When Do Bernedoodles Stop Growing?

Bernedoodles are remarkable dogs. They are the perfect mix between a Bernese Mountain Dog and Poodle. These designer doodles are well-loved and praised by many. But there is one question that seems to be on the back of every owner’s mind; when will my Bernedoodle stop growing?

The simple answer to the question relies on identifying the dog’s parentage. Bernedoodles will reach their full size and weight when they reach the age of 2. So, depending on the type of Bernedoodle you have, you’d be able to determine their estimated size.

Let’s Talk About the Breed

Bernedoodles make great house pets. They get along with kids and other animals as well. They quickly adapt to their space, and as long as you give them the right amount of love and attention, you’re looking at one of the best breeds to have at home. 

This breed is relatively new. They have only been around since 2003. This means we’re still learning about them too. As time goes by, we know more about the breed, giving us a better understanding of their characteristics and traits.

Bernedoodles are ideal for people who have sensitivity to dog dander. While there is no such thing as a completely hypoallergenic dog, the Bernedoodle sheds minimally, thus making them suitable for people with allergies. 

Their coats vary in color and texture. Choosing the perfect one may be a challenge since they are all quite adorable. They also come in different sizes; tiny, miniature, and standard. Their Poodle lineage often determines their sizes since they come in toy, miniature, and standard sizes. 

When Will My Bernedoodle Stop Growing?

As mentioned, your Bernedoodle’s size is predetermined by their Poodle influence. You will also need to take into consideration their Bernese Mountain Dog genes. With larger breeds, they take longer to reach the peak of their maturity – this simply means that it will take time for them to get their adult size. Therefore, Standard Bernedoodles will continue to grow longer than a Tiny or Micro Bernedoodle would. 

Ideally, they reach their full size at the age of 2, but that is just an estimation. There is still a lot that we need to learn about the breed to be certain, but we learned that they do indeed reach adulthood by that time in the past decade.

Other factors influence their size aside from genetics. Proper nutrition, disease, and environment may also play a role in determining the maximum size your Bernedoodle would reach.

What Are the Different Sizes of Bernedoodles?

As breeders ourselves, we responsibly choose the best breeding pair. We make sure that the parents are of good genetics and character that would give you the best pup. Let’s talk about the different kinds of Bernedoodle sizes:

Micro Bernedoodle

The smallest version of the Bernedoodle that we have is the Micro. They are the result of a Bernese Mountain Dog and Toy Poodle pair. They are the smallest of the Bernedoodle breed. This type usually stops growing at 12 to 18 months and grows as tall as 17 inches in height. They are expected to be 10 to 24 pounds.

The Micro Bernedoodles reached their final weight and size by the time they are a year old. After that, however, they seem to grow at a faster rate. As soon as they hit the one-year mark, their growth slows down.

Miniature Bernedoodle

Miniature Bernedoodles are a bit bigger than the Micro Bernedoodles. This is because they come from a Bernese Mountain Dog and a Miniature Poodle. This type of Bernedoodle takes less time to grow compared to that of a Micro, and you can expect your Miniature Bernedoodle to be fully developed by their 11th or 13th month. 

By their first birthday, you can expect them to reach their full height and weight. They would be as tall as 22 inches and weigh anywhere between 25 to 50 pounds. They seem to gain weight reasonably quickly as pups. Ideally, they should be 25 to 28 pounds by their 6th month. The weight then eases in as they continue to grow.

On the other hand, their height is more noticeable during the first six months of their lives. After that, it becomes more gradual.

Standard Bernedoodle

The largest Bernedoodle type is the standard. The standard Bernedoodles are a result between a Bernese Mountain Dog and a Standard Poodle. Being the largest of the three types, they take the longest to reach their full size. 

You can expect them to reach their full size by the age of 18 to 24 months. After that, it may take them longer to grow, but they will get as big as 29 inches tall and weigh as much as 90 pounds. By the 6th month mark, they should weigh as much as 45 pounds. After this point, their growth will be slower than usual, but you will notice an evident increase in their weight and height.

What Are The Factors That Can Affect Their Growth?

Since Bernedoodles are mixed breeds, we can only provide you with estimates on their sizes. These figures are not entirely set in stone, and different factors may affect their growth.


A Bernedoodle’s size and weight are primarily dependent on their parents. The type of Poodle used often determines the type of Bernedoodle you get. If a Toy Poodle is used, you’re most likely to get a Micro Bernedoodle. But, if you decide to buy from a different breeder who uses a Poodle that is not purebred, you might have a discrepancy in sizes. Here in Arrow T Pets, we make sure to use only the best breeding pair for our litters – this ensures a good and healthy litter of pups.

Food & Nutrition

When we estimate how heavy your Bernedoodle would get, this is based on proper health and nutrition. It is improbable that Bernedoodles would grow taller when they are already fully grown, but weight can vary and still increase after the fact. 

If your Bernedoodle is within the weight range of their type, you should not be worried. However, whenever you visit your vet, be sure to have their weight checked and keep track of it to know if they are under or overweight.

With healthy Bernedoodles, you should be able to touch their ribs slightly, but they shouldn’t show through their fur. Vets are great at providing tailored advice on how to keep your Bernedoodle in the best shape.

One thing that genuinely affects weight is food and nutrition. Bernedoodles that are not appropriately fed tend to be underweight. While Bernedoodles that are given table scraps and constantly snack would have problems with weight gain.

Physical Activity

Since weight depends on nutrition, the amount of physical activity your Bernedoodle gets plays a factor in their weight. When they get enough exercise in a day, they consume the excessive calories they might be consuming.

Bernedoodle Growth Chart

As we have said, the growth of a Bernedoodle depends on which type you get. But here is a quick run-down of what you should expect when you have bought your first pup.

Day 0 to 2 Weeks

A newborn Bernedoodle weighs at least a pound at birth, and their weight doubles up in the first few weeks. During this time, they are utterly dependent on their mamas. This is why it is also essential that the moms are in the best health. This is something we can assure you at Arrow T Pets. Healthy parents and healthy pups. 

3 Weeks to 12 Weeks

Standard Bernedoodle puppies grow pretty quickly. By week 12, they would weigh as much as 35 pounds. At this point, they can be safely weaned from their mamas. But, be careful; this is also when they get themselves into a lot of mischiefs. 

4 Months to 6 Months

By the time a Standard Bernedoodle reaches this age, they can weigh anything between 45 to 55 pounds. Their growth will slow down at this point, but their appetites will increase. They would need to be fed 2 to 3 meals a day to get the right amount of calories. But, again, their growth slows down by this age. 

7 Months to 9 Months

During this time, you will start seeing the final size of your Bernedoodle. A Standard Bernedoodle will weigh about 60 pounds by this age. But they are not entirely done growing.

10 Months to 12 Months

Even if growth has significantly slowed down by the 6th-month mark, there is still growth evident during this age. Just before their birthdays, a Standard Bernedoodle will weigh about 65 to 70 pounds.


Bernedoodles reach adulthood by the age of 2. This is when they stop growing, but their weights may vary depending on their nutrition and exercise.


At this point, we can say that Bernedoodles stop growing between the ages of 11 to 24 months. This estimate is dependent on what Bernedoodle type you have and how they are taken care of. The first six months of their lives are crucial, and this is where you will notice rapid growth, any time beyond that would be considerably slower. 

By the end of the two-year mark, the Bernedoodle should stop growing in height as it is already considered an adult dog by then. But weight is something else that will be determined by the amount of exercise they get and the quality of food you provide.
