculator helps plan delivery timing.

Shih Tzu Pregnancy Overview

Shih Tzu pregnancies often progress quietly, particularly in the early weeks. As a small, compact breed with a brachycephalic skull structure, Shih Tzus sit at an intersection where pregnancy is frequently uncomplicated, yet margins for error remain relatively narrow. Subtle changes can matter more than they might in larger breeds.

Gestation length typically averages around sixty-three days from ovulation, though variation of several days in either direction can still fall within a normal range. Experienced breeders tend to view pregnancy as a window rather than a fixed due date, interpreting timing alongside behavior, comfort, and physical progression.

Early pregnancy signs in Shih Tzus are often minimal. Appetite, activity, and body shape may remain unchanged through the first half of gestation. Because visible indicators can be subtle, early baseline records play an important role in interpreting later changes. For a complete guide to pre-breeding evaluations, see health testing before breeding.

• Litter sizes are often small to moderate
• Visible weight gain may appear later than expected
• Heat sensitivity can increase in later pregnancy
• Delivery planning benefits from early discussion

Shih Tzu Pregnancy: Week-by-Week Expectations

Weeks 1-3: Establishing a Baseline

During the first few weeks, most Shih Tzus appear unchanged. Appetite, activity level, and demeanor typically remain consistent. Minor daily weight fluctuations are common and not meaningful on their own.

This phase is best used to establish reliable baseline data rather than searching for confirmation of pregnancy. Consistent weighing, timestamps, and brief notes create a reference point that becomes valuable later when physical changes begin to emerge.

Weeks 4-5: Early Mid-Pregnancy Changes

Around mid-pregnancy, subtle shifts may occur. Some Shih Tzus show mild appetite changes, short periods of fatigue, or slight rounding through the abdomen. These signs are often inconsistent and may come and go.

Weight gain during this stage may still be modest. Slow, steady increases are common and not inherently concerning. Trends observed over multiple measurements provide more insight than individual data points.

Weeks 6-7: Clearer Progression

Physical changes often become more noticeable during later mid-pregnancy. Abdominal expansion may be easier to observe, and movement comfort can shift. As weight increases, monitoring breathing effort and heat tolerance becomes more important.

Many breeders increase observation frequency during this phase — not to react to every change, but to ensure progression remains gradual and manageable. Sudden spikes in weight or visible discomfort warrant closer attention.

Weeks 8-9: Late Pregnancy and Readiness

Late pregnancy focuses less on growth and more on readiness. Appetite fluctuations, increased rest, and nesting behaviors may appear. Breathing comfort and temperature management deserve particular attention as delivery approaches.

Accurate, timestamped records are especially valuable at this stage. They support clearer discussions with veterinary professionals and reduce uncertainty during a period when decisions may need to be made efficiently.

Delivery Considerations in Shih Tzus

Many Shih Tzus deliver naturally, but delivery outcomes vary based on individual anatomy, litter size, and maternal condition. As a small breed with a brachycephalic head shape, some females may experience prolonged labor or fatigue during delivery.

Cesarean delivery is not uncommon and may be planned or decided based on observed progression rather than emergency circumstances alone. For more on what to expect, see our C-sections in dogs guide. Early discussion with a veterinarian allows breeders to prepare appropriately and reduces last-minute decision pressure.

Situations that warrant closer monitoring include stalled labor, prolonged straining without progress, visible distress, or declining maternal comfort. Clear records of timing, behavior, and progression support better-informed decisions.

Understanding Weight Gain During Shih Tzu Pregnancy

There is no single correct amount of weight a pregnant Shih Tzu should gain. Starting body condition, litter size, metabolism, and activity level all influence pregnancy weight trends.

Gradual gain is generally easier on movement and breathing than rapid increases late in pregnancy. Sudden spikes may indicate fluid retention or overfeeding, while unexpected drops can coincide with appetite changes or stress.

Weight data is most useful when interpreted alongside observation. Breathing comfort, heat tolerance, and willingness to move provide essential context that numbers alone cannot.

Newborn Shih Tzu Puppy Weight Tracking

Early puppy growth is one of the most critical monitoring periods for Shih Tzu litters. Puppies are small, energy reserves are limited, and even short disruptions in nursing can have noticeable effects.

Birth weights vary widely. Rather than focusing on size at birth, breeders benefit from watching each puppy's response in the first days — strong latch, consistent nursing, and steady upward trends are more informative than a single measurement.

Many breeders weigh puppies at least once daily, increasing frequency during the first seventy-two hours or when monitoring weaker puppies. Brief plateaus may occur, but sustained decline is a signal to intervene or seek professional input.

Recording notes alongside weights — such as supplementation, nursing difficulty, or milestone events — creates a clearer picture over time. These records are especially valuable during busy, sleep-deprived whelping periods.

For detailed guidance on caring for newborns, see how to care for newborn puppies. If a puppy shows signs of declining health, our fading puppy syndrome guide covers warning signs and interventions.

Shih Tzu Growth Expectations

Shih Tzu puppies grow steadily through their first year, with the most rapid changes occurring during the first six months. Males tend to run slightly heavier than females, but individual variation is significant.

These are approximate ranges. Always track your individual puppies rather than comparing to population averages.

Health Issues Relevant to Breeding

Shih Tzus carry several breed-specific health concerns that responsible breeders should understand and screen for before making breeding decisions.

• Renal dysplasia — Abnormal kidney development; a significant breed concern. DNA testing available for some lineages
• Brachycephalic obstructive airway syndrome (BOAS) — Usually mild to moderate in Shih Tzus compared to French Bulldogs, but still affects breeding decisions
• Eye problems — Proptosis (eye displacement due to shallow orbits), cataracts, dry eye (keratoconjunctivitis sicca), and corneal ulcers are all elevated in the breed
• Patellar luxation — Common in small breeds; graded I-IV severity
• Dental disease — Small jaw and brachycephalic skull create crowding and accelerated tartar buildup
• Intervertebral disc disease (IVDD) — Occurs at moderate rates due to the breed's compact build

For a broader overview, see our Health Testing Before Breeding guide. Understanding fading puppy syndrome is also important for Shih Tzu breeders, as small neonates with limited reserves are at higher risk.

Required Health Testing

The American Shih Tzu Club and OFA recommend the following evaluations before breeding. These tests help identify conditions that may be passed to offspring or affect the dam's ability to carry and deliver safely.

Practical Record-Keeping for Shih Tzu Breeders

Pregnancy and early puppy care involve rapid changes and limited margins for error. Relying on memory alone is rarely sufficient. Accurate records reduce guesswork and support clearer decisions under pressure.

Useful records include timestamps, consistent weights, and brief notes on feeding changes, supplementation, or observed concerns. Records are most effective when they preserve history rather than overwrite it.

The Whelping Date Calculator helps estimate your preparation timeline, and the Whelping Supplies Checklist ensures nothing is missed before the due window. Tools like the Animal Weight Tracker support this process by keeping entries simple, maintaining historical context, and allowing breeders to focus on trends rather than predictions.

The Grooming Is Not Optional

A Shih Tzu with a neglected coat is in pain. Mats pull at the skin, trap moisture, and cause infections. If you can't commit to regular grooming — whether at home or professionally — this is not your breed. A short clip reduces work but doesn't eliminate it.

Eye Problems Are When, Not If

Most Shih Tzus will have some eye issue during their lifetime. Tear staining is cosmetic. Corneal ulcers, dry eye, and cataracts are medical. Budget for eye-related vet visits and catch problems early — a small ulcer treated promptly costs far less than an advanced one.

They're Lovely Dogs for the Right Owner

Shih Tzus don't get the social media hype of Frenchies or the working-dog cachet of shepherds. They're just consistently pleasant, friendly, low-drama dogs that make excellent companions. For the person who wants a calm, affectionate small dog and is willing to manage grooming and eye care, few breeds are better.

Common Reasons Shih Tzus End Up in Rescue

• Grooming became overwhelming or too expensive
• Eye care costs exceeded expectations
• Owner health or lifestyle change
• House training struggles

Popularity

The Shih Tzu consistently ranks in the AKC's top 20 breeds. Popularity has been stable for decades, supported by their adaptability and pleasant temperament.

Price Ranges

From a responsible breeder with health clearances: $1,200-$2,500. Show-quality: $2,500-$4,000+. Shih Tzus from breeders who test for eye, joint, and kidney conditions are worth the investment.

Rescue Rates

Shih Tzu rescues report moderate intake. Most surrendered dogs need grooming rehabilitation (severely matted coats). Once groomed and assessed, they typically adopt quickly due to their friendly temperament.

Lifespan Trends

Average lifespan of 10-18 years, with most falling in the 12-16 range. One of the longer-lived breeds. Quality of life is generally good with appropriate eye care, grooming, and weight management.
