Shih Tzu Terrier Mix Dogs: Traits, Health, and Care Guide
Everything about Shih Tzu Terrier mix dogs: size, temperament, coat types, health risks, grooming needs, costs.
The Shih Tzu Terrier Mix: What You're Actually Getting
When you bring home a Shih Tzu Terrier mix, you're signing up for a genetic lottery. This designer cross pairs the ancient Chinese companion breed — the Shih Tzu — with one of several terrier breeds, most commonly the Yorkshire Terrier (producing the "Shorkie"), Jack Russell Terrier, or West Highland White Terrier. The result can be a delightful, spirited companion, but the variability between individual puppies is significant, even within the same litter.
Unlike purebred dogs governed by AKC breed standards, Shih Tzu Terrier mix dogs have no uniform blueprint. One puppy may inherit the Shih Tzu's brachycephalic (flat-faced) structure and silky coat, while a littermate gets the terrier parent's longer muzzle and wiry fur. Understanding this unpredictability is essential before committing to this cross.

Parent Breed Breakdown: Shih Tzu and Terrier Traits
To predict what a Shih Tzu Terrier mix might look and behave like, you need to understand both parent breeds. The Shih Tzu side is relatively consistent — a toy companion breed with centuries of selective breeding for lap-dog temperament. The terrier side introduces more variability because "terrier" encompasses dozens of breeds with different sizes, coats, and drive levels.
| Trait | Shih Tzu | Yorkshire Terrier (Most Common Terrier Parent) |
|---|---|---|
| Weight | 9–16 lb (4–7.3 kg) | 4–7 lb (1.8–3.2 kg) |
| Height | 8–11 inches | 7–8 inches |
| Coat | Long, flowing double coat; hair (not fur) | Long, silky single coat; hair-like texture |
| Temperament | Affectionate, outgoing, low prey drive | Bold, vocal, high prey drive |
| Trainability | Moderate — can be stubborn | Moderate — intelligent but independent |
| Barking | Low to moderate | High — alert barker |
| Prey Drive | Low | High — bred to chase rodents |
| AKC Group | Toy | Toy |
When the terrier parent is a Jack Russell Terrier instead of a Yorkie, expect a noticeably different mix: higher energy (Jack Russells need 60+ minutes of vigorous exercise daily), stronger prey drive, and potentially a larger adult size of 12–18 lb (5.4–8.2 kg). Always ask the breeder which specific terrier breed was used.
Understanding Generations: F1, F1B, F2, and Multigen
Not all Shih Tzu Terrier mix dogs are bred the same way. The generation classification tells you how predictable the puppies' traits will be and whether any "hybrid vigor" benefits are likely to apply.
- F1 (First Generation): One purebred Shih Tzu × one purebred Terrier. Maximum genetic diversity, but highest trait unpredictability. Puppies can look wildly different from each other.
- F1B (First Generation Backcross): An F1 Shih Tzu Terrier mix × one purebred parent (usually Shih Tzu to get a calmer temperament, or Terrier to get a smaller size). Slightly more predictable traits leaning toward the backcross parent.
- F2 (Second Generation): Two F1 Shih Tzu Terrier mixes bred together. High variability — recessive traits from both breeds can resurface unpredictably.
- Multigen (F3+): Multiple generations of Shih Tzu Terrier crosses bred together. Traits become more stabilized, but true multigen lines for this specific mix are rare since it's not as established as Labradoodles or Goldendoodles.
Most Shih Tzu Terrier mixes you'll encounter are F1 crosses. Responsible breeders should disclose the generation and provide health testing documentation for both parent dogs. If a breeder can't tell you which generation a litter is, that's a red flag.
Size, Coat, and Physical Traits: What to Expect
The most common question from prospective owners is: how big will this mixed breed get? The honest answer depends on which terrier breed is in the mix and which parent's genes dominate.
| Terrier Parent | Expected Adult Weight | Expected Adult Height | Coat Likelihood |
|---|---|---|---|
| Yorkshire Terrier (Shorkie) | 7–12 lb (3.2–5.4 kg) | 8–11 inches | Long, silky; low-shedding likely |
| Jack Russell Terrier | 10–16 lb (4.5–7.3 kg) | 10–14 inches | Short-to-medium, possibly wiry; moderate shedding |
| West Highland White Terrier | 12–18 lb (5.4–8.2 kg) | 10–12 inches | Medium, double coat; moderate shedding |
| Rat Terrier | 10–18 lb (4.5–8.2 kg) | 10–14 inches | Short, smooth; moderate shedding |
Coat Type Possibilities and the Hypoallergenic Question
Is the Shih Tzu Terrier mix hypoallergenic? The short answer: not reliably. Both Shih Tzus and Yorkshire Terriers have hair rather than fur and are considered low-shedding breeds, which is why Shorkies are often marketed as hypoallergenic. However, no dog is truly hypoallergenic — allergies are triggered by dander (dead skin cells), saliva, and urine proteins, not just shed hair.
If the terrier parent is a Yorkie, the F1 puppies have a reasonable chance of being low-shedding. But if the terrier parent is a Jack Russell, Rat Terrier, or Westie, expect moderate shedding from the mix. Even within a single litter, some puppies may inherit a low-shed coat while siblings shed noticeably. If allergy management is a priority, spend time with the specific puppy before committing, and understand that allergic reactions are individual.
Coat texture possibilities include:
- Silky-long (Shih Tzu-dominant or Yorkie-dominant): Requires daily brushing and professional grooming every 6–8 weeks
- Wiry-medium (terrier-dominant): Needs brushing 2–3 times per week, hand-stripping or clipping every 8–12 weeks
- Short-smooth (rare, from short-coated terrier parents): Brush weekly, minimal grooming costs
Temperament: Best-Case and Challenging Scenarios
The temperament of Shih Tzu Terrier mix dogs spans a wide spectrum. The Shih Tzu contributes a calm, people-oriented, low-drive disposition. The terrier side adds alertness, independence, and prey drive. How these blend depends on the individual puppy's genetic expression and early socialization.
Your mix inherits the Shih Tzu's affectionate nature and the Yorkie's alertness without excessive barking. The dog is friendly with strangers, content with 30–45 minutes of daily activity, adapts well to apartment living, and bonds closely with family. Trainable with positive reinforcement methods and food motivation.
Your mix inherits the terrier's high prey drive and vocal tendencies combined with Shih Tzu stubbornness. The dog chases cats and small animals, barks excessively at doorbells and passersby, shows resource guarding tendencies, and resists training without high-value rewards. May not be reliable off-leash and could be reactive toward other dogs if not socialized early.
Early socialization — exposure to diverse people, sounds, surfaces, and other animals between 3 and 14 weeks of age — is the single most impactful thing you can do to shape temperament. Enroll in a force-free puppy kindergarten class by 8–10 weeks. Never use shock collars, prong collars, or alpha rolls; these methods increase fear and reactivity in small breeds.
Family Compatibility
Shih Tzu Terrier mixes suit households with adults or families with children over age 8. Due to their small size (typically under 15 lb), they are fragile and can be injured by rough handling — a toddler dropping or squeezing a puppy can cause fractures. They are generally poor fits for homes with pet rodents, birds, or cats (depending on prey drive inheritance).
Health Considerations: Separating Myth from Reality
One of the most persistent claims about designer dogs is "hybrid vigor" — the idea that mixed breeds are automatically healthier than purebreds. The reality is more nuanced. While genetic diversity can reduce the risk of certain recessive disorders, a Shih Tzu Terrier mix can inherit health conditions from either parent breed. Crossbreeding does not eliminate risk; it changes which risks are in play.
According to the Merck Veterinary Manual, mixed-breed dogs do show a modest reduction in some inherited conditions compared to heavily inbred purebred lines, but this benefit is not guaranteed and diminishes if breeders use unhealthy parent stock.
| Condition | Inherited From | Prevalence / Risk Level | What to Watch For |
|---|---|---|---|
| Brachycephalic Obstructive Airway Syndrome (BOAS) | Shih Tzu | High if flat face inherited | Noisy breathing, exercise intolerance, heat sensitivity, snoring |
| Patellar Luxation | Both parents | Common in small breeds (estimated 5–10%) | Skipping gait, hind leg held up, intermittent lameness |
| Dental Disease | Both parents | Very high — over 80% of small dogs by age 3 | Bad breath, red gums, loose teeth, difficulty eating |
| Portosystemic Shunt (Liver Shunt) | Yorkshire Terrier | Low-to-moderate (higher in Yorkie lines) | Stunted growth, disorientation after meals, seizures |
| Intervertebral Disc Disease (IVDD) | Shih Tzu (long-backed types) | Moderate | Back pain, reluctance to jump, hind limb weakness or paralysis |
| Eye Conditions (PRA, dry eye, cataracts) | Both parents | Moderate | Cloudy eyes, bumping into objects, excessive eye discharge |
Responsible breeders should provide OFA (Orthopedic Foundation for Animals) or PennHIP certifications for patellar luxation and cardiac evaluations for both parent dogs. Ask for documentation — verbal assurances are not enough.
Grooming and Daily Care Requirements
Grooming needs for Shih Tzu Terrier mix dogs vary dramatically based on which coat type the individual inherits. Plan for the higher-maintenance scenario when budgeting.
Coat Care by Type
- Long/silky coat: Daily brushing with a slicker brush and metal comb to prevent matting. Professional grooming every 6–8 weeks ($50–$90 per session). Bathing every 2–3 weeks with a dog-specific moisturizing shampoo. Expect $400–$720 annually in grooming costs.
- Wiry/medium coat: Brush 2–3 times per week. Professional clip or hand-strip every 8–12 weeks ($40–$70 per session). Lower matting risk than silky coats. Expect $200–$420 annually.
- Short/smooth coat: Weekly brushing with a rubber curry brush. Occasional baths. Minimal professional grooming needed. Expect $50–$100 annually.
Beyond the Coat
- Dental care: Daily tooth brushing with enzymatic dog toothpaste is non-negotiable for small breeds. Budget for professional dental cleanings under anesthesia every 1–2 years ($300–$700 per cleaning).
- Eye care: If your mix inherits the Shih Tzu's prominent eyes and facial folds, clean eye area daily with a damp cloth or veterinary eye wipe to prevent tear staining and fold infections.
- Nail trims: Every 2–3 weeks. Small dogs that don't walk on abrasive surfaces (concrete) need more frequent trims to prevent overgrowth and posture problems.
- Ear cleaning: Weekly checks; clean with a veterinarian-recommended ear cleaner if floppy ears are inherited (Shih Tzu trait). Floppy ears trap moisture and increase infection risk.
Cost: Purchase Price, Adoption, and Annual Budget
How much does a Shih Tzu Terrier mix cost? Pricing varies significantly based on source, location, and breeder reputation.
| Source | Price Range | What's Typically Included |
|---|---|---|
| Responsible breeder (health-tested parents) | $800–$2,500 | Health guarantees, first vaccinations, deworming, microchip, spay/neuter contract, take-back clause |
| Backyard breeder / online marketplace | $300–$800 | Variable — often no health testing, no guarantees |
| Rescue / shelter adoption | $100–$400 | Spay/neuter, vaccinations, microchip, behavioral assessment |
First-year total cost estimate: $2,200–$4,800 including acquisition, initial veterinary exams, vaccinations (DHPP series at 8, 12, and 16 weeks, rabies at 12–16 weeks), spay/neuter if not included, supplies (crate, harness, grooming tools), food, and pet insurance enrollment.
Annual ongoing costs (after year one): $1,400–$2,800 covering food ($25–$50/month for a small breed on quality AAFCO-approved kibble), grooming, routine veterinary care (annual exam, vaccines, heartworm/flea/tick prevention), dental cleanings, and pet insurance premiums ($30–$60/month for small breeds).
Shih Tzu Terrier mixes are available through breed-specific rescues. Check the ASPCA adoption portal and local Shih Tzu or terrier rescue organizations. Adult mixed breeds from rescues let you see the dog's actual temperament and size before committing — a significant advantage over puppy guessing.
Who This Mix Suits Best (and Who Should Look Elsewhere)
Based on the trait range and care requirements, here's a practical fit assessment:
- Apartment or condo dwellers (these dogs adapt well to smaller spaces with daily walks)
- Seniors or retirees seeking a companion dog with moderate energy
- Families with children age 8+ who understand gentle handling
- First-time dog owners willing to invest in puppy socialization classes
- People who want an alert dog that will bark at strangers but isn't aggressive
- Households without small pets (rodents, birds, cats with nervous temperaments)
- Families with toddlers or very young children (fragility risk)
- Homes with pet rodents, rabbits, or birds (terrier prey drive)
- People who work 8+ hours away from home daily (separation anxiety risk)
- Those seeking a reliably off-leash hiking companion (prey drive makes recall unreliable)
- Anyone who wants a guaranteed temperament or appearance (too much variability)
- People unable to commit to regular grooming budgets ($200–$720/year)
Exercise Requirements
Most Shih Tzu Terrier mixes need 30–45 minutes of daily exercise, split into two walks plus indoor play. However, if the terrier parent was a Jack Russell, expect to provide 45–60 minutes including active play sessions like fetch or flirt pole work. Mental stimulation through puzzle feeders, snuffle mats, and short training sessions (5–10 minutes, 2–3 times daily) prevents boredom-related barking and destructive behavior.
Frequently Asked Questions
What two breeds make up a Shih Tzu Terrier mix?
A Shih Tzu Terrier mix is a cross between a purebred Shih Tzu and one of several terrier breeds. The most common combination is Shih Tzu × Yorkshire Terrier (called a Shorkie). Other terrier parents include Jack Russell Terriers, West Highland White Terriers, Rat Terriers, and occasionally Cairn Terriers or Norfolk Terriers. Always confirm which specific terrier breed was used, as this significantly impacts the mix's size, energy level, and coat type.
How big will my Shih Tzu Terrier mix get?
Most Shih Tzu Terrier mixes fall between 7–16 lb (3.2–7.3 kg) and 8–14 inches at the shoulder. The Shorkie (Yorkie parent) tends toward the smaller end at 7–12 lb, while mixes with Jack Russell or Westie parents lean toward 12–18 lb. Ask the breeder for the weights of both parent dogs — the puppy's adult weight typically falls between the two parents' weights, though this is not guaranteed.
What will the temperament be like?
Expect a blend of affection and alertness with moderate-to-high energy. The Shih Tzu side contributes a people-loving, lap-dog disposition, while the terrier side adds boldness, vocalization, and prey drive. Individual variation is significant — one puppy may be calm and cuddly while a littermate is feisty and independent. Early socialization (3–14 weeks) and positive reinforcement training are critical for shaping a well-adjusted adult dog.
Is this mix hypoallergenic or low-shedding?
Not reliably. If both parents are low-shedding breeds (Shih Tzu × Yorkie), the puppies have a reasonable chance of being low-shedding. However, no dog is truly hypoallergenic — allergies are triggered by dander and saliva proteins. If the terrier parent is a shedding breed like a Jack Russell, expect moderate shedding. Spend time with the specific puppy before committing if allergies are a concern, and consider consulting an allergist.
What health issues might this mix inherit?
Key conditions to screen for include brachycephalic obstructive airway syndrome (BOAS, if flat-faced), patellar luxation (kneecap dislocation common in small breeds), dental disease (very high prevalence in toy breeds), eye conditions like progressive retinal atrophy and dry eye, and portosystemic shunts (liver shunts, particularly from Yorkie lines). Request OFA health testing documentation from breeders and schedule a veterinary wellness exam promptly after acquisition.
How much does a Shih Tzu Terrier mix cost?
From a responsible breeder with health-tested parents, expect to pay $800–$2,500. Backyard breeders and online sellers may charge $300–$800 but typically provide no health guarantees. Rescue adoption fees range from $100–$400 and often include spay/neuter and vaccinations. Factor in first-year costs of $2,200–$4,800 total, and annual ongoing costs of $1,400–$2,800.
Are Shih Tzu Terrier mixes easy to train?
They are moderately trainable but require patience. The Shih Tzu's mild stubbornness combined with terrier independence means these dogs respond best to short, positive reinforcement sessions using high-value treats (small pieces of chicken, cheese, or commercial training treats). Keep sessions to 5–10 minutes, 2–3 times daily. Force-free methods work best — aversive tools like shock collars damage trust and increase anxiety in sensitive small breeds.
Do Shih Tzu Terrier mixes bark a lot?
It depends on which parent's traits dominate. Terriers are generally more vocal than Shih Tzus, so mixes leaning toward the terrier side tend to bark at doorbells, passersby, and other dogs. Consistent training using counter-conditioning and desensitization can manage excessive barking. Providing adequate mental stimulation and exercise also reduces attention-seeking vocalization.
