Bernese Mountain Dog Growth ChartDespite looking like a teddy bear that would fit right in your arms as a puppy, once this gentle giant grows to its adult size, you’ll see just how large these dogs can be. As such, it’s important that you keep track of their growth rate — this Bernese Mountain Dog growth chart can provide the best way for you to do this. So before you purchase or adopt one of these big dogs, consider if you have enough space for them to move around comfortably in your home. 

What is the Bernese Mountain Dog? 

With its large size, sturdy body, and beautiful coat, the Bernese Mountain Dog was built for hard work and served as an intimidating watchdog and a companion for watching cattle. They come with an affectionate and sweet nature; they’re always up for playtime and are eager to please their owners. Like many larger breeds, this dog will stand at over 27 inches at its shoulders and will come with a silky, long, and thick coat that comes in three colors which are black, rust, and white. 

The breed is also known for the distinctive markings on its face and coat, which are combined with its dark eyes, giving it an aura of nobility and majesty. This hardy dog flourished in cold weather and has been built to multitask around the pastures and farms of Switzerland. Your Berner puppy will get along with everyone, and will also be gentle with little kids but will likely become more attached to their chosen human. 

While these dogs may look imposing, they’re not threatening in any way and will maintain an aloof personality with strangers. However, these dogs are known for their good nature and temperament, making them a wonderful family companion.  

When Do Bernese Mountain Dogs Reach Full Size?

Larger dogs will take a longer time to reach their adult size compared to smaller dogs because of their size. Small breeds will usually take a year to finish growing but large breeds like the Bernese Mountain Dog will need 2 to 3 years to reach adulthood. However, even after their 3rd year, some Berners will continue growing and may get bulker as time goes by. 

At 18 months of age, most dogs will reach adulthood but the Bernese Mountain Dog will still be awkward on its feet and will still look like a puppy. Both their emotional and mental maturity will come after their physical maturity, so they will retain puppy-like behavior. However, your puppy’s weight will be affected by various factors such as exercise, nutrition, health conditions, and genetics. 

To help your puppy grow at the right rate, be sure to give it a balanced diet, and enough exercise while taking it on regular visits to your vet. By the time it reaches 3 months, you should see around 20 to 35 pounds of puppy growth. At 6 months of age, your pooch should weigh between 45 to 70 pounds.   

By its first year, your puppy should have a weight between 65 to 105 pounds. Once it reaches adult weight at 2 years of age, it should weigh between 80-115 pounds. Below is a Bernese Mountain Dog weight chart to help you calculate if your puppy is reaching the right weight at the right time.

Bernese Mountain Dog Puppy Stages

Below are the most important developmental stages that your Bernese Mountain Dog puppy will undergo before it finally reaches adulthood that you will need to observe to ensure proper growth. 

Birth to 2 Weeks

Just like any puppy, your Bernese Mountain Dog will be born deaf and blind, which means it won’t be able to hear or see anything so it will spend most of the time feeding, sleeping, and growing. They will also be too weak to move around as their leg muscles haven’t fully developed yet. Your puppy will try to stand or sit up and stay with their mom inside their sleeping area as much as possible. 

All puppies will get the nutrition they need from their mother’s milk at this stage since it will contain everything needed to support their growth. If the mother isn’t producing enough milk, you can give your puppy some formula instead. 

3 Weeks to 12 Weeks

By the time they reach 3 weeks old, your puppy’s ears and eyes will be fully developed and its leg muscles will start getting stronger. They will also begin exploring around the house and will interact with others in their litter — this is the best time to start socializing your pooch. When they turn 4 weeks old, you can start weaning them off from their mom’s milk and introduce them to puppy food but don’t force them to switch over if they’re uncomfortable with it. 

At 8 weeks old, your puppy will be ready to move to a new home which means that they should be weaned completely. They should be fed at least 4 times a day and should be dewormed and vaccinated. 

4 Months to 9 Months

At the ages of 4 to 5 months, your Bernese Mountain Dog pooch will lose its puppy teeth and start to get its adult teeth. This can be an uncomfortable and painful experience for your puppy as its gums get more tender — at the same time, they will also shed their puppy coat, so be sure to brush them to remove the fluff to make room for their new coat. Continuous socialization and training are important during this time to make sure your pooch develops good habits into adulthood.    

10 Months to 18 Months

By now, these large-breed dogs will grow into young adults and will start going through sexual maturity, and will be a good time to consider neutering or spaying them if needed. Due to the creation of reproduction hormones, they may begin behaving differently, forget everything they learned during training, and may become restless. As such, more training will be needed to control their dominance and let them know that you’re the pack leader and not your puppy.  


As mentioned, your Bernese Mountain Dog will take around 2 to 3 years to reach its adult height and weight because they grow slower compared to other breeds. Their body will continue to grow until they turn 3 years old, so it’s best to wait until they reach 2 years old before transitioning them from puppy to adult food. Bernese Mountain Dog puppies can be high-maintenance and when they grow into adults, they can become heavy droolers. 

When this happens, you’ll need to wipe away the slobber if you don’t want it getting on everything inside the house. Even so, these fantastic farm dogs come with a good-natured and calm personality that allows them to get along well with children and other pets.    

How Big Does a Bernese Mountain Dog Get?

As you already know, these dogs can grow to huge sizes but it could be difficult to imagine just how big they can get once they become full grown. Luckily, there are a few ways for you to predict how big your puppy will get. The first way to do this is to look at your puppy’s parents to get a clear idea of what your adult puppy might look like. 

If you know how big your puppy’s parents are, calculate the average of their combined weight to find out your puppy’s estimated adult weight. You may be able to get this information from your breeder but if your dog is adopted and you’re not sure what breed it is, then consider doing a DNA test to find out its genetic makeup. Finally, you can check your dog’s paws to see if it’s reached its final size.

If the paws look bigger than its body, then your pup is still growing and will look more proportional once it reaches adulthood. 

Male vs. Female Bernese Mountain Dogs 

Most of the time, female dogs will be slightly smaller and lighter compared to their male counterparts. The same case applies to the female Bernese Mountain Dog, which will only grow up to 23 to 26 inches and weigh between 70 to 95 pounds, while the males can grow as tall as 25 to 27.5 inches, weighing as much as 80 and 120 pounds. If you want to find out how tall your dog is, it’s easy to do it from the comfort of your home. 

All you need is a measuring tape and take a measure starting from the ground to your pup’s withers. To get a more accurate estimate, make sure that your pooch is standing up straight. 

Will Spaying or Neutering Stunt its Growth?

Spaying and neutering are processes that remove the uterus of a female dog while neutering removes the testes of a male dog. Removing the reproductive organs of your puppy before it reaches their maximum height may affect their growth. The reason for this is that reproductive hormones are needed to close the growth plates, and without them, dogs may develop joint issues as a result of growing taller.   

However, spaying at the right time can help to prevent unwanted pregnancies, while minimizing the risk of cancers such as cervical and mammary cancer. For male dogs, neutering can minimize aggressive behavior, reduce the chances of testicular cancer, and stop them from impregnating females that are intact.

Factors Affecting Bernese Mountain Dog Growth

Below are just a few things to consider when it comes to the growth of your Bernese Mountain Dog.

Genetics and Gender

As mentioned above, looking at your puppy’s parents can help you determine how big your dog can get once it grows. Checking on the parents of your puppy can give you a good indication of how big it can get in the future based on their breed, size, and weight. Small dogs will typically produce small offspring while large dogs will have big babies, so the parent’s size will have a significant impact on how the puppy will look as a newborn. 


A balanced and healthy diet can ensure that your dog grows to full height while staying healthy, so be sure to give your dog high-quality dog food. To get an idea of the best brands to choose from, you can read up on our list of best dog foods or you may speak to your veterinarian for guidance. You may also give your pooch a raw diet that includes raw meat and veggies, but may not be the best option for people with a busy schedule. 

Your Bernese Mountain Dog should be fed meals twice a day. Giving them too many snacks is discouraged, but if you do give them something to snack on, be sure to reduce the amount on their next meal. 

Physical Activity and Health

Bernese Mountain Dogs will naturally come with high energy levels because of their background as working dogs, so they will need plenty of mental and physical stimulation. Be sure to give them a minimum of 1 hour of exercise every day which can be divided into two or more sessions. One way to keep your dog active is to take it on a 30-minute walk and out in the yard for an hour of play and games.  

Bernese Mountain Dog Health Problems

If you do plan to care for one of these dogs, there are a few health issues with your Bernese Mountain dog that you need to be aware of, including the following. 

  • Progressive Retinal Atrophy (PRA): This eye disease is inherited from parents and causes the dog’s retina to degenerate, leading to partial or complete blindness. Unfortunately, there is no cure for this disease, so be sure to check the puppy’s parents before purchasing or adopting.
  • Hip Dysplasia: Known as a common condition in larger dogs, hip dysplasia is usually present in Bernese Mountain dogs because it’s also hereditary. It refers to the incorrect formation of the hip socket and the femur bone, resulting in pain within the affected joints. 
  • Elbow Dysplasia: Just like the condition above, this refers to a deformity of the elbow joint and can be seen as early as the puppy’s 4th month. Symptoms of this health issue include the inability to properly use their forelimbs and a build-up of fluids in their joints.
  • Von Willebrand Disease: This common condition causes genetic blood clotting in dogs, causing severe bleeding from even the smallest injuries. 
  • Histiocytosis: This is another genetic condition that’s common in Berners — this type of cancer may lead to death if left untreated.     

Bernese Mountain Dog Growth FAQs

If you plan on raising these dogs, you may have a few questions that need to be answered. Fortunately, we have all the information you need below. 

How Much Do I Need to Feed My Growing Puppy? 

How much your puppy eats will steadily increase as it grows; a healthy puppy between 8 to 10 weeks old should get around ¾ to ½ cups of food for every meal. Once they turn 2 to 6 months old, they should be switched over to 2 meals per day. However, keep in mind that every puppy will be different and will have different needs depending on their activity level, diet, and genetics. 

A puppy that’s 4 months old will need more food compared to an 8-week-old puppy. Once a dog reaches 6 to 8 months old, it can start taking adult food portions or more depending on their routine and environment. In general, a healthy adult Bernese should be given around 3 to 6 cups of high-quality adult dog food each day. 

How Do I Tell if My Dog is Underweight Or Overweight?

Your dog’s weight will fluctuate many times throughout their lifetime, but if you see a noticeable change in their weight and your formerly skinny dog is accumulating fat, then there could be a problem. Your dog gaining or losing weight may indicate a problem with your dog’s health. If your pooch isn’t brought back to a healthy weight, there may be a risk for it to develop serious problems that will affect their quality of life. 

However, there are times when their weight gain can be gradual and the changes may not always be noticeable. Below are a few ways for you to tell if a dog is underweight or overweight. The first way to do this is to run your hands over your dog’s sides; if you can’t feel your pup’s ribs then it may have too much fat which means it’s overweight. 

Your dog will be classified as underweight if you feel too many ribs between the skin and you can’t feel much between them. Another way to tell is to gently run your hands down your pup’s spine — you should be able to feel its bones, but they shouldn’t be protruding. If their bones seem to be buried under fat and you can’t feel them, then your pup is overweight but if you feel your pooch has little to no flesh with a well-pronounced spine, then it’s underweight.

How Do I Properly Weigh My Bernese Mountain Dog?

If you’re looking to weigh your pup, there are a few ways to do so but it can get harder to do as your pooch gets bigger. Be sure to weigh your dog once a month to keep track of its progress — make sure you use the Bernese Mountain Dog size chart above to get an idea of where your dog is in terms of weight gain. While you still have a small puppy, you can use a bathroom scale while holding the puppy and weighing it yourself. 

You should be able to feel the difference each month when you weigh your canine companion — it can become a challenge to lift them when they grow too big. If you’re unable to weigh it by yourself, you can visit your vet where there might be a large scale for bigger dogs. 


While they originally came from the Swiss Alps, the Bernese Mountain Dog’s immense size can find its way over to the homes of many pet parents who will find their good behavior to be a delight. However, they won’t all grow at the same pace, and dog owners will need to keep a close eye on the progress of their individual dogs. The amount of food you feed your pup will affect their final weight, and using a puppy weight chart will be a great way to keep them happy and healthy starting at a young age.
