Mixed Shih Tzu Guide: Traits, Health, and Care for Popular Crossbreeds
Complete guide to mixed Shih Tzu designer dogs covering temperament, size, health risks, grooming needs, and costs for popular Shih Tzu crosses.
What Is a Mixed Shih Tzu?
A mixed Shih Tzu is any crossbreed that pairs the Shih Tzu with another breed, producing what the designer dog market calls a "hybrid" or "designer mix." Unlike purebred dogs governed by AKC breed standards, mixed Shih Tzu dogs have no single governing standard — which means every litter, and sometimes every puppy within a litter, can look and behave differently.
The Shih Tzu's popularity as a crossbreed parent stems from its compact size (9–16 lb / 4–7 kg), affectionate disposition, and relatively low exercise needs. Breeders pair it with other small or toy breeds to produce companion dogs that retain the Shih Tzu's lap-dog charm while potentially altering coat type, energy level, or facial structure.
The most common mixed Shih Tzu crosses you'll encounter include:
- Shih-Poo (Shih Tzu × Poodle, usually Toy or Miniature)
- Shorkie (Shih Tzu × Yorkshire Terrier)
- Mal-Shih (Shih Tzu × Maltese)
- Shih Tzu × Chihuahua (sometimes called a ShiChi)
- Shih Tzu × Bichon Frisé (Shichon or Zuchon)
- Shih Tzu × Pekingese (Peke-a-Tzu)
This guide covers what you can reasonably expect — and what you can't — when bringing home a mixed Shih Tzu.
The Parent Breeds: Shih Tzu and Common Cross Partners
Understanding any mixed Shih Tzu starts with understanding both parent breeds. Here's how the Shih Tzu compares to the breeds it's most frequently crossed with:
| Trait | Shih Tzu | Toy/Mini Poodle | Yorkshire Terrier | Maltese | Chihuahua |
|---|---|---|---|---|---|
| Weight | 9–16 lb (4–7 kg) | Toy: 4–6 lb (2–3 kg); Mini: 10–15 lb (5–7 kg) | 4–7 lb (2–3 kg) | Under 7 lb (3 kg) | 2–6 lb (1–3 kg) |
| Height | 9–10.5 in (23–27 cm) | Toy: 10 in; Mini: 10–15 in (25–38 cm) | 7–8 in (18–20 cm) | 7–9 in (18–23 cm) | 5–8 in (13–20 cm) |
| Coat Type | Long, double coat, hair-like | Curly, single coat, hair-like | Long, straight, silky, single coat | Long, straight, silky, single coat | Short or long, double or single |
| Shedding | Low | Very low | Very low | Very low | Low to moderate |
| Muzzle Shape | Brachycephalic (short) | Mesocephalic (moderate) | Small but not flat | Small, slightly tapered | Apple or deer head, variable |
| Energy Level | Low to moderate | Moderate to high | Moderate | Low to moderate | Moderate (burst energy) |
| Lifespan | 10–18 years | 10–18 years | 11–15 years | 12–15 years | 14–16 years |
| AKC Group | Toy | Toy / Non-Sporting | Toy | Toy | Toy |
The Shih Tzu's brachycephalic (flat-faced) anatomy is the single most consequential trait it passes to offspring. A mixed Shih Tzu that inherits a shortened muzzle faces the same respiratory risks as a purebred Shih Tzu — including brachycephalic obstructive airway syndrome (BOAS). A mix that inherits the longer muzzle of a Poodle or Yorkie parent may breathe more easily but lose the distinctive "chrysanthemum face" look.
Generations Explained: F1, F1B, F2, and Multigen
Understanding Generation Labels
- F1 (First Generation): One purebred Shih Tzu × one purebred other breed (e.g., a purebred Poodle). Puppies are 50% Shih Tzu and 50% the other breed. Trait expression is the most unpredictable at this generation.
- F1B (First Generation Backcross): An F1 mixed Shih Tzu bred back to one of the parent breeds — usually the Poodle, to increase the likelihood of a curly, low-shedding coat. Puppies are 75% one breed and 25% the other.
- F2 (Second Generation): Two F1 mixed Shih Tzus bred together. Puppies are still 50/50 genetically, but trait expression becomes more variable because recessive genes from both sides can surface unpredictably.
- F2B, F3, Multigen: Successive generations of mixed-to-mixed breedings. Some breeders market these as more "predictable," but without a closed stud book and a breed standard, variation persists across every generation.
Why does this matter? Because an F1 Shih-Poo might have a straight, silky Shih Tzu coat in one puppy and a tight Poodle curl in its littermate. An F1B Shih-Poo bred back to a Poodle will more consistently produce curly coats — but you're also increasing the proportion of Poodle traits like higher energy and a longer muzzle. Always ask a breeder which generation they're producing and request to see both parent dogs in person.
Size, Coat, and Physical Traits: What to Expect
Because mixed Shih Tzu crosses involve small and toy breeds, the size range is relatively narrow — but individual variation within that range is significant.
| Mixed Shih Tzu Cross | Weight Range | Height Range | Notes |
|---|---|---|---|
| Shih-Poo (Toy Poodle cross) | 6–14 lb (3–6 kg) | 8–13 in (20–33 cm) | Mini Poodle crosses trend larger: up to 18 lb (8 kg) |
| Shorkie | 6–12 lb (3–5 kg) | 6–10 in (15–25 cm) | Often smaller than purebred Shih Tzu |
| Mal-Shih | 6–12 lb (3–5 kg) | 8–12 in (20–30 cm) | Very similar size to both parents |
| ShiChi | 5–12 lb (2–5 kg) | 6–10 in (15–25 cm) | Chihuahua parent pulls size down |
| Shichon (Bichon cross) | 9–16 lb (4–7 kg) | 9–12 in (23–30 cm) | Bichon adds slight bulk |
Coat Type Possibilities
Coat inheritance is one of the most variable traits in any mixed Shih Tzu. Here's what's possible depending on the cross:
- Straight, long, silky: Inherited from the Shih Tzu or Yorkie parent. Requires daily brushing to prevent matting. Low shedding but high grooming maintenance.
- Curly or wavy: Inherited from the Poodle or Bichon parent. Tighter curls shed less but mat faster. Wavy coats are the most common "middle ground" in F1 Shih-Poos.
- Short, smooth: Possible when the Shih Tzu is crossed with a smooth-coat Chihuahua. Lowest grooming requirement but moderate shedding and less cold-weather protection.
- Double coat: The Shih Tzu carries a double coat (dense undercoat beneath a longer topcoat). If the puppy inherits this from the Shih Tzu side, expect seasonal "blowing" of the undercoat in spring and fall, even if the other parent is single-coated.
Is a mixed Shih Tzu hypoallergenic? No dog is truly hypoallergenic — allergies are triggered by dander and saliva proteins, not fur length. However, mixed Shih Tzu crosses that inherit hair-like coats (from Poodle, Maltese, or Yorkie parents) rather than fur coats tend to shed less dander into the environment. An F1B Shih-Poo with a tight Poodle curl is the closest you'll get to "low-allergen," but individual allergic reactions vary. Spend at least 30 minutes with the specific puppy before committing.
Temperament: Best-Case and Challenging Scenarios
Temperament in mixed Shih Tzu dogs ranges widely depending on which parent's behavioral tendencies dominate — and on early socialization during the critical 3-to-14-week window.
| Trait | Best-Case Scenario | Challenging Scenario | What Influences It |
|---|---|---|---|
| Friendliness | Outgoing, greets strangers warmly, good with children over age 6 | Reserved, aloof with strangers, may snap if startled | Chihuahua and Yorkie parents can contribute wariness; early socialization is critical |
| Trainability | Eager to please, responds well to food rewards, learns basic cues in 2–4 weeks | Stubborn, easily distracted, slow to house-train (6–12 months) | Shih Tzu independence + toy-breed bladder capacity = patience required |
| Barking | Alert barking at doorbell, settles quickly | Frequent barking at passersby, other dogs, and noises; difficult to quiet | Yorkie and Chihuahua parents contribute strong vocal tendencies |
| Separation Tolerance | Comfortable alone for 3–4 hours with enrichment toys | Severe separation anxiety: destructive behavior, howling within 30 minutes of owner departure | Shih Tzus were bred as companion dogs and bond intensely; Poodle crosses may amplify this |
| Dog-to-Dog Social | Plays well at dog park, appropriate greetings | Leash reactivity, fear-based aggression toward larger dogs | Small size triggers defensive behavior if not socialized early; Yorkie crosses may be scrappier |
The most reliable predictor of a mixed Shih Tzu puppy's temperament is observing both parent dogs. If the Shih Tzu parent is calm and friendly and the other parent is relaxed and handler-focused, odds are good the puppies will land somewhere in that range. If either parent shows fear-based reactivity, resource guarding, or excessive vocalization, expect those traits to appear in at least some puppies.
For training, use only positive reinforcement and force-free methods. Toy and small breeds are particularly sensitive to aversive techniques — prong collars, shock collars, and alpha rolls can cause both physical injury to a small trachea and lasting behavioral damage. Reward-based training with high-value treats (small pieces of boiled chicken or commercial training treats under 3 calories each) works reliably for this size class.
Health Considerations: Inherited Risks from Both Parents
Let's address the hybrid vigor myth directly: crossing two purebreds does not guarantee healthier puppies. Hybrid vigor (heterosis) applies primarily when you cross two genetically diverse populations with low inbreeding coefficients. Many designer breeders use Shih Tzus and Poodles that come from the same limited gene pools as purebred show lines. If both parents carry the same recessive disease gene — such as the gene for progressive retinal atrophy (PRA) — the puppies are at the same risk as purebreds.
Here are the health conditions a mixed Shih Tzu may inherit, organized by parent breed:
| Condition | Inherited From | Prevalence / Risk | Screening Available |
|---|---|---|---|
| Brachycephalic Obstructive Airway Syndrome (BOAS) | Shih Tzu | High in flat-faced offspring; estimated 50%+ of brachycephalic dogs show clinical signs | Physical exam; BOAS functional grading by vet |
| Hip Dysplasia | Shih Tzu, Poodle | Orthopedic Foundation for Animals (OFA) reports ~10–13% of Shih Tzus affected | OFA/PennHIP radiographic screening of parents |
| Patellar Luxation | All small/toy breeds | Very common in toy breeds; estimated 5–20% prevalence depending on cross | OFA patella evaluation of parents |
| Progressive Retinal Atrophy (PRA) | Shih Tzu, Poodle | Recessive gene; both parents must be carriers for puppies to be affected | DNA test available (Optigen prcd-PRA test) |
| Dental Disease | All small breeds | Extremely high prevalence; 80%+ of toy breeds show periodontal disease by age 3 | Regular veterinary dental exams; daily tooth brushing |
| Intervertebral Disc Disease (IVDD) | Shih Tzu (chondrodystrophic breed) | Moderate risk; Shih Tzus have a genetic predisposition to early disc degeneration | No preventive screening; manage weight, avoid high-impact jumping |
| Portosystemic Shunt (Liver Shunt) | Yorkshire Terrier, Maltese | Low overall but significantly elevated in Yorkie and Maltese lines | Bile acids test; abdominal ultrasound |
| Collapsed Trachea | Shih Tzu, Yorkie, Chihuahua, Poodle | Common in all toy breeds; worsens with obesity and collar pressure | Radiographs or fluoroscopy; use harness instead of collar |
When to see the vet immediately: If your mixed Shih Tzu shows labored breathing (noisy breathing at rest, blue-tinged gums, exercise intolerance in cool weather), sudden hind-limb weakness or paralysis, seizures, or persistent vomiting, seek emergency veterinary care. Brachycephalic dogs can deteriorate rapidly in heat — never leave a flat-faced mix in a car or outdoors when temperatures exceed 75°F (24°C).
Responsible breeders of mixed Shih Tzu dogs should provide health clearances for both parent dogs — not just one. Ask for OFA or PennHIP hip scores, OFA patella evaluations, and breed-specific DNA test results. A breeder who cannot produce documentation for both parents is not conducting health screening. The AVMA recommends obtaining puppies from breeders who perform and share health testing results.
Grooming, Exercise, and Daily Care
Grooming by Coat Type
Your mixed Shih Tzu's grooming schedule depends entirely on which coat it inherits:
- Long, straight coat (Shih Tzu / Yorkie / Maltese dominant): Daily brushing with a slicker brush and metal comb. Professional grooming every 4–6 weeks. Expect to spend $50–$90 per grooming session depending on your region. Eye area requires daily wiping with a damp cloth to prevent tear staining — brachycephalic and flat-faced mixes are prone to epiphora (overflow tearing).
- Curly or wavy coat (Poodle / Bichon dominant): Brushing every 2–3 days minimum. Professional grooming every 6–8 weeks. Curly coats mat at the skin level where you can't see it — always comb through to the skin after brushing. Budget $60–$100 per session for a full clip and bath.
- Short coat (smooth Chihuahua dominant): Weekly brushing with a rubber grooming mitt. Bathing every 6–8 weeks. Minimal professional grooming needed. This is the lowest-maintenance coat option but the least common in Shih Tzu crosses.
Regardless of coat type, plan for:
- Nail trims every 2–3 weeks (small dogs' nails grow proportionally faster relative to their activity level)
- Daily tooth brushing with an enzymatic dog toothpaste — toy breeds are the highest-risk group for early periodontal disease
- Ear cleaning weekly if the dog has drop ears (Shih Tzu, Poodle, and Bichon all contribute drop ears)
Exercise Requirements
Most mixed Shih Tzu dogs need 30–45 minutes of daily activity, split across two or three short walks. Brachycephalic mixes should not be exercised in heat or humidity — opt for early morning and evening walks in summer, and indoor play sessions during extreme weather.
A Shih-Poo with a Poodle-dominant energy profile may need closer to 45–60 minutes including puzzle toys and training games. A Mal-Shih or Shorkie with stronger Shih Tzu traits may be fully satisfied with 20–30 minutes of gentle walking plus indoor sniffing and lap time.
Cost: What You'll Pay for a Mixed Shih Tzu
| Cost Category | Low End | Mid Range | High End |
|---|---|---|---|
| Purchase price (from breeder) | $500–$800 | $1,000–$2,000 | $2,500–$4,000+ |
| Adoption/rescue fee | $150–$300 | $300–$500 | N/A |
| First-year veterinary care (vaccines, spay/neuter, wellness) | $600 | $900 | $1,500 |
| Annual grooming (professional) | $400 | $650 | $1,200 |
| Annual food cost (quality small-breed kibble or wet food) | $200 | $350 | $600 |
| Pet insurance (monthly premium, accident + illness) | $25/mo | $40/mo | $60/mo |
The wide purchase price range reflects breeder practices. Low-end prices ($500–$800) typically come from backyard breeders or puppy brokers who do not health-test parent dogs. Mid-range ($1,000–$2,000) is typical for small-scale hobby breeders who perform some health screening. High-end prices ($2,500+) come from established designer-dog breeders who provide full OFA/DNA clearances, early neurological stimulation (ENS) protocols, and take-back guarantees.
Rescue availability for mixed Shih Tzu dogs is moderate. Shih Tzu-specific rescues (such as the American Shih Tzu Club's rescue network) occasionally take in mixes. General small-breed rescues and municipal shelters in urban areas regularly have Shih Tzu crosses. Adult dogs from rescues cost significantly less and often come already spayed/neutered, vaccinated, and microchipped — though you sacrifice the ability to screen parent dogs for health and temperament.
Who Is a Mixed Shih Tzu Best Suited For?
A mixed Shih Tzu is a strong fit for:
- Apartment dwellers: Their small size and moderate exercise needs make them ideal for apartments and condos. Check your building's weight restrictions — most mixed Shih Tzus fall well under 20 lb (9 kg) limits.
- Older adults or retirees: The companion-dog temperament and low exercise demands suit less active households. Be aware that toy breeds require someone home for most of the day — they are not suited to 10-hour alone periods.
- Families with older children (age 8+): Mixed Shih Tzus are generally gentle and playful, but their small size makes them fragile. Toddlers and young children can accidentally injure a 8 lb (3.5 kg) dog by dropping or squeezing them.
- First-time dog owners: The manageable size and generally cooperative temperament make these crosses reasonable first dogs, provided the owner commits to positive reinforcement training and daily grooming.
A mixed Shih Tzu is not ideal for:
- Households wanting an off-leash hiking companion (these are not endurance athletes)
- Families with very young children who cannot yet handle small animals gently
- Owners unwilling to budget for professional grooming every 4–8 weeks
- Anyone seeking a predictable, guaranteed temperament — variability is inherent to any crossbreed
Frequently Asked Questions
What two breeds make up a mixed Shih Tzu?
A mixed Shih Tzu always includes one Shih Tzu parent crossed with another breed. The most common pairings are with Toy or Miniature Poodles (Shih-Poo), Yorkshire Terriers (Shorkie), Maltese (Mal-Shih), Chihuahuas (ShiChi), and Bichon Frisés (Shichon). The specific cross determines the puppy's likely size, coat, and temperament tendencies.
How big will a mixed Shih Tzu get?
Most mixed Shih Tzu dogs reach 6–16 lb (3–7 kg) and stand 6–13 inches (15–33 cm) at the shoulder. The exact size depends on the other parent breed's size and which parent's growth genes dominate. Miniature Poodle crosses trend toward the larger end of this range, while Chihuahua and Yorkie crosses trend smaller. You won't know a puppy's final adult weight with certainty until around 10–12 months of age.
What will the temperament be like?
Expect an affectionate, people-oriented companion dog that bonds closely with its owner. Energy level varies from low (Shih Tzu / Maltese dominant) to moderate (Poodle dominant). Barking tendency ranges from occasional to frequent depending on whether Yorkie or Chihuahua vocal traits emerge. Early socialization between 3 and 14 weeks is the single biggest factor you can control — enroll in a force-free puppy class and expose the puppy to diverse people, surfaces, and sounds during this critical window.
Is a mixed Shih Tzu hypoallergenic or low-shedding?
No dog is truly hypoallergenic. However, mixed Shih Tzus that inherit hair-like coats from Poodle, Maltese, or Yorkie parents tend to shed minimally and may be better tolerated by people with mild dog allergies. Crosses with smooth-coat Chihuahua parents may shed more. If allergies are a concern, spend time with the specific puppy before purchasing and consult your allergist.
What health issues might a mixed Shih Tzu inherit?
Key health risks include BOAS (if the puppy inherits a flat face), patellar luxation, hip dysplasia, progressive retinal atrophy, collapsed trachea, dental disease, and IVDD. The Merck Veterinary Manual notes that small and toy breeds carry elevated risk for dental and tracheal conditions regardless of crossbreeding. Always consult your veterinarian to establish a preventive care plan tailored to your dog's specific anatomy and lineage.
How much does a mixed Shih Tzu cost?
Purchase prices range from $500 at the low end (backyard breeders, no health testing) to $4,000+ from established designer breeders with full health clearances. Adoption fees range from $150–$500. First-year total ownership costs (purchase price + vet care + grooming + food + supplies) typically fall between $2,000 and $4,500. Annual ongoing costs after the first year average $1,200–$2,500 depending on grooming frequency and veterinary needs.
Can I find a mixed Shih Tzu in a rescue?
Yes. Shih Tzu crosses appear regularly in small-breed rescues and municipal shelters, particularly in urban areas. Adult dogs (2–8 years old) are the most commonly available. Adopting an adult gives you the advantage of already knowing the dog's full-grown size, coat type, and established temperament — removing much of the unpredictability of buying a puppy.
