Shih Tzu Terrier Dog: Complete Breed Mix Guide for Prospective Owners

If you've been researching the Shih Tzu Terrier dog, you've likely discovered that this isn't a single standardized breed but rather a designer cross — typically a Shih Tzu bred with one of several terrier breeds, most commonly the Yorkshire Terrier (producing the popular "Shorkie"), Jack Russell Terrier, or West Highland White Terrier. The result is a small, spirited companion dog that blends the Shih Tzu's affectionate lap-dog nature with a terrier's spunky independence.

Because the Shih Tzu Terrier dog is a mixed breed, traits can vary significantly depending on which terrier parent is involved and which generation of cross you're looking at (F1, F1B, or multigen). This guide breaks down what you can realistically expect across the most common Shih Tzu–Terrier pairings so you can decide if this mix fits your household.

Origin and History: Where the Shih Tzu Terrier Dog Comes From

The Shih Tzu Terrier dog emerged during the designer dog boom of the late 1990s and early 2000s in the United States. Breeders began crossing the ancient Shih Tzu — a breed developed in Chinese imperial courts as a companion and alert dog, with documented lineage tracing back to Tibet around the 7th century — with various terrier breeds to create smaller companion dogs with more energetic personalities.

The most popular pairing is the Shih Tzu × Yorkshire Terrier (often called the Shorkie), which gained AKC Foundation Stock Service recognition as a designer breed. The Yorkshire Terrier originated in northern England in the mid-1800s as a ratting dog in textile mills, while the Shih Tzu's history stretches back over 1,000 years as a cherished palace companion. This combination produces a dog that wants to cuddle but also has a playful, alert streak.

Less common pairings include the Shih Tzu × Jack Russell Terrier (sometimes called a "Jack Tzu") and the Shih Tzu × West Highland White Terrier ("Westie Tzu"), each producing noticeably different temperaments and physical traits. The Jack Russell cross tends to be more energetic and driven, while the Westie cross often inherits a sturdier build and a more confident demeanor.

Physical Characteristics: What a Shih Tzu Terrier Dog Looks Like

Because this is a mixed breed, appearance varies considerably even within the same litter. However, most Shih Tzu Terrier dogs share certain traits inherited from both parent lines.

Size Breakdown by Terrier Parent

Cross Type	Weight (lb / kg)	Height (in / cm)	Build
Shih Tzu × Yorkie (Shorkie)	7–12 lb / 3.2–5.4 kg	8–10 in / 20–25 cm	Petite, fine-boned
Shih Tzu × Jack Russell (Jack Tzu)	10–16 lb / 4.5–7.3 kg	10–12 in / 25–30 cm	Sturdy, athletic
Shih Tzu × Westie (Westie Tzu)	10–15 lb / 4.5–6.8 kg	9–11 in / 23–28 cm	Compact, solid

Coat and Color

Coat texture depends heavily on which terrier parent contributes more genetically. Shorkies typically inherit a long, silky coat that may be straight or slightly wavy, often in black-and-tan, gold-and-white, or parti-color patterns. Jack Tzu crosses tend toward a shorter, denser coat that may have some wiry texture, commonly in white with brown or black patches. Westie Tzu crosses often have a medium-length, slightly harsh outer coat with a softer undercoat, typically in white or cream.

Most Shih Tzu Terrier dogs have a brachycephalic (short-muzzled) to mesocephalic (medium-muzzled) head shape, dark round eyes, and ears that may be floppy (Shih Tzu influence) or semi-erect (terrier influence). The tail is usually carried over the back or in a gentle curve.

Temperament and Personality: Living With a Shih Tzu Terrier Dog

The Shih Tzu Terrier dog's personality is where the mix really shines — and where the terrier influence creates interesting variation from the purebred Shih Tzu's famously mellow disposition. Here are the core traits you can expect:

Exercise and Activity Needs

The Shih Tzu Terrier dog needs 30–45 minutes of structured activity daily, split across two or three sessions. This is notably more than a purebred Shih Tzu (which typically needs 20–30 minutes) but less than a pure terrier breed.

Recommended Daily Activity Plan

Activity	Duration	Notes
Morning walk	15–20 minutes	Leash walk at a comfortable pace; avoid hot pavement in summer
Indoor play session	10–15 minutes	Fetch with soft toys, tug, or puzzle feeder games
Evening walk or yard time	10–15 minutes	Sniffari-style walk allowing exploration and mental stimulation
Training practice	5–10 minutes	Short, positive reinforcement sessions; trick training works well

Important for brachycephalic-leaning dogs: If your Shih Tzu Terrier dog has a shorter muzzle (inheriting more Shih Tzu facial structure), avoid vigorous exercise in temperatures above 80°F (27°C) and watch for signs of respiratory distress — excessive panting, blue-tinged gums, or reluctance to continue walking. The AKC notes that brachycephalic breeds are at higher risk for heat-related emergencies.

Common Health Issues in Shih Tzu Terrier Dogs

Mixed breeds can benefit from what's known as hybrid vigor — the tendency for crossbred dogs to have lower incidence of certain inherited conditions compared to their purebred parents. However, the Shih Tzu Terrier dog can still inherit health problems from either parent line. Always consult your veterinarian for breed-appropriate health screening and preventive care.

Condition	Description	Prevalence / Risk Level	Prevention & Management
Patellar Luxation	Kneecap slips out of position, causing intermittent limping or "skipping" gait	Common in small breeds — estimated 5–10% of toy/small dogs affected	Maintain healthy weight; avoid high jumps; surgical correction for Grade III–IV
Brachycephalic Obstructive Airway Syndrome (BOAS)	Narrowed airways causing breathing difficulty, snoring, exercise intolerance	Moderate risk — higher if dog inherits shorter Shih Tzu muzzle	Weight management; harness instead of collar; avoid heat; surgical options for severe cases
Dental Disease	Periodontal disease, tooth crowding, early tooth loss	Very common — up to 80% of small dogs show signs by age 3 (AVMA)	Daily tooth brushing; annual veterinary dental cleanings; dental chews as supplement
Eye Conditions (Keratoconjunctivitis Sicca / Proptosis)	Dry eye and risk of eye injury due to prominent, shallow-set eyes	Moderate risk — especially in dogs with Shih Tzu–type eye structure	Regular eye checks; keep hair trimmed around eyes; artificial tears if prescribed
Portosystemic Shunt (Liver Shunt)	Abnormal blood vessel bypassing the liver, causing toxin buildup	Low to moderate — seen in both Shih Tzus and Yorkshire Terriers	Veterinary screening if symptoms appear (stunted growth, seizures after eating); surgical or medical management

When to see the vet immediately: Difficulty breathing or persistent coughing; sudden blindness or eye trauma; inability to bear weight on a leg; seizures; vomiting or diarrhea lasting more than 24 hours; collapse or extreme lethargy.

Grooming Requirements

The Shih Tzu Terrier dog requires a significant grooming commitment — this is not a low-maintenance coat, regardless of which terrier parent is involved.

Grooming Schedule and Tools

Task	Frequency	Tools Needed
Brushing (full coat)	Daily for long coats; 3× weekly for shorter coats	Slicker brush, metal comb, detangling spray
Professional grooming	Every 6–8 weeks	Professional groomer; budget $50–$85 per session
Bathing	Every 3–4 weeks (or as needed)	Dog-specific oatmeal or hypoallergenic shampoo
Face cleaning	Daily	Unscented pet wipes or damp cloth for tear stains and food debris
Ear cleaning	Weekly	Veterinary ear cleaner; cotton balls (never cotton swabs)
Nail trimming	Every 2–3 weeks	Guillotine or scissor-style nail clippers; styptic powder on hand
Teeth brushing	Daily (minimum 3× weekly)	Dog toothbrush and enzymatic toothpaste (never human toothpaste)

Pro tip: Many owners of Shih Tzu Terrier dogs opt for a "puppy cut" or "teddy bear cut" — trimming the coat to 1–2 inches all over — which dramatically reduces daily brushing time from 15 minutes to about 5 minutes and helps prevent painful matting. If you choose to keep the coat long, invest in a high-quality slicker brush (the Chris Christensen Big G series is a groomer favorite, around $45–$60) and commit to thorough daily brushing down to the skin.

Training and Intelligence

The Shih Tzu Terrier dog is intelligent but not necessarily biddable — meaning they understand what you're asking but may decide it's not worth their effort. This is the combination of the Shih Tzu's independent companion-dog heritage (they were bred to be charming, not to work) and the terrier's self-directed problem-solving nature.

Trainability rating: Moderate (3 out of 5)

Effective Training Methods

Only positive reinforcement and force-free training methods are appropriate for this mix. The Shih Tzu Terrier dog is sensitive to tone and body language — harsh corrections or aversive tools like shock collars or prong collars will damage your relationship and likely increase fear-based behaviors.

• Use high-value treats: Small pieces of freeze-dried chicken or cheese work far better than standard training treats for motivating this mix.
• Keep sessions short: 5–10 minutes maximum, 2–3 times per day. These dogs lose interest quickly in repetitive drills.
• Counter-conditioning for barking: Teach a "quiet" cue by rewarding silence rather than punishing barking. Pair the arrival of triggers (doorbell, strangers) with treats to change the emotional response.
• Crate training early: Essential for housebreaking and separation anxiety prevention. Use gradual desensitization — never use the crate as punishment.
• Socialization window: Between 8–16 weeks, expose your puppy to diverse people, surfaces, sounds, and other vaccinated dogs. The AVMA recommends structured socialization during this critical period.

Family Suitability: Kids, Pets, and Apartment Living

With Children

The Shih Tzu Terrier dog does best with children aged 8 and older who understand how to handle small dogs gently. These dogs are not aggressive, but their small size makes them vulnerable to injury from rough handling — a toddler squeezing too hard or dropping the dog can cause fractures or spinal injuries. Teach children to let the dog approach them, to avoid picking the dog up without adult supervision, and to respect the dog's crate and sleep space.

With Other Pets

Early socialization is key. Shih Tzu Terrier dogs raised alongside cats or other dogs typically coexist peacefully. However, the terrier heritage may produce a higher prey drive toward small animals like hamsters, gerbils, or birds. Dog-to-dog introductions should be gradual and supervised, especially with larger breeds that could accidentally injure a small dog during play.

Apartment Living

This is an excellent apartment dog. Their moderate exercise needs, small size, and preference for being near their people make them well-suited to condos and apartments. The primary concern is barking — if you share walls with neighbors, invest time in bark management training early. A white noise machine near shared walls and keeping curtains closed to reduce visual triggers can help.
