Yorkshire Terrier Growth Chart: How big do Yorkies get?

Fully grown Purebred Yorkies get around 7 to 8 inches (18- 20.5cm) tall and weigh anywhere between 4 to 7 pounds (1.75 and 3.20kg). The exact height and weight of a Yorkie depend on their Genetics, diet, nutrition, exercise, and sleep schedule

Hi, I am Daniela Carrera, a professional dog trainer, and a Yorkie parent for the last 7 years. A lot of Yorkie owners ask me their doubts and questions and one of the most common questions out of them is “How Big will my Yorkie get?“. Owners want to know how much will their Yorkie’s average size be at each phase in their Yorkie’s life.

Therefore, in this detailed guide, I cover each and every detail regarding your Yorkie’s average size, growth, and tips to maintain his or her weight.

Average Size of a Yorkie

When measured from their shoulders to the ground, Yorkies are around 7 to 8 inches (18- 20.5cm) tall.

The length of a Yorkie, which is measured from the base of the neck to the base of the tail, is of equal proportion to their height.

However, the size of Yorkies varies a lot. Even siblings and puppies from the same parent vary greatly in their size and weight. Their size and weight are determined by their genetics, diet, and exercise.

Yorkies are smaller in size as compared to other dog breeds. But, if your Yorkie is smaller than 6.5 inches when he has fully grown, you should consult your Vet. Smaller Yorkies are more prone to various health problems.

In some cases, there are Yorkies which are usually taller. But, if your Yorkie is taller than 8.5 inches, it could be that He or She is not Purebred.

Check out this post for a comparison between the average sizes of a male and a female Yorkie.

Average Weight of a Yorkie

The average weight of Yorkies is 4 to 7 pounds (1.75 and 3.20kg). However, there are purebred Yorkies weighing 9 to 10 pounds as well when due to genetics or their feeding pattern.

If any Yorkie weighs more than 10 pounds, there are chances that a dog of a large breed has been introduced at any point of time in his ancestry.

I have observed Yorkie parents focussing and stressing a lot on their Yorkie’s weight. It’s great to have concern for your dog but do not get too obsessed with maintaining his or her weight.

As long as your Yorkie is in good shape (not overweight), has a decent diet and appetite, and exercises often, you shouldn’t worry too much. Here’s a post on How big can healthy Yorkies grow?

If your Yorkie weighs less than 4 pounds, he or she will be considered underweight and would be called a “Teacup Yorkie. Teacup Yorkies are underweight Yorkies who are prone to many health problems due to their poor breeding practices.

Comparison of Yorkie’s size to other small dog breeds 

Though Yorkies are small dogs, when compared to other small dog breeds, it isn’t the smallest. Two dogs, Chihuahuas (6-9 inches and 2.5-6 lbs ) and Pomeranians (8-11 inches and 3.5-7 lbs) are smaller than Yorkshire Terriers.

You can say that Yorkies are the third smallest dog breeds in the world.

However, according to some British journalist reports, the smallest purebred dog ever recorded was a Yorkshire Terrier named Sylvia who weighed only 4 ounces and 2.5 inches tall.

Yorkie Puppy Growth

Yorkshire Terriers grow rapidly by the 9 to the 10-month mark. After that, the growth in their height and weight decreases, and by the time a Yorkie celebrates his first birthday, he or she has grown up to the full potential.

Newborn Yorkies weigh anywhere between 2 and 5 pounds. Gradually, a Yorkie gains around 2 ounces each week. When a Yorkie turns 18 months old, his weight is typically triple of his birth weight.

At the 9 month mark, your puppy may seem to look underweight and a little weak. This is completely normal. After that phase, a puppy’s body develops its muscles and he gets taller as well. At the 12 month mark, your Yorkie will look completely fit and healthy.

Whether a Yorkie looks too skinny or overweight, you should always look to feed proper diet and nutrition to him and make sure he or she gets ample exercise and training. Here are the food items that both you and your Yorkie can eat.

How big will your Yorkie puppy get? 

Are you curious about How big will your Yorkie puppy get once he reaches adulthood?

This is the formula that you can use to accurately predict your Yorkie’s weight once he reaches 18 months.

Weight of Adult Yorkie (18 months) = Weight of a Yorkie at Eight Weeks (in ounces) x 3 

For example, if your puppy weighs 3.5 ounces at the age of 8 weeks, he will weigh approximately 10.5 ounces at his full size.

If you didn’t calculate your puppy’s weight when he was 8 weeks old, don’t worry as I have another solution for all the Yorkie owners. I have developed this Yorkie growth chart after asking 20 Yorkie owners to input their dog’s weight at various phases in their lives.

If you know any other Yorkie owner who might need this, feel free to share it.

How to know if your Yorkie has a healthy weight? 

If you have some doubts about whether your Yorkie has a healthy weight or not, you can do a physical assessment of your dog to clear your doubts.

Here is how you can inspect a Yorkie’s body mass ratio:

  • Look down at your dog from behind. Now, move your eyes from his ribcage down to his waist. If you observe that his waists move inward when you move your eyes down, then his body mass ratio is fine.
  • Place your hands on the sides of your dog on the ribcage. Try to touch each and every rib. If you are able to feel each rib without seeing it, it usually means that your Yorkie has a healthy weight. If you can both see and feel each rib, your Yorkie can be underweight.
  • Try and run down your fingers through your Yorkie’s spine and try to feel his pelvic bone. If your dog has a lot of hair, it could be a challenging task for you. If you are easily able to feel his pelvic bone and vertebrae, it means that your Yorkie is underweight. If you can feel a thin layer of fat between his bone and skin, it means that he or she is of a healthy weight.

If you feel that your Yorkie is too big or too small, you should talk to your Vet as he may be better able to consult you. Most probably, too small Yorkies fall under the category of Teacup Yorkies.

But what if your Yorkie is too large or overweight?

Is your Yorkie too Large or Overweight? 

overweight yorkie

If your Yorkie weighs more than 10 pounds but he looks healthy, has a good exercise and training schedule and your Vet isn’t concerned, there is absolutely no reason to worry for you as well.

There are many Yorkies who have heavier bones which is the reason for them being overweight. If your Yorkie is taller, he or she will weigh more as well.

In many cases, I have observed that Yorkies above 10 pounds are completely healthy and active and they don’t need to lose weight as well.

Is your Yorkie overweight? 

If your dog consumes more calories than he needs to carry in his daily routine, he will gain weight. Yorkies can quickly gain weight if they are eating too much packaged food and not exercising enough or properly.

The bad news is that it gets very challenging and difficult for a Yorkie to lose weight once he starts gaining weight.

Obesity causes certain health problems in Yorkshire Terriers and excess fat puts more pressure on his heart. Obesity can also cause kidney disorders, respiratory disorders, skin problems, shorter lifespans, high blood pressure, and various other health problems. 

Tips to help a Yorkie lose weight 

If you feel that your Yorkie is overweight and your Vet agrees to it, then there are some ways to help your dog shed some of his body fat. You may also need to change his lifestyle and routine which is slow but if you stay consistent with it, it can save your Yorkie’s life.

  • You will need to change your dog’s calorie intake. Ask your Vet or Nutritionist to create a diet chart with lower calorie intake. You will need to switch to lower-calorie dog food. Whenever you try to change his food, give your Yorkie a bowl that contains half of the old food and half of the new food for two weeks so that his stomach and body can gradually process that change.
  • If your Yorkie doesn’t have a proper exercise schedule, take him to walks outside twice a day and play games like fetch and tug of war with him. A good diet and plenty of exercises go a long way in improving your dog’s health and lifestyle.

When do Yorkies stop growing? 

when do yorkies stop growing

Just like other dogs, Yorkies are born small and they grow rapidly. Yorkies also have several development phases in their life from puppyhood to adulthood.

First Phase: Birth to 2 Weeks 

During the first two weeks in a Yorkie’s life, he needs the most care as he’s helpless and dependent on his mother/owner. At birth, Yorkies weigh between 2 to 5 ounces.

In this first phase, puppies are sleeping 90% of the time and can’t survive without their mother.

Second Phase: 2 weeks to 8 weeks 

After 2nd week, a Yorkie puppy starts to crawl and explore the world around him. At first, they find it challenging to crawl too far, but soon with practice, they are able to crawl to longer distances.

This is the phase where siblings start to play with each other and can be observed tumbling over each other.

Puppies will start to taste liquid on their own and you can slowly start to introduce solid foods as well. There are breeders who try to get puppies completely off their mother’s milk by the time puppies turn 8 weeks old. However, some breeders wait until 12 weeks by the time Yorkie puppies don’t drink mother’s milk too often.

You can start crate training and potty training your Yorkie during this phase.

Third phase: 8 weeks to 6 months 

You will observe your puppy developing a lot during this phase and you will definitely enjoy this phase where you will observe your Yorkie puppy growing bigger in front of your eyes.

Puppies will play a lot, eat a lot and sleep a lot during this phase. He will nip and bite your hands. He will lick you a lot.

This is the phase where a puppy builds his confidence, temperament, and character. As his owner, you should try to socialize your puppy with other dogs and kids as much as you can. Your puppy will also start to develop certain behavioral problems during the third phase. Some of them are excessive barking and Separation anxiety.

Feed them with a proper diet, maintain an exercise and training schedule, and fill this phase with experiences that build your puppy’s personality.

Fourth Phase: 6 months to 2 years 

A Yorkshire Terrier’s personality and character start to take shape during the fourth phase. You must continue to socialize your Yorkie with the world.

Start to act like the alpha male of the pack or else your teenage Yorkie will start to show dominance and think of himself as the leader of the pack. Stimulate your dog mentally and physically as much as you can on a consistent basis. A tired dog is a good dog.

As I said, your Yorkie’s physical growth will slow down when he or she turns 9 months old.

Somewhere during this phase, your Yorkie will reach sexual maturity, and females will go into heat.

Fifth Phase: 2 years to 10 years

The growth phase is over by 2 years and his weight won’t gain or lose much at this point. Most of his personality must have been built and his body must have been habitual of the exercises and training.

Due to their natural instincts, your Yorkie will roam around your house and guard everything. If he spots any rat or squirrel in your background, his natural chasing instincts will kick in and he will run like a roadrunner.

Sixth phase: 10 years +

This phase is equivalent to senior citizens in human beings. Yorkies get old and start suffering from various health problems.

Their diet and appetite decrease and they could suffer from arthritis. During this phase in their life, they would need someone to look after them and take extra care.

Your Yorkie will be sleeping much longer and won’t like to play or go on walks often. Talk to your Vet if he or she needs any additional supplements during this time.

How does Genetics affect the size of Yorkies? 

You can look at the mother and father to guess how tall or heavy your puppy would be when he gets older. But, the inherited genes go much deeper into older generations as well.

Just like in humans, sometimes, newborns look identical to their grandfathers, Yorkies also skip a generation and look identical in size and color to their elder generations.

Generally speaking, the size of a Yorkie depends on the size of his or her father. If you are getting your Yorkie from a breeder, make sure that the breeders know everything about the family history and bloodline of the puppies.


I hope now you know everything regarding Yorkie’s size and different development stages in his life. Sometimes, there are dogs that may not fall in between the common range of size and that’s fine as long as he is healthy, active and eating well.

You can use various methods to measure your Yorkie’s size and act accordingly. If you want your Yorkie to be intelligent and obey your commands, Do check out The Online Dog Trainer by Doggy Dan.
