Introduction: Understanding Shih Tzu Puppies Growth
Watching your Shih Tzu puppies grow is one of the most rewarding experiences as a dog owner. From tiny newborns to playful one-year-olds, every stage brings exciting physical and behavioral milestones. Understanding these growth stages helps you provide proper care, nutrition, and training to ensure your puppy thrives.
In this guide, we’ll explore 7 key growth stages of Shih Tzu puppies, including their physical development, behavioral changes, training tips, and how to choose a responsible Shih Tzu breeder.
1. Birth to 2 Weeks: The Neonatal Stage
The first two weeks of life are critical for Shih Tzu puppies.
Physical Milestones:
- Puppies are born blind, deaf, and dependent on their mother.
- Eyes and ears remain closed; puppies rely on smell and touch.
- Sleep and nursing dominate this stage.
Behavioral Milestones:
- Limited movement—crawling toward warmth and food.
- Begin to vocalize with tiny squeaks to communicate hunger or discomfort.
Proper care at this stage includes keeping the puppies warm, ensuring frequent nursing, and monitoring weight gain.
2. 2 to 4 Weeks: The Transitional Stage
During this stage, Shih Tzu puppies begin to experience the world around them.
Physical Milestones:
- Eyes and ears start to open.
- Puppies begin to stand and walk unsteadily.
- Teeth start developing.
Behavioral Milestones:
- Begin to interact with littermates.
- Start playful behavior such as gentle biting and pawing.
This is the first stage of socialization. Gentle handling helps puppies adjust to human touch.
3. 4 to 8 Weeks: The Socialization Stage
Socialization is critical for Shih Tzu puppies to grow into confident adults.
Physical Milestones:
- Continued growth and increased coordination.
- First full set of deciduous (baby) teeth by 6–7 weeks.
Behavioral Milestones:
- Play becomes more interactive and purposeful.
- Start learning bite inhibition and social cues from littermates.
- Explore their environment more actively.
Early exposure to gentle handling, sounds, and different surfaces supports healthy socialization.
4. 8 to 12 Weeks: Weaning and Independence
At this stage, Shih Tzu puppies begin transitioning from mother’s milk to solid food.
Physical Milestones:
- Rapid growth and development.
- Teeth fully in, supporting solid food.
Behavioral Milestones:
- Increased curiosity and exploration.
- Beginning of housetraining and responding to basic commands.
- Strong attachment to humans develops.
This stage is ideal for basic obedience training and establishing a routine for feeding, sleeping, and elimination.
5. 3 to 6 Months: The Juvenile Stage
Your Shih Tzu puppy is now a confident little explorer.
Physical Milestones:
- Growth continues steadily but slows compared to the first few months.
- Adult teeth begin to replace baby teeth.
- Muscles and coordination improve.
Behavioral Milestones:
- Begin testing boundaries and independence.
- Increased playfulness and energy.
- Social skills sharpen through interaction with people and other pets.
Consistent training and positive reinforcement during this stage help prevent undesirable behaviors.
6. 6 to 9 Months: The Adolescence Stage
Adolescence is a critical time for Shih Tzu puppies as they refine their personality and habits.
Physical Milestones:
- Approaching full adult size (small breed, but growth continues slightly).
- Coat may begin changing texture or developing fuller color.
Behavioral Milestones:
- Can display selective hearing or stubbornness.
- Energy levels are high; plenty of exercise and mental stimulation is essential.
- Social maturity starts forming—may be wary of strangers if not properly socialized.
Patience and consistent guidance during adolescence help shape a well-behaved adult dog.
7. 9 to 12 Months: The Young Adult Stage
By one year, Shih Tzu puppies reach most of their adult size and begin displaying adult temperament.
Physical Milestones:
- Fully developed adult teeth and near-final size.
- Coat and grooming needs stabilize.
Behavioral Milestones:
- Established personality and habits.
- Can be trained for advanced commands and tricks.
- Energy remains moderate; enjoys play and companionship.
At this stage, you can transition to adult food, continue socialization, and refine training for a well-rounded adult dog.
Training and Socialization Tips for Shih Tzu Puppies
Proper training and socialization throughout each stage ensures a confident, well-behaved Shih Tzu adult.
Key Tips:
- Use positive reinforcement with treats, praise, and play.
- Keep training sessions short and consistent.
- Introduce new people, pets, and experiences gradually.
- Start housetraining early and maintain routine.
Regular mental and physical stimulation keeps Shih Tzu puppies happy and prevents behavioral problems.

- Health screenings for parents (eyes, hips, heart).
- Puppies raised in a loving home environment.

Selecting a reputable breeder ensures your Shih Tzu puppy gets the best start in life.
