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.

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.

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.

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.

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.

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.

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?

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

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.

Yorkie growth chart in kg

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

Height

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.

Weight

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.
