Poodle Shih Tzu Mix: Complete Poo-Shi Breed Guide for Owners
Everything you need to know about the Poodle Shih Tzu mix (Poo-Shi): size, coat types, temperament variability, health risks, grooming, and 2026 pricing.
What Is a Poodle Shih Tzu Mix?
The Poodle Shih Tzu mix — most commonly called the Poo-Shi or Shih-Poo — is a designer crossbreed that pairs the intelligence and low-shedding coat of the Poodle with the affectionate, laid-back nature of the Shih Tzu. This small companion dog typically weighs between 8 and 18 pounds (3.6–8.2 kg) and stands 8 to 15 inches (20–38 cm) tall, though individual size depends heavily on which Poodle variety (Toy or Miniature) was used in the cross.
Unlike purebred dogs governed by a written breed standard, every Poodle Shih Tzu mix is a genetic roll of the dice. Some puppies in the same litter may look and behave dramatically differently. This guide breaks down what you can reasonably expect — and where the surprises tend to hide.

Parent Breed Breakdown: Poodle vs. Shih Tzu
Understanding the Poodle Shih Tzu mix starts with understanding the two breeds behind it. Each parent contributes a distinct set of traits, and the resulting puppies can lean heavily toward one parent or land somewhere in between.
| Trait | Poodle (Toy/Miniature) | Shih Tzu |
|---|---|---|
| AKC Group | Non-Sporting / Toy | Toy |
| Weight | 4–15 lb (1.8–6.8 kg) | 9–16 lb (4.1–7.3 kg) |
| Height | 10–15 in (25–38 cm) | 9–10.5 in (23–27 cm) |
| Coat | Curly, single-layer, hair-like | Long, straight to slightly wavy double coat |
| Shedding | Very low | Low to moderate |
| Temperament | Highly intelligent, active, alert | Affectionate, outgoing, less driven |
| Trainability | Exceptional — ranks #2 in canine intelligence | Moderate — can be stubborn, food-motivated |
| Exercise Needs | 30–60 min/day | 20–30 min/day |
| Origin | Germany/France — water retriever | Tibet/China — palace companion |
| Lifespan | 10–18 years | 10–16 years |
The Poodle side brings sharp intelligence, athletic ability, and a low-shedding curly coat. According to the AKC breed standard, Poodles rank among the most trainable breeds in existence. The Shih Tzu side contributes a calmer disposition, a strong desire for physical closeness, and a brachycephalic (short-faced) skull structure that affects everything from breathing to dental health.
Generations Explained: F1, F1B, F2, and Multigen
- F1 (First Generation): 50% Poodle × 50% Shih Tzu. Maximum genetic diversity, but the most unpredictable traits. One puppy may have a tight Poodle curl while a littermate has a straight Shih Tzu coat.
- F1B (First Generation Backcross): An F1 Poo-Shi bred back to one parent breed — usually the Poodle to increase the chance of a low-shedding coat. Approximately 75% one breed, 25% the other.
- F2 (Second Generation): Two F1 Poo-Shis bred together. Genetic variability remains high; coat type and size can swing widely even within one litter.
- Multigen (F3+): Multiple generations of Poo-Shi to Poo-Shi breeding. Traits become somewhat more predictable, but this is still not a recognized breed with a fixed standard.
Most Poodle Shih Tzu mixes available from breeders are F1 or F1B. If low shedding is your top priority — say, because a household member has mild allergies — an F1B backcrossed to a Poodle gives you the best odds, though there is never a guarantee. Reputable breeders should disclose which generation they produce and be transparent about the variability involved.
Size, Coat, and Physical Trait Variability
Because the Poodle comes in three sizes (Standard, Miniature, and Toy), the size of a Poodle Shih Tzu mix depends entirely on which Poodle parent was used. Most breeders use Toy or Miniature Poodles to keep the offspring small.
| Poodle Parent | Expected Mix Weight | Expected Mix Height |
|---|---|---|
| Toy Poodle (4–6 lb) | 8–12 lb (3.6–5.4 kg) | 8–11 in (20–28 cm) |
| Miniature Poodle (10–15 lb) | 12–18 lb (5.4–8.2 kg) | 11–15 in (28–38 cm) |
Coat possibilities span a wide spectrum. An F1 puppy might inherit the Poodle's tight, single-layer curls (lowest shedding), the Shih Tzu's longer, flowing double coat (moderate shedding), or a wavy middle-ground texture. Curly coats require professional grooming every 4–8 weeks; straighter Shih Tzu-type coats need daily brushing to prevent mats but can be trimmed shorter for easier upkeep.
| Trait | Predictability | Notes |
|---|---|---|
| General size range | Moderate | Depends on Poodle parent size; F1 varies more than multigen |
| Coat texture | Low | Curly, wavy, or straight — can differ within a single litter |
| Shedding level | Low | No guarantees; F1B to Poodle improves odds |
| Affection level | High | Both parent breeds are companion-oriented |
| Trainability | Moderate | Poodle intelligence vs. Shih Tzu stubbornness — varies by individual |
| Brachycephalic features | Moderate | Some inherit the Shih Tzu's short muzzle; others get a longer Poodle snout |
| Barking tendency | Moderate | Both breeds can be vocal; early training helps |
Temperament: Best-Case and Challenging Scenarios
The Poodle Shih Tzu mix inherits traits from two companion breeds, so the best-case scenario is a dog that is deeply bonded to its people, eager to please (thanks to Poodle intelligence), and content to curl up on the couch for long stretches (thanks to the Shih Tzu's relaxed nature). Well-socialized Poo-Shis tend to be friendly with visitors, good with gentle children, and adaptable to apartment living.
The challenging scenario is a dog that inherits the Shih Tzu's stubborn streak combined with the Poodle's alertness and sensitivity. This can produce a dog that barks at every sound, becomes anxious when left alone (separation distress is common in both parent breeds), or resists training sessions that feel repetitive. Some individuals inherit the Shih Tzu's wariness of strangers, which can manifest as fearful barking or hiding if the puppy wasn't adequately socialized during the critical 3-to-14-week window.
Positive reinforcement training — using treats, praise, and play as rewards — works well for this cross. Force-free methods like those recommended by the American Veterinary Society of Animal Behavior are essential; harsh corrections can shut down a sensitive Poo-Shi or trigger fear-based reactivity.
Exercise and Mental Stimulation
Plan for 20–40 minutes of daily activity, split between a short walk and indoor play. The Poodle side may want more mental engagement — puzzle feeders, short trick-training sessions, or scent games work well. The Shih Tzu side may prefer a leisurely sniff-walk over vigorous exercise. Watch your individual dog's cues: brachycephalic-leaning dogs overheat more easily and should avoid exercise in temperatures above 80°F (27°C).
Health Considerations: Hybrid Vigor vs. Reality
One of the most persistent myths about designer dogs is that hybrid vigor eliminates all health problems. This is not true. While crossbreeding can reduce the risk of conditions caused by recessive genes shared within a single breed, a Poodle Shih Tzu mix can still inherit any condition that affects either parent breed. The Merck Veterinary Manual notes that hybrid vigor is most effective when the parent breeds have different genetic disease profiles — and Poodles and Shih Tzus share some overlapping risks.
Inherited Health Risks From Both Parent Breeds
| Condition | From Which Parent | Prevalence / Notes |
|---|---|---|
| Brachycephalic Obstructive Airway Syndrome (BOAS) | Shih Tzu | Affects dogs inheriting the short muzzle; causes snoring, exercise intolerance, heat sensitivity |
| Patellar Luxation | Both | Kneecap slips out of place; common in small breeds; grades I–IV; surgery for severe cases ($1,500–$3,000 per knee) |
| Progressive Retinal Atrophy (PRA) | Both | Gradual blindness; DNA tests available for both breeds; responsible breeders screen parents |
| Hip Dysplasia | Poodle (Miniature) | Less common in toy breeds but possible; OFA screening recommended |
| Dental Disease | Both (especially Shih Tzu) | Small mouths crowd teeth; daily brushing and annual dental cleanings are essential ($400–$800 per cleaning under anesthesia) |
| Allergies / Skin Sensitivities | Poodle | Environmental and food allergies; manifests as itching, ear infections, paw licking |
| Keratoconjunctivitis Sicca (Dry Eye) | Shih Tzu | Reduced tear production; requires lifelong medicated eye drops |
| Intervertebral Disc Disease (IVDD) | Both | Disc herniation causing pain or paralysis; risk increases with obesity and jumping from furniture |
Seek emergency veterinary care if your Poo-Shi shows any of these red flags: difficulty breathing or blue-tinged gums (possible BOAS crisis or heart issue), sudden hind-limb weakness or inability to walk (possible IVDD), persistent vomiting or a distended abdomen, or seizures. Always consult your veterinarian about any ongoing symptoms rather than attempting home diagnosis.
Recommended Health Screening
Responsible breeders of Poodle Shih Tzu mixes should test parent dogs for:
- Patellar evaluation — OFA (Orthopedic Foundation for Animals) certification
- Ophthalmologist evaluation — CERF (Canine Eye Registration Foundation) exam for PRA and other eye conditions
- Hip evaluation — OFA radiographs, especially if a Miniature Poodle is the parent
- DNA panel — for breed-specific mutations including PRA-prcd (progressive rod-cone degeneration)
Grooming: What Your Poo-Shi's Coat Will Need
Grooming requirements depend almost entirely on which coat type your individual dog inherits:
- Poodle-type curly coat: Professional grooming every 4–6 weeks ($50–$90 per session). Daily brushing with a slicker brush to prevent matting at the skin. Regular ear cleaning — floppy, hairy ears trap moisture and invite infection.
- Shih Tzu-type long coat: Daily brushing with a pin brush and metal comb. Professional grooming every 6–8 weeks if kept long, or every 4–6 weeks if clipped short. Pay special attention to the face — tear staining is common in Shih Tzu-influenced dogs and requires daily wiping with a damp cloth or commercial tear-stain remover.
- Wavy mixed coat: The most common F1 outcome. Brush 3–4 times per week and schedule professional grooming every 6–8 weeks. This coat type tends to mat behind the ears and in the armpits, so check those areas regularly.
Regardless of coat type, budget for $400–$900 per year in professional grooming, plus at-home supplies: a quality slicker brush ($15–$30), metal comb ($8–$15), dog-safe shampoo ($10–$20), and ear cleaning solution ($8–$15). Dental care is non-negotiable for small breeds — brush teeth daily with enzymatic dog toothpaste and schedule veterinary dental cleanings annually.
Cost, Availability, and Finding a Poodle Shih Tzu Mix
The Poodle Shih Tzu mix is not recognized by the AKC as a purebred, so you won't find AKC registration papers. However, some breeders register with designer dog registries like the ACHC (American Canine Hybrid Club) or IDCR (International Designer Canine Registry).
Price Breakdown
| Source | Cost Range | What's Included |
|---|---|---|
| Responsible small-scale breeder | $800–$2,500 | Health-tested parents, first vaccines, deworming, health guarantee, take-back clause |
| High-volume commercial breeder | $400–$1,200 | Variable — often no health testing; higher risk of inherited conditions |
| Rescue or shelter adoption | $50–$400 | Spay/neuter, vaccines, microchip; availability is limited but check breed-specific rescues for both Poodles and Shih Tzus |
First-year ownership costs beyond the purchase price typically run $1,800–$3,500, covering veterinary exams, vaccinations (DHPP and rabies series), spay/neuter ($200–$500), grooming, food, supplies, and pet insurance. Small-breed pet insurance premiums average $30–$50/month in 2026, depending on your deductible and location.
Adoption as an Alternative
While dedicated Poo-Shi rescues don't exist, checking Petfinder and searching for "Shih Tzu mix" or "Poodle mix" in your area can surface dogs in need of homes. Breed-specific rescues for Shih Tzus and Poodles also occasionally take in mixed-breed dogs. Adopting gives you the advantage of meeting an adult dog whose size, coat, and temperament are already established — removing much of the guesswork.
Who Is the Poodle Shih Tzu Mix Best Suited For?
This mix works well for:
- Apartment dwellers: Small size and moderate energy make them well-suited to smaller living spaces, provided they get daily walks.
- Seniors or less active owners: The Shih Tzu's lower exercise needs often dominate, making this a good couch companion.
- Families with older children (8+): These are small, somewhat fragile dogs. Toddlers and rough-playing young children can accidentally injure them.
- First-time dog owners: Generally manageable temperament, though the potential for stubbornness means patience with training is essential.
- People with mild allergies: An F1B backcrossed to a Poodle offers the best chance of a low-allergen coat, but always spend time with the specific dog before committing.
This mix is less ideal for households that are away for long hours (separation anxiety risk), families with very young children, or anyone who wants a dog for hiking or high-intensity outdoor activities.
Frequently Asked Questions
What two breeds make up the Poodle Shih Tzu mix?
The Poodle Shih Tzu mix is a cross between a Poodle (typically Toy or Miniature) and a Shih Tzu. The specific Poodle size used affects the offspring's adult weight and height.
How big will my Poodle Shih Tzu mix get?
Most fall between 8 and 18 pounds (3.6–8.2 kg) and 8 to 15 inches (20–38 cm) tall at the shoulder. The exact size depends on whether a Toy or Miniature Poodle was one parent, and which generation the dog belongs to.
Is the Poodle Shih Tzu mix hypoallergenic?
No dog is truly hypoallergenic, and this mix is no exception. Some individuals inherit the Poodle's low-shedding, hair-like coat that produces fewer airborne allergens, while others inherit a Shih Tzu-type coat that sheds more. An F1B generation backcrossed to a Poodle gives the best odds for allergy sufferers, but always spend extended time with the individual dog before committing.
What health issues might a Poodle Shih Tzu mix inherit?
Key conditions include brachycephalic airway syndrome (if the short muzzle is inherited), patellar luxation, progressive retinal atrophy, dental disease, IVDD, and skin allergies. Hybrid vigor may reduce some risks but does not eliminate them. Ask breeders for documentation of parent health screenings.
How much does a Poodle Shih Tzu mix cost?
From a responsible breeder, expect to pay $800–$2,500. Rescue adoption fees range from $50–$400. First-year care costs add $1,800–$3,500 on top of the purchase price.
What will the temperament be like?
Most Poodle Shih Tzu mixes are affectionate, people-oriented, and adaptable. Expect a dog that bonds closely with its family and enjoys companionship. Trainability varies — some inherit the Poodle's eagerness to learn, while others lean toward the Shih Tzu's independent streak. Early socialization (starting at 8 weeks) and consistent positive reinforcement training produce the best outcomes.
Can this mix be left alone for long periods?
Generally, no. Both Poodles and Shih Tzus are companion breeds prone to separation distress. If you work long hours, consider a dog walker, doggy daycare, or a more independent breed. Most Poo-Shis do best with no more than 4–5 hours alone at a stretch.
