Yorkie growth chart and Yorkshire terrier development stages

Yorkie growth chart and Yorkshire terrier development stages

The growth and development of Yorkshire terrier puppies depend not only on their age but also on the hereditary relations, the number of puppies in the litter and the proper cares and feeding during the first couple of months of life.

In the following article, we have selected products for easy record keeping and weighting scale that makes weight tracking much easier and convenient. You can find the products down in the article.

Yorkie development/ growth stages

The following stages of the Yorkshire terrier development are distinguished by the experts:

  • Еmbryonic ((intrauterine) – lasting 58-65 days
  • Suckling – from birth to 1 -1.5 months
  • Puppies – from 1 -1, 5 till 6 months
  • Youngster – from 6 to 8-10 months
  • Yong dog – from 8-10 months to 2-2.5 years

As a result of many years of research on the higher nervous activity of dogs, four periods in the individual life of Yorkies are distinguished from birth to full maturity.

First period

  • From day 1 to 18 – 21 day of the puppy’s life – the period of predominantly unconditioned reflex adaptation.

Puppies are born helpless, with closed eyes and ear canals, not adapted to independent life. They are under constant maternal supervision and care and are only able to crawl and suck their mother’s milk. Yorkie development stages

The eyes will usually open from the 8 days of birth and ear canals from day 5. The eyes and the ear canals open completely to the 14 -1 5 day of the life of the young Yorkies.

However, after this, puppies are able to distinguish only bright moving objects and only gradually become fully sighted during the first days.

In the first days of life, puppies are not able to relief themselves from urine and feces and do this with the help of the mother who licks and massages them in order to activate the contraction of the corresponding muscles.

During this period, baby Yorkies spent most of the day sleeping while their body weight including the brain increases massively.

They start to develop the sensory organs like olfactory, taste, temperature detection and thermoregulation and vestibular system.

Second period

  • From day 18 – 21 to 30 – 35 day – the period of primary conditioned reflex adaptation. The intensive increase of body weight including the brain continues daily.

Puppies gain the ability to develop continued reflexes not only to food stimulants but also some defensive abilities. But their formation is still very slow and a lot of exercises are required.

Third period

  • From week 5 – 6 to 8-12 week – the most important period for educational training. The intensive body weight gain gradually slows down.

By that time the Yorkshire terrier babies can already live without their mother’s supervision and are able to eat food different from her milk.Yorkie development

An important part of this period is the ability to quickly produce conditioned reflexes. Puppies show intense activity, getting acquainted with the surrounding environment.

They acquire what we call it the “exploring” reflex, which is fully expressed from 1.5 to 3 – 4 months. It makes them so curious that they want to touch, sniff, see and taste everything around them.

While in the second period of development Yorkies only notice external subjects (like people, animals, objects, etc), here already in the third period they are now ready to approach, sniff and lick them in order to examine them.

During this time, the daily walks outside are very important not only for the proper physical development but also for gaining enough life experience.

Experts suggest that for best result it is good to daily change the route of the walks. That way the little puppy will see different objects, will hear different noises and will surely see new people and animals. That is how a Yorkie should be properly socialized with the external world.

Fourth period

  • From month 3 – 4 to 6 – 7 months – the period of formation of typological features of the nervous system.

Important! The common approach to education and training of Yorkie puppies without taking into account their individual characteristics will not only be ineffective but also harmful.Yorkie growth

We can say that before this period all puppies have almost the same behavior and temper. They willingly and actively communicate with people, including strangers, love to play with them, get easily excited, and show all those complex impulses of a positive and active communication.

Entering into the fourth period, Yorkies tend to be much more cautious showing defensive reactions to various external objects. They are much more restrained with strangers and unknown objects showing a real mature behavior.

The joyful games are sometimes replaced with observing from a distance and even hiding if a potential “danger” is around.

By the third and fourth months, Yorkshire terrier puppies can be already different from each other and that is the time when they acquire their individual behavioral qualities. With the age, those qualities become more expressed and diverse.

By the end of the 4th period, the individual behavioral traits are already well expressed within the Yorkies. Therefore people must take into consideration these individual traits while taking training lessons and teaching new things.

Each doggie needs a different approach and method of learning depending on the mood, character and learning abilities.

I know from my own experience that teaching and training a dog is not a simple task. Not everyone knows how to approach a dog and make it understand your commands.

That is why I always share my priceless experience with the dog training course of Adrienne Farricelli. Years ago when I started dealing with dogs I was so desperate because I could never manage to make them understand my commands, potty train them and teach them how to behave with strangers.

That all changed one day when I was reading in a blog so many happy parents sharing their experience with Adrienne.  So I decided to try and years later I can honestly say that it was one of the best decisions in my life.

Now I communicate with my dogs just like I do with people. No matter what breed, I know how to approach different dog personalities and that makes teaching so simple and pleasant. I always say – a well-trained dog is a happy dog. So if I can give you one advice today when your Yorkie puppy is still small, get Adrienne’s course and I am telling you your future coexistence will be a fairy tale!

Yorkie growing notes

The first year of life is the most important period of development of the puppy’s body. The mistakes that will be made during this period will significantly affect the further health of the dog.

In the initial period of the puppy’s life, special attention must be paid to the diet, lifestyle and cares of the Yorkshire terrier.

Let’s make it clear and say that the processes of growth and development of each puppy during the first year are different.Yorkie growing

For example, a Yorkie puppy at the age of one month is possible to have a large head, an extended body and short paws with floppy ears. By the third month, the ears of the terrier should take a standing position, but this does not happen with all the doggies.

At about six months the Yorkshire terrier’s chest and body should be already formed. The limbs continue to grow and form until the tenth month.

The baby teeth usually change with permanent between the fourth and the seventh month. If all the baby teeth are not changed by the eighth month, you should consider a visit to a vet clinic and remove them with partial anesthesia.

Once again, we want to point that puppies from different litters develop individually, therefore all the information above refers to the average standards of the Yorkshire terrier breed.

When do Yorkies stop growing?

Yorkie stop growing

Speaking of the weight of the puppies, we want to be truly honest with you and inform you that there are no exact calculation formulas to predict how big or small a particular doggie will be.

We know that there are many sources where you can read a lot of information and methods to predict the weight by calculating them with the age, but please consider that those are only approximate values.

Reaching one year, you can already have an idea of what your Yorkie will look like as after this age the weight varies insignificantly to a greater or lesser extent.

How to calculate the possible weight of a Yorkshire terrier

So during the years, we tried to estimate potential weight a puppy will get as an adult and here is the formula that we came up with a lot of tries and consultation with experts:

*Please note that those are only approximate values. Use them only as a base. They may vary as we already said each puppy is independent and its progress is strongly individual.

At the age of two months

The weight of a two-month-old puppy you multiply (x) by 3 and add (+) 0.44 lbs (0.2 kg) = possible weight of an adult Yorkie

Or showing an example:

Let’s say the puppy weights 1.1 lbs (0.5 kg) at the age of two months

1.1 lbs (0.5 kg) * 3 = 3.3 lbs (1.5 kg) + 0.44 lbs (0.2 kg) = 3.74 lbs (1.7 kg) the possible weight of the particular Yorkie puppy as an adult

At the age of three months

The weight of a three-month-old puppy you multiply (x) by 2 and add (+) 0.22 lbs (0.1 kg) = possible weight of an adult Yorkie

Or showing an example:

Let’s assume the puppy weights 1.76 lbs (0.8 kg) at the age of three months

1.76 lbs (0.8 kg) * 2 = 3.52 lbs (1.6 kg) + 0.22 lbs (0.1 kg) = 3.74 lbs (1.7 kg) the possible weight of a grown-up Yorkie

At the age of six months

To the weight of the six months old pup, you must add (+) 1.1 lbs (0.5 kg) = the possible weight of a grown-up Yorkie

And here is the example:

Assuming that the Yorkie pup weights 2.2 lbs (1kg) at the age of six months

2.2 lbs (1kg) plus (+) 1.1 lbs (0.5 kg) = 3.3 lbs (1.5 kg) the possible weight of a grown up Yorkie

Products for easy measuring and weight record keeping

When we took our Zuzi from the breeder she was almost three months. He told us to constanly keep track on her weight to se how is she developing.

It is really important during the first couple of months. Even now when she is 2 years old we still use the scale on time to time.

It says a lot about her overall state of health. If we see some weight loss it is a sign of a health issue.

On the other hand, if we see that she is gaining too much weight, it might be a sign that we need to take her out for longer walks or change the food.

It is especially important during the winter when we have much shorter walks due to the cold weather.

The weight mainly depends on the following factors:

  • Proper feeding – you must take into consideration the breeder or vet prescriptions. Small puppies need special food and vitamins depending on the diet they had right after their birth.
  • Timing – again according to the breeder and vet prescriptions you need to feed your little baby at exact time intervals.
  • It is necessary to control the amount of food – the puppy should not be overfed or starve.

Yorkie growth chart

It is always interesting to observe how your beloved puppy is developing and growing. Below is a chart that you can use to determine the approximate weight he will be when full grown.

*Please note that those are only approximate values. Use them only as a base. They may vary as we already said each puppy is independent and its progress is strongly individual.

Here is how to use the chart:

  1. Find out the current age (in weeks) of your Yorkie on the left of the table
  2. Move from the left to the right to find his current weight (oz.). Be careful and keep the same raw while moving.
  3. After you find the current weight in the same row as the age, swipe down your finger to the end of the column and there you will find the expected weight of your Yorkie when he is fully grown up.

Approximate indicators according to the age of the Yorkshire terrier puppy.

Below we have summarized the information of different sources where you can find the approximate weight according to the age of a Yorkie puppy.

Those are just average values but they will help you to know how your puppy is developing according to them and what to expect as the time is passing.

Again, those are average values that are most likely to vary between each and every Yorkshire terrier.

Puppy birth weight:

From 0.198 lbs. (0.09 kg) to 0.286 lbs (0.13kg)

First month:

From 0.573 lbs. (0.26 kg) to 1.06 lbs (0.48 kg)

Second month (8 weeks):

From 0.992lbs (0.45 kg) to 2.11 lbs (0.96 kg)

Third month:

From 1.5 lbs (0.68 kg) to 2.95 lbs (1.34 kg)

Fourth month:

From 1.94 lbs (0.88 kg) to 3.7 lbs (1.68 kg)

Fifth month:

From 2.31 lbs (1.05 kg) to 4.5 lbs (2.04 kg)

Sixth month:

From 2.5 lbs. (1.14 kg) to 5.4 lbs (2.45 kg)

One year and six months:

From 3 lbs (1.36 kg) to 7 lbs (3.10 kg)

Standard dimensions of male and female Yorkies


The standards of the breed do not specify a height which a Yorkie should fit in. However, in most of the cases, they are between 6 inches and 9.5 Inches and this is when measured from the floor to the top of the shoulders.Yorkie standart dimensions


Speaking of the weight, the standard of AKC has no minimum weight anymore, but rather a maximum of 7 lbs (3.17 kg).

Remember that the standards do not mean much and you should not be surprised if your doggie weighs more or is higher of what we have mentioned before.

There is a number of reasons that he might not fit in the usual dimensions but the main one is his hereditary relations.

    If both parent ears up ..puppy will have ears up too .

    • Gillian Posted February 21, 2018 6:38 am

      Not necessarily! One or two of the grandparents could upright ears. It depends on a recessive gene coming through.

    • Angel Rojo Posted August 31, 2020 7:16 pm

      Don’t all yorkie ears eventually perk up, yes some more than others, but a true yorkie shouldn’t have floppy ears after six months, am I right?

      • Diana Kitch Posted September 13, 2020 8:10 pm

        Some Yorkies ears do not stand up. I have AKC Yorkies and I breed Yorkies.I have to tape them to go up sometimes and they are AKC very good looking Yorkies. They might have stood up on their own, but I always tape them up and they will stay up after you take the tape off in around two weeks.

  • Annie Posted July 15, 2018 2:33 pm

    I am struggling to find information on coat development that does not include colour. Some dogs seem to have long coats from a young age and others seem to have a thinner coat. Do you have some websites with pictures you can recommend, please?

  • Yazmin Posted July 20, 2018 5:21 am

    Somebody knows how’s the character on 8 months puppy’s ? Because mine is acting little be queer with me.

    • Kat Posted December 30, 2018 4:28 pm

      Please describe exactly what you mean. If you are saying your puppy acts wide and crazy at times…that is normal. He is probably overwhelmed or tired. If you take note the times he behaves this way, I bet you discover it happens around the same time every day or during the same activities. Give him a break at these times. Lovingly put him in his crate/bed and let him settle down on his own. He will grow out of this.

    • Sandy Posted January 14, 2019 8:43 pm

      At 8 months they become more independent. If your dog was mostly walking next to you on walks, it might now want to walk in front of you. Exploring the area more, meaning it might try to go through the fence and walk around the neighborhood, even if it never did,that before. Acting up, not listening when you call it to come. Might start barking more. It’s important to still maintain rules and not giving in because your dog is so cute. It’s also important to still socialize your dog, let it meet other dogs of it’s own size and let it meet lots of humans and children, to prevent it to become skittish or have anxieties. Talk to your dog too. They learn language just like we do. It’s the puberty face. Lots of love, patience and rules.

  • Bubba Posted August 24, 2018 4:18 am

    My little Bubba will be 3 mos Sept 1, and he’s got a very active personality, he plays and chases big brother Charlie, a terrier 3 yrs old, He’s very alert and loved to play with any and all toys, he’s a delight, last weight check was 1.7 and has a beautiful teddy bear face

  • Brigitte Posted December 17, 2018 9:26 am

    I have 2 yorkie puppies of exactly the same age (10 weeks) but not related. Both lots of parents are same size- and all are registered… One pup is 640g and one is 930g. Do puppies grow at different speeds or does this simply mean the one will always be bigger than the other? Not much possibility of them being the same size?

    Many thanks and kind regards

    • YorkieLife Posted December 17, 2018 1:15 pm

      Hi Brigitte,

      Yes, it’s normal for puppies to grow at different speeds even if they are from the same litter. Your puppies most probably won’t be the same size even though it is too early to tell yet. After the sixth-seventh month more or less you will be able to see their difference more accurately.

  • Nicola Posted March 2, 2019 9:19 pm

    Hi our Yorkieis a big boy. He weighs 8.8 kg. Why does everything I read seem to relate to teacup Yorkies? I’d like to feel he’s ‘normal’ !!! He is in proportion with his height and length.

    • Nancy Posted September 26, 2019 1:25 pm

      Kg or lbs, your says he’s 30+ pounds

      • Nancy Posted September 26, 2019 1:30 pm

        I mean 21+ lbs

  • Martha Estrada-Manzano Posted April 6, 2019 10:02 pm

    Our is 3 months old and his hair has not grown much any suggestions?
