How Big Do Mini Bernedoodles Get?

Meet the Mini Bernedoodle: Small in Size, Big in Personality

If you’ve found yourself asking, “How big do Mini Bernedoodles get?”, you’re in good company. At Fox Creek Farm Goldendoodles and Bernedoodles, this is one of the most common questions we hear from families getting ready to welcome a new pup. The answer is important—not just for curiosity’s sake, but because knowing what to expect in terms of size helps you prepare your home, lifestyle, and heart for the perfect fit.

Mini Bernedoodles may be “mini,” but there’s nothing small about their charm, intelligence, and loyalty. These dogs have taken the doodle-loving world by storm, combining the lovable traits of the Bernese Mountain Dog and the Miniature Poodle into a compact, hypoallergenic companion that suits a wide range of homes and lifestyles.

Before diving into measurements, let’s look at what exactly makes a Mini Bernedoodle… well, mini.

What is a Mini Bernedoodle, Really?

A Mini Bernedoodle is a designer hybrid breed—a mix between a Bernese Mountain Dog and a Miniature Poodle. The result is a pup that brings the best of both worlds: the warm, affectionate nature of the Bernese and the intelligence and low-shedding coat of the Miniature Poodle.

There’s also a variety of generations within this breed, which slightly affects their adult size. These include:

• F1 (first generation): 50% Bernese, 50% Mini Poodle 
• F1b: 75% Mini Poodle, 25% Bernese 
• Multigen: A mix of generations, bred for consistent size and temperament 

At Fox Creek Farm Goldendoodles and Bernedoodles, we focus on responsible, ethical breeding practices to help ensure that each Mini Bernedoodle grows into a well-balanced, healthy adult with a predictable size and temperament. All of our dogs—no matter the generation—are hypoallergenic, making them ideal companions for allergy-sensitive households.

How Big Do Mini Bernedoodles Get on Average?

Now, let’s get to the big question: How big do Mini Bernedoodles get? While exact size can vary slightly, most Mini Bernedoodles fall within a fairly predictable range once fully grown:

• Height: 14 to 17 inches at the shoulder 
• Weight: 26 to 35 pounds 

There are a few factors that can cause slight variation—such as gender, diet, and parental genetics—but this size range is typical for healthy, ethically bred Mini Bernedoodles. At Fox Creek Farm Goldendoodles and Bernedoodles, we carefully pair parent dogs to maintain this compact, family-friendly size.

Mini Bernedoodles tend to reach their full adult size between 12 and 16 months of age. Some hit their growth spurt early, while others grow gradually over time. It’s helpful to monitor weight and height during the first year so you can ensure your pup is developing at a healthy pace.

Factors That Affect How Big Mini Bernedoodles Get

Although most Mini Bernedoodles stay within the 26-35 pound range, several key factors can influence their final size. It’s not always an exact science, but understanding these variables can help you set realistic expectations.

1. Genetics and Generation

The biggest influence on size comes from the puppy’s parents. A Mini Bernedoodle with a smaller Miniature Poodle parent and a smaller than average Bernese Mountain Dog parent will likely mature on the smaller end of the scale. Conversely, if the Bernese parent was larger or if the breeding involves a Standard Poodle at some point, you may see a slightly bigger pup.

The generation also plays a role:

• F1 (first-gen) dogs tend to be a bit larger and have more variation in size. 
• F1b and Multigen Mini Bernedoodles are more predictable in size and often lean toward the smaller side due to their higher percentage of Mini Poodle DNA. 

At Fox Creek Farm Goldendoodles and Bernedoodles, we are intentional about selecting breeding pairs with optimal size compatibility to maintain our Mini Bernedoodles’ compact, manageable stature.

2. Nutrition and Diet

Just like people, dogs grow best when they’re properly nourished. A Mini Bernedoodle that receives a balanced, high-quality diet will grow at a healthy pace and achieve their ideal adult weight. Overfeeding, however, can lead to excess weight gain, making your Mini Bernedoodle seem larger than expected—though not due to genetics.

3. Exercise and Lifestyle

Mini Bernedoodles are playful and moderately active. A puppy with consistent physical activity will develop strong, lean muscles and maintain an appropriate weight. While exercise doesn’t necessarily make them “bigger,” it helps shape their body in a healthy way. A sedentary lifestyle, on the other hand, can lead to unwanted weight gain that impacts their overall frame.

4. Health and Hormones

Spaying or neutering a Mini Bernedoodle at a very young age may have a small influence on how tall or broad they become. It’s not drastic, but hormone levels can affect bone development. This is why it’s important to follow your vet’s guidance when planning for those milestones.

Growth Timeline: What to Expect as Your Mini Bernedoodle Matures

Understanding how Mini Bernedoodles grow helps you better answer the question: How big do Mini Bernedoodles get over time? Their growth happens in distinct phases.

Here’s a general overview of what you can expect:

• Newborn to 8 weeks: Tiny, fluffy, and growing fast. Puppies will typically triple or quadruple in weight. 
• 8 to 16 weeks: Major growth spurt. You’ll notice long legs and rapid weight gain. 
• 4 to 6 months: Puppy energy is in full force. This is where you may start to guess their adult size based on growth trends. 
• 6 to 12 months: Slower, steadier growth. Most Mini Bernedoodles reach about 75% of their full size by 9 months. 
• 12 to 16 months: Final touches—filling out their frame, developing muscle tone, and growing into their adult proportions. 

Quick Tip: Keep track of your puppy’s weight every two weeks during the first six months. It’s a helpful way to spot growth patterns and check in on their development.

Mini Bernedoodle vs. Standard Bernedoodle: How Size Compares

If you’re still wondering, “How big do Mini Bernedoodles get compared to the standard ones?”—you’re not alone. Many families explore both sizes before making a decision. While both share the same sweet personality, trainability, and hypoallergenic qualities (especially when ethically bred like those at Fox Creek Farm Goldendoodles and Bernedoodles), their size differences can influence your choice depending on your home and lifestyle.

Here’s a quick comparison:

Why Size May Matter for You

• Living space: Mini Bernedoodles are well-suited for apartments or smaller homes. 
• Ease of travel: Their smaller frame makes car rides and vacations much simpler. 
• Handling & grooming: Grooming a Mini Bernedoodle is less time-consuming due to their compact size. 
• Family fit: They’re great with children, but their manageable size makes them less likely to knock over small kids by accident. 

So while the Standard Bernedoodle is a lovable, gentle giant, the Mini Bernedoodle is a pint-sized package of intelligence and affection—making them an ideal choice for families or individuals who want a medium-sized dog with a big heart.
