Shih Tzu Size Range Explained: How Big Does a Shih Tzu Get

Eager to know about the size of a shih tzu? Let’s find out how big does a shih tzu get as they mature.

The Adorable Shih Tzu Breed: A Brief Overview

Shih Tzus are one of the most popular small breeds in the world, known for their adorable appearance and charming personalities. These dogs are classified as toy breeds, originally bred in China as companion pets for royalty. They have a long, flowing coat that comes in various colors such as brown, white, black and gold. They have a broad head with large dark eyes that give them an almost human-like expression. One of the unique characteristics of Shih Tzu is their playful and affectionate personality. They make great companion dogs because of their loyalty to their owners and eagerness to please them. Shih Tzus love to be around people and are very social animals which makes them great for families or apartment living.

The Importance of Understanding Their Size Range

When it comes to getting a new dog, understanding the breed’s size range is crucially important. This is especially true for those who live in apartments or small homes where space can be limited. Shih Tzus are known for being small dogs but there is actually some variation within this breed when it comes to size. Knowing your dog’s expected size range will help you prepare your home accordingly by ensuring you have enough space not just for them but also for any possible accessories such as crates or feeding bowls. Additionally, understanding their size range can help you create an appropriate feeding plan that will ensure they receive sufficient nutrition without overfeeding them which could lead to health complications down the road. Furthermore, if you plan on showing your Shih Tzu in competitions or breeding them later on, understanding the standard weight and height ranges becomes even more important so that you can select compatible mates based on size compatibility. Understanding your shih tzu’s size range is important for various reasons, from ensuring they have enough space to move around, to providing them with appropriate nutrition and selecting compatible partners for breeding. In the following sections, we will explore the average size range of a Shih Tzu, factors that affect their growth and ways to manage their growth.

Average Size Range of Shih Tzu

Shih Tzu is a toy breed dog that is well-known for their long, flowing coat and charming personality. They are a small dog breed, but their size can vary within the breed. On average, adult Shih Tzus stand between 9 and 10.5 inches tall at the shoulder and weigh between 9 and 16 pounds. However, some individuals can be smaller or larger than this range. It’s important to note that size isn’t everything when it comes to Shih Tzus; their temperament, health, and other traits are just as important. But understanding their size range can help you plan for their care needs appropriately.

Height and Weight Range for Adult Shih Tzus

The height range for adult Shih Tzus is relatively consistent within the breed, with most individuals falling between 9-10.5 inches tall at the shoulder. However, there are always outliers, with some individuals being slightly shorter or taller than this average range. In terms of weight range for adult Shih Tzus (age two years or older), most dogs weigh between 9-16 pounds (4-7 kg). The ideal weight will depend on your individual dog’s structure and overall health status; consult with your veterinarian if you have concerns about your pet’s weight.

Comparison to Other Small Dog Breeds

When it comes to other small dog breeds like Chihuahuas or Pomeranians, Shih Tzus fall in a similar size range overall. However, they do tend to be heavier than these breeds due to their muscular build underneath all that fur! As far as height goes, some of these breeds may be slightly taller or shorter than the average Shih Tzu depending on individual variation within each breed. It’s always important to consider any breed-specific health concerns as well when comparing different dog breeds. For example, Shih Tzus are prone to certain eye and respiratory issues that may not be as common in other small dog breeds. However, with proper care and attention from their owners, Shih Tzus can live happy, healthy lives regardless of their size.


Understanding the average size range of Shih Tzus can help you plan for their care needs appropriately. While individual variation exists within the breed, most adult Shih Tzus stand between 9-10.5 inches tall at the shoulder and weigh between 9-16 pounds. Compared to other small dog breeds like Chihuahuas or Pomeranians, they fall in a similar size range overall but tend to be heavier due to their muscular build. By keeping an eye on your pet’s weight and ensuring they receive proper veterinary care throughout their life, you can help them maintain optimal health regardless of their size.

Factors That Affect Size

Genetics and Breeding: Picking the Right Parents Can Make All the Difference

When it comes to determining a Shih Tzu’s adult size, genetics plays a significant role. The size of the parents can give you a general idea of how big your pup will eventually get. If both parents are on the smaller side, it is likely that your Shih Tzu will be small as well. However, if one parent is significantly larger than the other, there may be variation in their offspring. Breeding also plays a role in determining size, as certain breeding practices can increase or decrease the likelihood of a Shih Tzu being larger or smaller. Breeders who purposely breed for smaller sizes may inadvertently create health problems in their puppies due to excessive down-sizing. It is important to do research on potential breeders before purchasing a Shih Tzu puppy to ensure that they adhere to responsible breeding practices and strive for healthy puppies rather than just desirable physical traits.

Nutrition and Exercise: What You Feed Your Shih Tzu Matters

The diet and exercise routine of a Shih Tzu can greatly impact their growth and overall size. Proper nutrition is essential for healthy growth, especially during puppyhood when they are rapidly developing. It is recommended to feed high-quality dog food that meets all nutritional requirements and avoid overfeeding treats or table scraps. Maintaining an appropriate weight is crucial for preventing obesity-related health problems that could affect growth. Regular exercise is also important for maintaining optimal health and muscle development in growing pups. A daily walk or playtime can help burn calories and prevent excessive weight gain.

Health Issues That Can Affect Growth: Identifying Potential Problems Early

Certain health issues can impact a Shih Tzu’s growth rate such as congenital heart defects or orthopedic conditions like hip dysplasia. These issues may require medical treatment and can affect the overall size of the dog. It is important to schedule regular vet check-ups to identify any potential health problems that could affect growth early on. Catching and treating these issues early can prevent long-term complications and ensure optimal growth. In some cases, illness or a lack of proper nutrition during puppyhood can also stunt a Shih Tzu’s growth. Proper care and attention during critical development stages are essential for ensuring that your pup reaches their full size potential.

Conclusion: Understanding the Factors That Affect Your Shih Tzu’s Size

Understanding the factors that impact a Shih Tzu’s size can help you make informed decisions about their care and ensure they reach their full size potential. Genetics, breeding, nutrition, exercise, and health all play vital roles in determining how big your pup will eventually get. By providing proper care and attention throughout their life stages, you can help your beloved pet live a healthy life full of love and companionship.

Understanding the Growth Stages of a Shih Tzu

A Shih Tzu’s growth can be divided into three main stages: prenatal development, early puppyhood growth stages, and teenage growth spurts. Each stage has its unique characteristics and potential challenges. Understanding these stages can help you monitor your puppy’s growth more closely and identify any issues that may arise.

Prenatal Development

The prenatal development stage begins when your Shih Tzu is still in their mother’s womb. During this time, the puppy will grow rapidly as they develop essential organs and body systems. The quality of nutrition that the mother receives during her pregnancy plays a crucial role in determining the overall health of her puppies. It’s essential to ensure that pregnant Shih Tzus receive proper nutrition, including adequate protein, vitamins, and minerals. Neglecting nutrition during this phase can result in low birth weight or malnutrition for the puppies.

Early Puppyhood Growth Stages

Once born, a Shih Tzu will go through significant physical changes during the first few weeks of life. At this stage, puppies need plenty of rest to support their rapid growth rate. They also require frequent feeding to maintain healthy weight gain. At around three weeks old, you’ll start seeing small changes such as eyes opening up, increased mobility due to better coordination and balance control from stronger hind legs muscle development. By six weeks old teeth begin coming in which allows them to eat solid foods while they continue nursing until transitioned by 8-12 weeks old for complete weaning from milk from their mother.

Teenage Growth Spurts

Around 6 months old is when teenage growth spurts occur where a considerable amount of height and weight gains take place over just a few months. During these fast-growth periods ensure their diet continues with adequate protein and nutrients to support their growth while avoiding overfeeding to prevent obesity. These rapid growth spurts can place additional stress on a Shih Tzu’s body, making them more susceptible to fractures or other injuries. It’s essential to monitor your puppy’s activity levels during this phase and limit high-impact activities that could result in injury. Understanding the unique characteristics of each growth stage can help you identify any issues that may arise early on and provide the necessary care for your Shih Tzu. With proper nutrition, exercise, and regular veterinary check-ups, you can ensure that your puppy grows into a healthy adult dog.

How to Estimate Your Shih Tzu’s Adult Size:

Observing The Parents’ Size And Weight:

One of the most effective ways to estimate your Shih Tzu’s adult size is by observing the size and weight of their parents. This will give you a good idea of how large or small your puppy may grow up to be. If both parents are within the average range for the breed, there is a high likelihood that their offspring will also fall within that range. It is important to note that genetics play a significant role in determining a dog’s size, so if either parent falls outside of the average range, it may be more difficult to accurately predict your puppy’s ultimate size. It is also important to consider any potential genetic health issues that may affect growth and development.

Measuring Your Puppy’s Height And Weight At Different Stages Of Development:

Another way to estimate your Shih Tzu’s adult size is by monitoring their height and weight at different stages of development. This can give you insight into whether they are growing at an appropriate rate and if they are on track to reach their full potential size. For example, measuring your puppy’s height when they are around 4-6 months old can give you an idea of how tall they may ultimately grow. Similarly, tracking their weight gain over time can help you determine if they are at a healthy weight for their age and breed. Keep in mind that every puppy grows at their own pace, so it is important not to compare your puppy’s growth too closely with others in their litter or age group. Instead, focus on monitoring their individual progress and consult with your veterinarian if you have any concerns about their growth or development.

Pro Tip:

Take pictures of your Shih Tzu as they grow up! This will not only serve as a precious keepsake but also allow you to visually track their growth progress and compare photos side by side.


Estimating your Shih Tzu’s adult size can be difficult, but observing their parents’ size and weight and monitoring their growth at different stages can provide valuable insight. Remember to consult with your veterinarian if you have any concerns about your puppy’s growth or development.

Tips for Managing Your Shih Tzu’s Growth

Feeding a balanced diet with proper nutrients

One of the most important factors in managing your Shih Tzu’s growth is feeding them a balanced diet with the proper nutrients. A diet that is lacking in essential vitamins and minerals can lead to stunted growth or health problems down the road. It’s important to choose a high-quality dog food that is formulated specifically for small breeds like the Shih Tzu. Look for a food that lists real meats as its first few ingredients, rather than fillers like corn or wheat. Additionally, you may want to consider adding supplements to your dog’s diet. Omega-3 fatty acids and glucosamine are both particularly beneficial for dogs’ joint health, which can be especially important for small-breed dogs like the Shih Tzu who are prone to orthopedic issues.

Providing regular exercise opportunities

Proper exercise is also essential for managing your Shih Tzu’s growth. While they don’t require as much exercise as larger breeds, they still need daily opportunities to burn off excess energy and stay healthy. A daily walk around the neighborhood or playtime in a fenced-in yard can provide enough exercise for most Shih Tzus. It’s also important to provide mental stimulation through interactive toys and games. Puzzle toys or treat-dispensing toys can keep your dog entertained while also providing an opportunity for physical activity.

Regular veterinary check-ups

Regular veterinary check-ups are crucial for monitoring your Shih Tzu’s growth and ensuring their overall health and well-being. Your vet will be able to track your dog’s growth progress over time and identify any potential health problems early on. During these visits, you should discuss any concerns you have about your dog’s growth or behavior with your vet. They can offer advice and guidance on managing your dog’s growth and help you create a plan for keeping them healthy throughout their life.

The Importance of Proper Growth Management

Managing your Shih Tzu’s growth is essential for ensuring their overall health and well-being. By feeding them a balanced diet with proper nutrients, providing regular exercise opportunities, and scheduling regular veterinary check-ups, you can help ensure that your Shih Tzu grows up to be happy, healthy, and well-adjusted. If you have any concerns about your Shih Tzu’s growth or behavior, don’t hesitate to speak with your vet. They can provide valuable insight and support as you navigate the process of raising your beloved companion. With proper care and attention, your Shih Tzu will flourish into an adult dog that’s as healthy as they are adorable!
