First Two Weeks

During the first days of their life, Biewer Terriers are completely dependent on their mother, as they’re the main source of food, security, and warmth.

Newborn puppies can’t hear, see, or move until they’re at least three weeks old, and they are not even aware of their siblings… only their mother.

Therefore, don’t be surprised if your Biewer Terrier puppy spends the majority of time laying around and sleeping. The only time it’ll be awake is when it is breastfeeding.

This is the period during which puppies are most vulnerable, which is why you should pay more attention to them, especially since Biewer Terriers are a toy canine breed.

At this point, they probably won’t weigh more than one or two pounds.

First Two Months

After the first two weeks, puppies will be able to open their eyes and finally become aware of their surroundings.

The process of weaning should begin around the third or fourth week of the pup’s life. The best way to do this is by moving the mother from the puppies a few times a day for at least an hour.

This is also the right time to introduce puppy food, which contains a high amount of calories needed for the proper development of these pups.

During the second month of their life, Biewer puppies become interested in everything around them, so you might find them snooping around the house most of the time.

You will notice that your pet is beginning to grow at a faster pace, which is completely normal for this stage of their life.

This is the right time to begin potty and socialization training. Keep in mind that Biewer Terriers can often display stubbornness, which is why it’s important to start training them from early puppyhood.

Two Months To Six Months

The phase of fast growth is still ongoing, and according to the Biewer Terrier growth chart, six-month-old puppies should weigh between two and six pounds.

The majority of physical changes happen during this period, but you also might notice certain changes in the canine’s behavior.

While they’re still young, Biewer puppies spend most of their time napping and cuddling in your lap. However, as they get closer to their “teenage” stage, they will become more curious, playful, and mischievous.

Don’t underestimate them because of their size, as these pups might make quite a mess around the house, especially if they’re not properly trained from the first weeks of their life.

Six To Ten Months

This is one of the most challenging periods for the majority of pet owners, as this dog breed goes through major changes both mentally and physically.

Although they won’t develop at the same pace as they did in their first few months, the changes they go through can greatly impact their personality and general well-being.

This has a lot to do with spaying/neutering. It is strongly recommended to sterilize tiny dogs like Biewer Terriers, Yorkshire Terriers, Pomeranians, Brussels Griffons, and others in the period from six to nine months.

The main reason for the “early” sterilization is the fact that small dog breeds develop faster than large breeds.

The puppy weight of Biewer Terriers at this point can go from three to six pounds, after which they enter the adult stage.

Ten Months To One Year

At this point, your pooch is turning into a puppy adult, or as Britney would say, “not a girl, not yet a woman”.

Essentially, this means that your canine has reached adult weight (which is usually the case), but it might not be mentally ready yet to be called an adult.

This is especially true for playful and stubborn breeds like Biewer Terriers, so don’t be surprised if they still act naughty from time to time.

One of the main tasks of the owner is to maintain dominance over the dog. I know this might sound funny since you’re not raising a Cane Corso, but with a tiny pup, however, as I stated above, you shouldn’t underestimate Biewers just because of their size.

Of course, you shouldn’t be too harsh on them either. Try to find balance during training by using different methods, including positive reinforcement, and a rewarding system.

Just like any other pup, Biewer Terriers love snacks, and a delicious treat after training and good behavior can go a long way.


The majority of Biewer Terriers reach their maturity around the first year of life, but this doesn’t mean that the development process is fully completed.

The height of the Biewer Terrier won’t change significantly, as a great number of these dogs grow up to 11 inches at most (the average height is usually around 9 inches).

However, even after the pups turn one, their teeth and bones will continue strengthening. Their coat might become thicker as well, but that won’t affect their shedding cycles.

These dogs are known as a hypoallergenic breed, meaning that they don’t shed often, so you don’t have to worry about lumps of hair around the house.

If you haven’t made the switch from puppy to adult dog food, now is the right time. Even though a puppy diet won’t harm an adult canine, it is still recommended to make the transition around the first year.

By feeding your pet adult dog food, you will enable it to receive nutrients that are essential for its health.

When Are Biewer Terriers Considered Fully Grown?

These lovely pups usually take nine months until they’re considered fully grown in terms of height and weight, although some doggies might take two to three months longer.

Biewer Terriers can grow between seven and eleven inches, depending on the height of their puppy parents, their health, and other factors.

These doggies are amazing for many reasons, including the fact that although they become mature earlier than big dogs, they live far longer than them.

The lifespan of these tiny pooches is 16 years, just like the lifespan of Yorkies, Poms, Chihuahuas, and other small pups.

Which Factors Can Affect The Growth Of Biewer Terriers?

Biewer Terrier growth charts and puppy weight charts represent the average growth pace of this breed from the first days of their life.

However, weight and height can’t be the same for all dogs. These parameters will depend on different factors, including genetic background, diet, and the amount of physical activity.


A balanced diet is key to the healthy development of any puppy, especially small doggies like Biewer Terriers.

You can feed your pet human foods such as meat, fruits, and veggies, which contain high amounts of proteins, vitamins, and minerals.

This topic is especially important for Biewer Terriers that are susceptible to hypoglycemia – a medical condition that can be caused by malnutrition and inadequate diet.

In order to prevent this type of health issue, you need to feed your pup food that is rich in proteins, which will give the canines enough energy.

If you decide to introduce human foods to Biewer Terrier puppies, you need to make sure that the ingredients are safe for them, and that they won’t have any negative impact on their growth and overall development.

Genetic Background

The genes of puppy parents play an important role in the puppy’s growth process.

That is why you can predict the size of your pup based on the size of its parents.

If you either bought your puppy or adopted it, you can contact the Biewer Terrier breeder and gather all information about the parents of the pup.

This is just one of the reasons why it’s important to do thorough research on breeders before you decide to get a puppy.

If you go for a puppy mill or a backyard breeder, there is a great risk of ending up with a dog that is not healthy, not purebred, and of unknown origin.

Physical Activity

The amount of exercise your pet receives is crucial for its development.

If dogs receive proper training and enough exercise throughout the day from early puppyhood, their puppy weight will stay within healthy parameters.

Biewer Terriers possess high energy levels, which means that they need to be active on a daily basis.

Physical activity not only has an impact on their physical health, but also on their mental development.

Pups that don’t get enough exercise throughout the day might start to show signs of destructive behavior, especially if they’re as strong-willed and playful as Biewer Terriers.

How To Measure A Biewer Terrier?

A Biewer Terrier growth chart can be a good general guideline for the size of this pup.

Another way to know the optimal size of your pup is to use the puppy weight calculator, although these numbers might vary, depending on the pace of the dog’s growth.

If you prefer to measure the dog by yourself, you can check its weight by using the bathroom scale.

There are two ways to weigh your pooch. One of them is to weigh yourself without the dog first, and then repeat the action with your pet. The difference in weight is the actual weight of your pup.

Since Biewer Terriers don’t grow large, you can also put them into a measured container and weigh them on the bathroom scale.

However, height measuring might be a bit challenging as these pups rarely stand still. Once you’re able to keep the pup calm next to a wall, find its withers and mark its height on the wall.

By measuring the space between the floor and the marked spot, you will get the height of your beloved pooch.

Are Biewer Terriers Bigger Than Yorkshire Terriers?

These two dog breeds are often compared to each other because of their size. Many people believe that Biewer Terriers and Yorkies are of the same size, which isn’t actually true.

Although they look almost the same in terms of weight and height, there are certain differences between them.

Firstly, Biewers are a bit bigger than Yorkies. While the first ones might grow up to 11 inches in height, Yorkshire Terriers usually don’t grow over 9 inches.

The same goes for their weight. Yorkshire puppies can weigh up to 7 lbs at most, which is one to two pounds less than the weight of Biewer doggies.

Keep in mind that both weight and height depend on the individual pup, so there’s still a possibility that some Biewer and Yorkshire Terriers will grow to be the same size.

Wrapping Up

The Biewer Terrier growth chart can be helpful for dog owners who’d like to track the growth process of their furry buddies.

Keep in mind that the numbers mentioned within the weight chart of these pooches are rather a prediction of the pup’s weight.

A pound more or less than what is stated in the chart won’t cause an issue, but if you notice a greater discrepancy, you should consult a vet and change the dog’s diet, if necessary.
