Mini Bernedoodles are a delightful crossbreed known for their adorable appearance and friendly disposition. These pint-sized pups are a mix between the Bernese Mountain Dog and the Poodle, making them a popular choice among dog enthusiasts. One common question that potential Mini Bernedoodle Full Grown owners have is, “How long does it take for a Mini Bernedoodle to reach full growth?” In this article, we will explore the various stages of a Mini Bernedoodle’s growth, shedding light on when they reach their full size and maturity.

Prenatal Development

Before diving into the stages of postnatal growth, it’s essential to understand a bit about prenatal development. Mini Bernedoodles, like all dogs, undergo significant growth and development before they are born. The mother dog, or dam, plays a crucial role in ensuring the health and well-being of her puppies during this period, which typically lasts around 63 days.

During this time, the puppies’ organs and body systems develop rapidly. While it might not directly impact their eventual size, prenatal care and a healthy diet for the mother dog can contribute to the puppies’ overall health. However, the prenatal phase primarily sets the stage for their postnatal growth and development.

Birth to Six Weeks – The Early Stages

Once Mini Bernedoodle puppies are born, they are incredibly tiny, blind, and completely dependent on their mother for nourishment and care. During the first six weeks of their lives, their growth is exponential. They double, or even triple, their birth weight within this period. This phase is crucial for building their initial strength and immunity.

It’s essential for Mini Bernedoodle owners and breeders to provide a nurturing environment during this phase, including a clean and warm whelping area and appropriate nutrition for the mother to ensure the puppies get a good start in life.

Six Weeks to Six Months – Rapid Growth

The next phase of a Mini Bernedoodle’s growth takes place from around six weeks to six months of age. During this period, they experience rapid growth in both size and development. Mini Bernedoodles are known for their smaller size compared to their standard counterparts, and by the time they reach six months, they have typically reached a significant portion of their adult size.

The rate of growth can vary from one Mini Bernedoodle to another, but on average, they will reach approximately 50% of their adult weight during this time. It’s essential to provide them with a balanced diet and regular exercise to support their growth while keeping an eye on their overall health.

Six Months to One Year – Adolescence and Refinement

Between six months and one year of age, Mini Bernedoodles enter their adolescent stage. This phase is characterized by continued growth, though at a slower rate compared to the previous six months. Most Mini Bernedoodles will reach their full height by around nine months to a year, although they may continue to fill out in terms of muscle and body mass.

During this time, it’s crucial to ensure they maintain a healthy weight, as rapid weight gain can put unnecessary stress on their joints and lead to health issues later in life. Regular veterinary check-ups and proper nutrition are essential to monitor their overall health and development.

One Year and Beyond – Full Adulthood

By the time a Mini Bernedoodle reaches one year of age, they are considered fully grown in terms of height. However, they may continue to fill out and develop muscle tone for another year or so. It’s essential to provide them with a balanced diet and regular exercise to maintain their health and prevent obesity.

As Mini Bernedoodles reach full adulthood, their behavior may also stabilize, and they might become calmer and more predictable in their actions. It’s a great time to focus on obedience training and socialization to ensure they are well-adjusted and well-behaved companions.


In conclusion, the journey of a Mini Bernedoodle from birth to full growth is a remarkable one filled with rapid changes and development. Understanding the various stages of growth and providing appropriate care and attention during each phase is essential for ensuring your Mini Bernedoodle reaches its full potential.

While the exact timing of reaching full growth may vary from one Mini Bernedoodle to another, it typically occurs within the first year of life. Patience, proper nutrition, regular veterinary care, and plenty of love and attention will help ensure that your Mini Bernedoodle grows up to be a healthy and happy companion, bringing joy to your life for years to come.
