How Long Do Shih Tzus Live? Lifespan, Health & Care Guide

Shih Tzu Lifespan: What to Expect From Your Little Lion Dog

If you've ever found yourself wondering how long do Shih Tzus live, you're not alone — it's one of the most searched questions about this beloved toy breed. The short answer: Shih Tzus typically live between 10 and 18 years, with a median lifespan of around 13 to 14 years. That places them among the longer-lived dog breeds, especially within the toy group.

But lifespan is only part of the story. A Shih Tzu's longevity depends heavily on genetics, preventive veterinary care, weight management, and how well you manage the breed-specific health risks they carry. In this guide, we'll walk through everything that shapes a Shih Tzu's life — from puppyhood through their senior years — so you can give your dog the longest, healthiest life possible.

Breed Overview: The Shih Tzu at a Glance

The Shih Tzu (pronounced "SHEED-zoo") originated in 17th-century China, where they were bred as companion dogs for Chinese royalty during the Ming Dynasty. The breed was developed by crossing the Lhasa Apso with early Pekingese-type dogs, resulting in the distinctive "little lion" appearance — "Shih Tzu" literally translates to "lion dog" in Mandarin.

After the Chinese Communist Revolution nearly wiped out the breed, a small number of Shih Tzus were exported to England and Scandinavia in the 1930s, then to the United States in the 1950s. The American Kennel Club recognized the Shih Tzu in 1969, and they've remained one of the most popular toy breeds in the U.S. ever since, consistently ranking in the top 20 AKC registrations.

Temperament & Personality: What Living With a Shih Tzu Is Really Like

Shih Tzus were bred for one purpose: companionship. Unlike working breeds that need a job, your Shih Tzu's job is you. This shapes their entire personality.

Affectionate lap dwellers. Expect your Shih Tzu to follow you from room to room and settle onto your lap the moment you sit down. They're not clingy in the anxious sense — they're simply bred to be near their people. In multi-dog households, a Shih Tzu will typically position itself closest to whichever human is sitting still.

Outgoing with strangers. Where some toy breeds are suspicious of newcomers, Shih Tzus tend to greet visitors with a wagging tail and a wiggle. They're poor watchdogs — they're more likely to show an intruder where the treats are kept than to bark an alarm.

Playful but not hyperactive. A Shih Tzu will enthusiastically chase a soft toy down a hallway, then immediately curl up for a nap. Play sessions are typically 5–10 minutes before they self-regulate and move on. This makes them ideal for households where high-energy dogs would be overwhelming.

Stubborn streak during training. Shih Tzus are intelligent but not biddable in the way a Border Collie is. They understand commands quickly but may decide compliance isn't worth the effort, especially if there's no immediate reward. This isn't a lack of intelligence — it's an independent temperament. Positive reinforcement with high-value treats (small pieces of boiled chicken or freeze-dried liver) works far better than repeated commands.

Gentle with children (with supervision). Shih Tzus generally tolerate gentle handling from children, but their small size and prominent eyes make them vulnerable to accidental injury. They're best suited to families with children aged 6 and older who understand how to handle a small dog respectfully.

Physical Characteristics & Size: How Big Does a Shih Tzu Get?

Adult Shih Tzus stand 9 to 10.5 inches (23–27 cm) at the withers and weigh between 9 and 16 pounds (4–7.3 kg). Males and females are similar in size, though males tend toward the heavier end of the range. The AKC breed standard specifies that a Shih Tzu should never weigh less than 9 pounds or more than 16 pounds.

Their most distinctive physical feature is their brachycephalic (flat-faced) skull structure. This gives them the characteristic short muzzle, large round dark eyes, and undershot bite (lower jaw extends slightly beyond the upper jaw). Their ears are large, pendant, and heavily feathered. The tail is heavily plumed and carried curled over the back.

The coat is a long, luxurious double coat that can be any color or color combination. Common colors include gold and white, black and white, liver, brindle, and solid black. A white blaze on the forehead and a white tail tip are considered desirable in the show ring. Many pet owners opt for a "puppy cut" (1–2 inch trimmed coat) to reduce maintenance.

Factors That Affect How Long Shih Tzus Live

Several key factors determine whether your Shih Tzu lives to 10 or 18. Understanding these lets you make informed decisions throughout their life.

Genetics and responsible breeding. Shih Tzus from breeders who perform OFA (Orthopedic Foundation for Animals) health clearances on parent dogs — including cardiac evaluations, patella evaluations, and ophthalmologist reports — tend to have fewer inherited conditions. Reputable breeders will share these test results openly. If a breeder can't provide health clearances, that's a significant red flag.

Brachycephalic airway management. As a flat-faced breed, Shih Tzus are predisposed to brachycephalic obstructive airway syndrome (BOAS). Dogs with more moderate facial structure (slightly longer muzzles) tend to breathe easier and live longer. Avoiding heat exposure, using a harness instead of a collar, and maintaining a lean body weight all reduce airway stress.

Dental care. Small breeds like the Shih Tzu are exceptionally prone to periodontal disease — an estimated 80% of toy breed dogs show signs of dental disease by age 3. Bacteria from gum infections can enter the bloodstream and damage the heart, liver, and kidneys, directly shortening lifespan. Daily tooth brushing with enzymatic dog toothpaste and annual veterinary dental cleanings under anesthesia are non-negotiable for longevity.

Preventive veterinary care. Twice-yearly wellness exams (annual for adults, biannual for seniors over age 8) catch problems early. Senior bloodwork panels starting at age 7 can detect kidney changes, thyroid issues, and liver abnormalities before symptoms appear — when treatment is most effective and least costly.

Spay/neuter status. Studies published in veterinary journals suggest that spayed and neutered dogs tend to live 1–2 years longer on average than intact dogs, partly due to reduced cancer risk (mammary, testicular, uterine) and partly due to reduced roaming and trauma risk. Discuss timing with your veterinarian — current research for small breeds suggests waiting until after physical maturity (around 12 months) may offer joint health benefits.

Common Health Problems Shih Tzus Are Prone To

While Shih Tzus are generally a healthy toy breed, they carry predispositions to several conditions. Knowing what to watch for helps you catch problems early and discuss preventive strategies with your veterinarian.

Intervertebral Disc Disease (IVDD) deserves special attention. Shih Tzus are a chondrodystrophic breed, meaning their spinal discs can calcify prematurely, making them prone to disc herniation. Symptoms include sudden back pain, reluctance to jump, a hunched posture, dragging rear legs, or sudden paralysis. This is a veterinary emergency. If your Shih Tzu shows any of these signs, seek immediate veterinary care. Early surgical intervention (within 24–48 hours of paralysis onset) has an 80–90% success rate for restoring mobility.

Eye conditions are another major concern. Their prominent, large eyes are vulnerable to corneal ulcers (from scratches or rubbing), proptosis (eye displacement from trauma), and progressive retinal atrophy (PRA). Keep hair trimmed around the eyes, avoid letting your Shih Tzu hang their head out of car windows, and seek veterinary attention for any eye redness, squinting, or discharge.

Exercise, Grooming & Daily Care Requirements

Despite their small size, Shih Tzus have specific daily care needs that directly impact their health and lifespan.

Exercise Needs: 20–30 Minutes Per Day

Shih Tzus need approximately 20 to 30 minutes of exercise daily, ideally split into two walks of 10–15 minutes each. They're not built for jogging, hiking, or sustained aerobic activity — their brachycephalic airway means they overheat and tire quickly.

Recommended activities include:

• Leash walks at a moderate pace on cool mornings or evenings (avoid midday heat above 80°F / 27°C)
• Indoor play sessions — short 5-minute games of fetch with soft toys down a hallway
• Sniffing enrichment — scatter kibble in a snuffle mat or let them explore a safe yard at their own pace
• Puzzle feeders — Kong toys or Outward Hound puzzle games to engage their mind without physical strain

Always use a harness rather than a collar for walks. Collars put pressure on the trachea, which is already compromised in brachycephalic breeds. A front-clip harness (such as the Ruffwear Front Range or the 2 Hounds Design Freedom Harness) gives you control without airway pressure.

Grooming: High Maintenance, Non-Negotiable

The most commonly neglected grooming task is eye cleaning. Shih Tzus have shallow eye sockets and prominent eyes, which leads to tear staining and mucus accumulation in the inner eye corners. Daily wiping with a sterile, fragrance-free eye wipe prevents crusting, reduces infection risk, and keeps your dog comfortable. If you notice persistent redness, green discharge, or your dog pawing at their eyes, schedule a veterinary exam — corneal ulcers are common in this breed and require prompt treatment.

Training & Intelligence

Shih Tzus rate around moderate for trainability. They learn commands readily but aren't naturally inclined to obey for the sake of obeying. This breed responds best to:

• Short training sessions — 3 to 5 minutes, 2–3 times daily
• High-value food rewards — tiny pieces of real chicken, cheese, or commercial training treats (keep portions small to avoid weight gain)
• Positive reinforcement only — reward-based methods, clicker training, and lure-and-reward techniques
• Patience with housebreaking — Shih Tzus are notoriously slow to house-train, often taking 4–6 months for reliable indoor habits. Consistent crate training and scheduled potty breaks every 1–2 hours during puppyhood are essential

Never use aversive methods like shock collars, prong collars, or alpha rolls. These damage the trust-based bond Shih Tzus need and can trigger fear-based behaviors. If you're struggling with training, work with a certified professional dog trainer (CPDT-KA) who uses force-free methods.

Family Suitability: Kids, Pets & Apartment Living

With children: Shih Tzus do well with respectful children aged 6 and up. Their small size and fragile eye structure mean toddlers and very young children can accidentally injure them through rough handling. Always supervise interactions and teach children to approach the dog calmly, avoid grabbing the face, and never pick up the dog without adult help.

With other pets: Shih Tzus generally coexist peacefully with other dogs and even cats, especially when socialized from puppyhood. They're not territorial or aggressive. That said, their small size makes them vulnerable to accidental injury from large, exuberant dogs — supervise play with dogs over 30 pounds.

Apartment living: The Shih Tzu is one of the best apartment breeds available. Their compact size, low exercise needs, and relatively quiet nature (they bark less than many toy breeds) make them ideal for apartments, condos, and senior living communities. They don't need a yard — a daily walk and indoor play are sufficient.

Cost of Ownership: Buying and Maintaining a Shih Tzu

Budgeting accurately for a Shih Tzu helps avoid unpleasant surprises. Here's what to expect:

Puppy purchase price:

• From a responsible AKC-registered breeder with health clearances: $1,500–$3,500
• Show-quality puppies from champion lines: $3,500–$6,000+
• Adoption from a breed-specific rescue (e.g., American Shih Tzu Club Rescue): $300–$600

First-year costs (estimated):

• Puppy vaccination series (DHPP, rabies, bordetella): $200–$400
• Spay/neuter surgery: $400–$800
• Initial supplies (crate, harness, bowls, grooming tools, bed): $300–$600
• Professional grooming (8–10 sessions): $400–$900
• High-quality small-breed food (e.g., Royal Canin Shih Tzu, Hill's Science Diet Small Paws): $250–$400/year
• Pet insurance (recommended): $300–$600/year
• Total first-year estimate: $2,500–$5,000+ (including puppy purchase)

Ongoing annual costs (years 2+):

• Veterinary care (2 wellness exams, vaccines, heartworm/flea prevention): $400–$800
• Grooming (10–12 sessions): $500–$1,080
• Food: $250–$400
• Dental cleaning (annual, starting around age 2–3): $500–$1,500
• Pet insurance: $300–$600
• Total annual estimate: $1,950–$4,380

Over a 14-year median lifespan, total lifetime cost of a Shih Tzu (excluding the purchase price) typically ranges from $25,000 to $55,000, depending on health issues and grooming frequency. Pet insurance with a comprehensive accident-and-illness plan can help manage unexpected veterinary costs, particularly for IVDD surgery or BOAS correction.

Frequently Asked Questions About Shih Tzu Lifespan

Is the Shih Tzu a good breed for first-time dog owners?

Yes. The Shih Tzu is one of the most forgiving breeds for new owners. Their low exercise needs, adaptable temperament, and small size make them manageable even in small living spaces. The main challenges for first-timers are the grooming commitment and housebreaking patience required. If you're prepared for daily brushing and a longer potty-training timeline, a Shih Tzu is an excellent first dog.

How can I help my Shih Tzu live longer?

Five evidence-based steps make the biggest difference: (1) Maintain a lean body weight — keep your Shih Tzu at the lower end of their healthy range (9–12 lb for most individuals). (2) Brush teeth daily and get annual veterinary dental cleanings. (3) Use a harness, never a collar, to protect the trachea. (4) Avoid heat exposure — never walk in temperatures above 80°F (27°C) and never leave in a car. (5) Schedule twice-yearly veterinary exams with senior bloodwork starting at age 7.

Do Shih Tzus have a lot of health problems?

Compared to many purebred dogs, Shih Tzus have a moderate number of breed-specific health concerns. Their brachycephalic anatomy creates lifelong airway and eye vulnerability, and dental disease is nearly universal without preventive care. However, they avoid the severe genetic conditions that plague some breeds (like the high cancer rates in Golden Retrievers or the heart disease in Cavalier King Charles Spaniels). With a responsible breeder and consistent preventive care, most Shih Tzus live long, relatively healthy lives.

Are Shih Tzus good with children and other pets?

Yes, with appropriate supervision. Shih Tzus are gentle and sociable with children aged 6+ who handle them carefully. They coexist well with other dogs and typically accept cats without issue. Avoid pairing them with very large, boisterous dogs that could accidentally injure them during play, and always teach children to respect the dog's space during eating and sleeping.

What's the oldest a Shih Tzu has ever lived?

The oldest documented Shih Tzu was Smokey, who lived to 23 years. While this is exceptional, it illustrates the breed's longevity potential when genetics, weight management, dental care, and preventive veterinary medicine all align. Many well-cared-for Shih Tzus reach 15–17 years.

Should I get pet insurance for my Shih Tzu?

Strongly recommended. Given the breed's predisposition to IVDD (surgery: $3,000–$8,000), BOAS (surgery: $500–$5,000), and chronic dental disease, pet insurance can pay for itself many times over. Look for plans that cover hereditary conditions, dental illness, and have no breed-specific exclusions. Companies like Trupanion, Healthy Paws, and Nationwide offer plans starting around $30–$50/month for a Shih Tzu puppy enrolled early.
