The Shih Tzu is one of the most beloved toy breeds in the world. Known for its luxurious coat, charming demeanor, and small stature, this dog captures hearts quickly. But what happens when your adorable puppy grows up? This article offers a deep dive into everything you need to know about the full grown Shih Tzu—from size and weight to grooming needs and personality traits.
How Big Does a Full Grown Shih Tzu Get?
When your Shih Tzu reaches adulthood, you’ll notice that their size stabilizes and their features fully develop. Most grown Shih Tzu dogs fall into a consistent size range:
- Height: 8 to 11 inches tall at the shoulder
- Weight: 9 to 16 pounds, depending on diet, activity level, and genetics
- Length: Usually 15 to 17 inches from chest to rear
This compact build makes them perfect for apartment living while still being sturdy enough to enjoy outdoor play.
Growth Timeline of a Shih Tzu
To better understand your dog’s development, here is a general timeline of their growth stages:
0-8 Weeks
Shih Tzus are born tiny and fragile. At this stage, they rely entirely on their mother. Socialization starts around week 4.
2-6 Months
This is the phase of rapid development. The puppy will begin to look more like a small dog than a newborn. Training and socialization are crucial during this period.
6-10 Months
The puppy’s growth rate begins to slow. Their final adult weight starts to become more apparent.
10-12 Months
Most Shih Tzus are considered full grown by their first birthday. Some may continue to fill out or grow thicker coats into the 14- to 16-month range.
Physical Appearance of a Full Grown Shih Tzu
Coat and Color
One of the breed’s most defining features is its long, flowing double coat. A Shih Tzu full grown can come in various colors, including:
- Gold
- White
- Black
- Brindle
- Liver
- Blue
The coat requires regular brushing to prevent tangles and mats. Some owners opt for a shorter “puppy cut” for easier maintenance.
Eyes and Face
Full grown Shih Tzus have large, round eyes that express curiosity and affection. Their flat face and short muzzle give them a distinctive, slightly pushed-in look.
Tail
The tail is long and curled over the back—a unique trait that adds to their royal appearance.
Personality and Temperament
The personality of a grown Shih Tzu is one of its most delightful aspects. These dogs are often described as:
- Affectionate and loving
- Loyal to their families
- Friendly toward strangers and other pets
- Playful but not hyper
They thrive in social environments and dislike being left alone for long periods. Despite their small size, they have a courageous and confident spirit.
Training and Behavior of a Full Grown Shih Tzu
House Training
Though intelligent, Shih Tzus can be a bit stubborn. Consistent, positive reinforcement is key to successful house training.
Obedience
A full grown Shih Tzu responds well to commands when training is started early. Keep sessions short and fun.
Socialization
Expose your Shih Tzu to various people, pets, and environments during the first year of life. A well-socialized adult Shih Tzu is less likely to develop behavioral problems.
Health and Lifespan
Common Health Issues
While generally healthy, full grown Shih Tzus are prone to specific conditions:
- Brachycephalic Syndrome: Due to their short snouts, breathing difficulties can occur
- Dental Issues: Regular brushing and dental checkups are a must
- Eye Conditions: Watch for signs of dry eye or infections
- Hip Dysplasia: Though rare, it’s worth monitoring
Life Expectancy
With proper care, a Shih Tzu full grown can live anywhere from 10 to 16 years. Good nutrition, regular vet visits, and daily exercise are critical to longevity.
Grooming Needs
Daily Maintenance
Brush their coat daily to avoid mats and tangles. Use a pin brush or a comb suitable for long-haired dogs.
Bathing
Give your dog a bath every 3 to 4 weeks. Use a dog-specific shampoo that maintains skin moisture.
Nail Trimming
Trim their nails every 2 to 3 weeks to prevent overgrowth.
Eye and Ear Cleaning
Wipe their eyes daily with a damp cloth and clean ears weekly to prevent infections.
Feeding a Full Grown Shih Tzu
Dietary Needs
A high-quality diet tailored for small breeds is essential. Look for formulas that support skin, coat, and dental health.
Feeding Schedule
- 2 meals per day for adults
- Avoid overfeeding to prevent obesity
Treats and Snacks
Use treats for training, but monitor portion size to maintain a healthy weight.
Exercise and Play
Activity Level
Although they are not overly energetic, full grown Shih Tzus benefit from daily walks and short play sessions.
Indoor Play
Interactive toys and games like fetch or hide-and-seek help keep them mentally stimulated.
Outdoor Time
Always supervise your Shih Tzu outdoors. Their small size makes them vulnerable to larger animals and extreme weather.
Ideal Living Conditions
- Apartment-Friendly: Their size makes them perfect for small living spaces
- Climate Considerations: Protect from excessive heat or cold due to their flat faces and small frames
- Companionship: They do best in households where someone is home most of the time
Travel and Transport
Thanks to their portable size, full grown Shih Tzus are easy to travel with. Always ensure you have a well-ventilated carrier and pack essentials like food, water, and grooming supplies.
