Mini Goldendoodles are a popular hybrid breed, known for their affectionate temperament, hypoallergenic coats, and manageable size. But how big does a Mini Goldendoodle get? If you’re considering adding one to your family, understanding their expected growth and size can help with planning their care, training, and space requirements.
In this guide, we’ll cover Mini Goldendoodle growth stages, a detailed size chart, factors affecting their size, and how they compare to other Goldendoodle varieties to help you make an informed decision.
Goldendoodle Growth Stages: Month-by-Month Breakdown
Just like any other breed, Mini Goldendoodles go through different growth phases from birth to adulthood. Understanding these stages can help pet owners track their puppy’s development and ensure they are growing at a healthy rate.
- Neonatal Stage (0-2 Weeks): Newborn puppies are tiny, typically weighing around 1 pound at birth. During this period, they are entirely dependent on their mother for nutrition and warmth. Their eyes and ears remain closed, and their primary activities are nursing and sleeping.
- Transitional Stage (2-4 Weeks): Between two to four weeks, puppies begin to open their eyes and ears, becoming more aware of their surroundings. They start to interact with their littermates, initiating early social behaviors.
- Socialization Stage (4-12 Weeks): This critical phase involves rapid growth and development. Puppies become more active, playful, and curious. By eight weeks, they may weigh between 4 to 9 pounds. It’s an ideal time for basic training and exposure to various environments to foster well-rounded adult dogs.
- Juvenile Stage (3-6 Months): Growth continues steadily. By four months, many Mini Goldendoodles reach approximately half of their adult weight, ranging from 10 to 18 pounds. They develop muscle tone and coordination during this period.
- Adolescent Stage (6-12 Months): Growth rates begin to slow. By nine months, they often stand between 15 to 20 inches tall and weigh between 18 to 30 pounds. Behavioral maturity may lag behind physical growth, so continued training and socialization are crucial.
- Maturity (12-24 Months): Most Mini Goldendoodles reach their full adult size by 12 months, though some may continue to fill out until 18 months. Adult weights typically range from 20 to 35 pounds, with heights between 14 to 18 inches at the shoulder.

When Will My Mini Goldendoodle Stop Growing?
Most Mini Goldendoodles stop growing in height by 12 months but may continue to fill out until 16-18 months.
Growth Plateaus:
- 7-10 months: Growth slows down

- 12-18 months: Muscle development and slight weight increase
Once they reach adulthood, proper diet and exercise are crucial to maintain a healthy weight and muscle tone.
Factors That Influence Mini Goldendoodle Size
Several factors determine how big a Mini Goldendoodle will be:
- Genetics – The size of the Miniature Poodle and Golden Retriever parents plays a major role in the puppy’s final size.

- Diet & Nutrition – Proper protein-rich diets ensure optimal growth, while poor diets may lead to stunted development.
