Why is my Shih Tzu puppy so hyper?

One of the main contributors to hyperactivity in Shih Tzu puppies is a lack of sufficient physical exercise.
These puppies may become agitated and annoyed without appropriate and consistent physical outlets.
Other potential causes of hyperactivity in Shih Tzus include an imbalanced diet, boredom, hereditary factors, and their innate sprightly and active temperament.
To subdue hyperactivity in a Shih Tzu, owners can employ positive reinforcement techniques such as rewarding the dog with treats or toys when it behaves in a desired manner.
Additionally, it’s essential to ensure that the pup gets enough physical activity to expend its surplus energy.
Enrolling the puppy in training classes can also aid in managing any hyperactivity issues.

Health issues can also contribute to aggression in Shih Tzus, so it is essential to rule out any underlying medical conditions or hidden injuries with a visit to the vet before determining that your pup is excessively aggressive.
The critical time for a Shih Tzu’s behavioral development occurs during the 6th week.
If socialization is not established during this period, it can be more challenging to prevent aggressive behaviour from arising.
Fostering positive associations between the puppy and other individuals and animals can help mitigate aggressive behavior.
Additionally, providing consistent training and guidance from an early age can aid in preventing aggression in Shih Tzus.
Are Shih Tzu Adults & Old Calmer Than Puppies?
Shih Tzu, as they mature, tend to exhibit a more subdued demeanour than their exuberant puppyhood.
A Shih Tzu’s boisterousness can be tamed with suitable training when they reach half a year to a year old.
As they advance in years, they become more affectionate and well-mannered.
Though they may not possess the physical attributes of a guard dog, their attentiveness and activity level render them excellent watchdogs.
Are Puppies Of Other Breeds Calmer Than Shih Tzu?
Shih Tzus are celebrated for their amiable, gregarious, and blithesome natures.
Though, they can be high-strung and require great care and attention.
They tend to interact well with other canines and have an amiable energy level.
Their sagacity determines their temperament, rendering them captivating and pleasant. Furthermore, they tend to shed less fur than many other breeds.
It can be challenging to determine whether puppies of other breeds possess a more composed disposition than Shih Tzus, considering the diversity and singularity of each canine’s temperament.
Nonetheless, it bears mentioning that certain species may boast a reputation of being more calm and equable and thus may be considered more serene than Shih Tzus on average.
Factors such as the breed’s size, energy level, and intended purpose can also play a critical role in determining the composure of a puppy.
For instance, selectively bred for hunting or herding species may have higher energy levels.
In contrast, breeds bred for companionship may have more relaxed temperaments.
It’s also crucial to remember that environmental and training factors can also shape the behaviour and character of a puppy.
Thus, it’s paramount to research the breed and the individual puppy’s personality before deciding and seeking guidance from a veterinarian or professional dog trainer.
At what age do Shih Tzu puppies go into heat?
Shih Tzu puppies commonly attain sexual maturity between the ages of 4 to 7 months, as per various sources.
During this phase, female Shih Tzus undergo physiological changes such as vulval inflammation and the emergence of slight amounts of blood.
The average duration of a Shih Tzu’s oestrous cycle is around 23 days or roughly 2 to 4 weeks, and it usually happens twice a year.
However, it’s worth noting that the timing and duration of an oestrous cycle can vary from dog to dog and can be affected by various factors such as nutrition, exercise, and overall health.
It is of utmost importance to acquire the expert advice of a veterinarian to ensure your beloved dog’s optimal health and welfare and garner a thorough comprehension of the most appropriate means of providing care and nurturing during this important stage of their life.
When do Shih Tzu puppies stop biting?
Shih Tzu puppies generally cease biting by the time they reach 1 year old.
This is because their teething process typically concludes at around 10 months when all their adult teeth have emerged.
The teething process can be uncomfortable for puppies, and they may resort to biting and nipping to relieve discomfort and investigate their surroundings.
To discourage biting, owners need to begin training their Shih Tzu puppy from an early age.
Training methods that can be effective include:
- Redirecting the puppy’s focus away from biting.
- Providing them with chew toys.
- Reinforcing positive behaviour with rewards such as treats or praise.
Training should also be supported throughout the puppy’s life to maintain good behaviour and prevent any biting habits from returning.
It’s also important to understand that Shih Tzu puppies are naturally curious and like to explore the environment with their mouths.
So, it’s essential to be patient and consistent in training.
At what age do Shih Tzu puppies stop growing?
Shih Tzu puppies will attain their full adult stature around 6 to 8 months.
Nevertheless, it’s crucial to remember that they may continue to put on weight until they reach the age of 2.
The dimension and weight of a fully grown Shih Tzu can be contingent on the size of its progenitors.
Still, on average, a mature, healthy Shih Tzu starting at 1 year of age, weighs between 9 to 16 pounds.
It’s also worth mentioning that the American Kennel Club (AKC) breed standard for Shih Tzu states that the optimal weight is between 9 and 16 pounds, with the range being between 9 and 18 pounds.
The height at the withers (the highest point of the shoulder blades) should be between 8.5 and 11 inches.
It’s essential to remember that while Shih Tzu is considered a small breed, there can be variations in size and weight.
It’s paramount to seek the advice of a veterinarian to ensure that your pet is at optimal weight.
Final thoughts

During this time, they may become less active and calmer.
However, every dog is unique; some may take longer to reach this stage.
Proper training and socialization can also play a significant role in a Shih Tzu’s behaviour and temperament.
Owners should work with a reputable breeder or trainer to ensure their Shih Tzu receives the proper guidance and care to reach its full potential.
