How Big Does a Mini Bernedoodle Get? Average Growth & Weight Chart

The Mini Bernedoodle is a hybrid breed that combines the best features of Miniature Poodles and Bernese Mountain Dogs. One common question that potential Mini Bernedoodle owners often ask is how big these dogs will get.

Knowing their growth pattern can help in planning for their housing needs, exercise requirements, and veterinary care. In this article, we’ll discuss the size and growth pattern of Mini Bernedoodles.


Mini Bernedoodle Breed Overview

Mini Bernedoodles are a relatively new breed bred for their intelligence, companionship, and hypoallergenic qualities. A Miniature Poodle’s cleverness and a Bernese Mountain Dog’s loyalty and affability make the Mini Bernedoodle a charming and bright breed that fits well into many households. They are also known for their playful energy, making them a great choice for active families.

The size of a Mini Bernedoodle can vary, largely depending on the parents’ size. Generally, they grow 18 to 22 inches tall and weigh 25 to 50 pounds when fully grown. Due to their manageable size, they are suitable for apartment living and larger homes.

When Does a Mini Bernedoodle Stop Growing?

Mini Bernedoodles usually stop growing in height around 11 to 12 months of age. After reaching their maximum height, they will continue to fill out, gaining muscle mass and a bit more weight until they’re about 14 to 16 months old.

However, it’s important to note that these timelines aren’t set in stone and can vary with each dog. Genetics, diet, and overall health will significantly affect a Mini Bernedoodle’s growth and development.

Factors Affecting the Size of Mini Bernedoodles

Several factors determine the size of a Mini Bernedoodle:


Genetics plays a significant role in determining a Mini Bernedoodle’s size. The puppies are likely to follow suit if the parents are larger or smaller for their breed. Breeders try to pair dogs that will produce puppies of the desired size, but genetics can be unpredictable, and variations occur.


Proper nutrition is a linchpin for healthy growth. Feeding your Mini Bernedoodle a balanced diet from puppyhood is essential to ensure they reach their full potential. Overfeeding, on the other hand, can lead to obesity, which can stunt growth and lead to other health issues.

It is crucial to follow feeding guidelines and adapt them to your pet’s specific needs, depending on their activity level and age.


Regular exercise is essential for a Mini Bernedoodle’s healthy development. Not only does physical activity promote cardiovascular health and muscle development, but it also plays a significant role in maintaining an ideal weight. A sedentary lifestyle can lead to obesity, adversely affecting the dog’s size and overall health.

It’s important to remember that while exercise is crucial, puppies should not be over-exercised, as their bones and joints are still developing.

Ideal Diet for Maintaining a Healthy Weight

Providing your Mini Bernedoodle with a balanced diet is crucial for maintaining a healthy weight and promoting optimal growth. Here’s what an ideal diet should include:


As the building block of cells, protein is vital for developing, maintaining, and repairing body tissues. High-quality, easily digestible animal proteins such as chicken, beef, fish, and lamb should form the bulk of your Mini Bernedoodle’s diet.


Carbohydrates provide your dog with energy and should be included in moderation. Complex carbs, like sweet potatoes, brown rice, and oats, are preferred due to their nutritional value and slow-release energy.


Fats are a concentrated source of energy, vital for brain development, and for maintaining a healthy coat and skin. Look for brands rich in beneficial fats, such as omega-3 and omega-6 fatty acids.

Fiber, Vitamins, and Minerals

These are essential for maintaining digestive health, promoting a robust immune system, and supporting overall well-being. They can be found in fruits, vegetables, grains, and dog-friendly superfoods.

High-quality commercial dog foods, particularly those designed for small to medium-breed puppies and adults, can meet the nutritional needs of Mini Bernedoodles. Remember to adjust the portions according to your pet’s size, age, and activity level to prevent overfeeding and obesity. Regular consultations with your vet can help you maintain an appropriate diet plan for your pet.

How to Measure Your Mini Bernedoodle

Keeping track of your Mini Bernedoodle’s size involves regularly monitoring their height and weight. If you’re uncomfortable measuring your dog or have difficulty doing it, your vet can always do it for you. If you’re ready to give it a try, here’s what you need to know:


To measure your dog’s height, make sure they’re standing on a flat surface. Measure from the ground to the top of their shoulders (the highest point of the withers), not the top of their head.


A pet or veterinary scale is the most accurate tool for weighing your Mini Bernedoodle. Ensure your pet is calm and still for an accurate reading. Regular measurements can help you track your Bernedoodle’s growth and ensure they are maintaining a healthy weight. Any sudden changes in weight or growth should be discussed with a veterinarian to rule out potential health issues.



Knowing how big your Mini Bernedoodle might get can be helpful for prospective and new owners. Understanding your pet’s growth chart aids in anticipating their future needs, from diet adjustments to exercise routines. With proper care, balanced nutrition, and a loving environment, your Mini Bernedoodle will grow into a healthy and loyal companion.
