Yorkies experience rapid growth during their puppyhood. By the time they are 3 months old, you may notice a significant difference in their size compared to when they were born. It’s natural to wonder how much more will a 3-month-old Yorkie grow and what to expect in terms of size and weight.

When do Yorkies Reach Full Size?

Yorkies, like many dog breeds, go through various stages of development as they grow. It’s important to understand the growth timeline of a Yorkie to provide proper care and nutrition throughout their development.

Yorkies typically reach their full size when they are around 1 year old. However, the rate at which Yorkies grow can vary from dog to dog. On average, Yorkies will reach about half of their adult weight by the time they are 6 months old.

At 12 weeks old, a Yorkie puppy can weigh anywhere from 1.5 to 3 pounds, depending on their genetics and diet. By this age, they are still considered puppies and have a lot of growth ahead of them.

As Yorkies continue to grow, their growth rate will slow down. By the time they are 9-12 months old, most Yorkies will have reached their full size and weight. It’s important to monitor their growth during this time to ensure they are developing properly.

When determining if a Yorkie is fully grown, it’s not just about their weight but also their overall appearance. Yorkies are considered adults once they reach their full size and have a mature coat and features.

Remember that every Yorkie is unique, so their growth timeline may vary slightly. Providing them with a balanced diet, regular exercise, and proper care will help them reach their full potential and live a healthy, happy life.

Factors Affecting Yorkie Growth

Yorkie growth is influenced by various factors, including genetics, nutrition, health, and environment. Understanding these factors can help you manage your Yorkie’s growth and development.


Genetics play a significant role in determining how big a Yorkie will grow. The size of the parents can give you an idea of your Yorkie’s potential size as an adult. Yorkies from smaller parents tend to be smaller themselves, while those from larger parents may grow to a larger size.


A balanced diet is essential for proper growth and development in Yorkies. Providing high-quality puppy food with the right balance of nutrients is crucial during the growth stages. Overfeeding or underfeeding can impact your Yorkie’s growth rate and overall health.

Your Yorkie’s overall health plays a vital role in their growth. Regular veterinary check-ups, vaccinations, and parasite prevention are essential for ensuring your Yorkie grows healthy and strong. Health issues or underlying conditions can affect their growth rate.


The environment in which a Yorkie grows up can impact their growth. A safe and stimulating environment with plenty of exercise and socialization can promote healthy growth and development. Adequate playtime and mental stimulation are essential for a Yorkie’s overall well-being.

When does a Yorkie puppy stop growing? Yorkies typically reach their full size between 12 to 18 months of age. By this time, they are considered adults and have stopped growing. The growth rate varies from one Yorkie to another, so it’s essential to monitor your pet’s growth progress regularly.

Feeding Your Growing Yorkie

Proper nutrition is essential for the healthy growth and development of your Yorkie. During the puppy stage, it’s crucial to provide a balanced diet that supports their rapid growth. Yorkies typically reach their full size at around 1 year of age, so it’s important to feed them appropriately at each stage of their development.

As your Yorkie grows, their dietary needs will change. It’s crucial to monitor their weight and adjust their food intake accordingly.

Monitoring Health During Growth

It’s important to monitor the health of your Yorkie as they grow to ensure that they are developing properly. Here are some key points to keep in mind:

  • Provide a balanced diet: A nutritious diet is essential for your Yorkie’s growth and development. Make sure to feed them high-quality food that meets their specific nutritional needs. Avoid overfeeding or feeding too many treats, as this can lead to obesity and other health issues.
  • Exercise and playtime: Regular exercise is important for your Yorkie’s physical and mental well-being. Engage them in playtime and walks to keep them active and healthy. Be mindful not to overexert them, as Yorkies are small dogs with specific exercise requirements.

Exercise Tips for Growing Yorkies

Yorkshire Terrier puppies, like all puppies, go through different growth stages as they develop into adult dogs. It’s important to provide appropriate exercise for your Yorkie at each stage of its growth to support its physical health and development.

1-7 years Adult Maintain a regular exercise routine with daily walks and playtime. Consider agility training to keep your Yorkie mentally stimulated.

When to Consult a Vet

If you notice that your Yorkie is not gaining weight as expected or if there are sudden changes in their growth rate, it’s important to consult a vet. A vet can help determine if there are any underlying health issues that may be affecting your Yorkie’s growth and development. Monitoring how much an 11 week old Yorkie weighs can also give you an indication of their overall health.

Additionally, if your Yorkie is not acting like a puppy anymore, it may be a sign of aging or health concerns. Consulting a vet can help determine if there are any medical issues that need to be addressed. Understanding the different stages of a Yorkie puppy’s growth can also help you know when they are no longer considered a puppy.
