F1B Goldendoodles are a popular hybrid breed, and one of the most common questions potential owners ask is how big they'll get. On average, F1B Goldendoodles typically weigh between 40-80 pounds.
Their adult height can vary, but generally ranges from 18-24 inches at the shoulder. This makes them a great fit for families with smaller living spaces or those who want a dog that can keep up with their active lifestyle.
Growth and Development
Goldendoodles are a hybrid breed, making it difficult to predict their adult size. However, by understanding their growth patterns, you can get a better idea of how big your F1b goldendoodle will get.
Most F1b goldendoodles will stop growing around 16-18 months old. However, their growth curve will slow down significantly by the time they are 10 months old, with the most growth happening between 2 and 8 months.
You can estimate your puppy's adult weight by multiplying their 8-week weight by 4.3 for mini goldendoodles. For standard goldendoodles, you can multiply their weight at 4 months by 2 and add 5-10 pounds.
Will My Puppy Grow?
Predicting a puppy's adult size can be a mystery, especially with a hybrid breed like the goldendoodle. However, there are some general guidelines to help you estimate your puppy's future size.
At eight weeks, it's difficult to tell which puppy will be the biggest, but the smallest puppy will likely stay the smallest, and the biggest puppy will likely stay the biggest. Expect mini goldendoodles to weigh 4lbs-9lbs at 8 weeks of age.
A standard goldendoodle will likely weigh 9+ pounds at 8 weeks old, and a medium goldendoodle will probably fall somewhere in the 8-10lb range. Both a medium and standard puppy may weigh 9lbs at 8 weeks old, but the standard puppy will gain weight at a quicker rate.
Most goldendoodles do the majority of their growing in the first six months of life. In fact, many mini goldendoodles reach half of their adult weight by four months. Standard goldendoodles may take a month or so longer to reach that halfway mark.

Goldendoodles typically grow for a longer period of time, especially the larger breeds. A general estimate for standards is to multiply your puppy's weight at 4 months by 2 and add 5-10lbs. This rule may not be accurate for smaller-sized goldendoodles who finish growing at a younger age.
Most Goldendoodles will grow up to be 50-90 pounds heavy and standing 20-26 inches at the shoulder. Females are typically at the lower range of this height spectrum, while males are at the upper end.
When Will My Dog Stop Growing?
Your goldendoodle will stop growing completely after about 16-18 months old.
However, you'll notice a significant slowdown in growth by the time they're around 10 months old. After that, changes in size become less noticeable.
The most growth happens between 2 and 8 months - your puppy will seem to get a bit bigger every single day during that time! It's a fun project to track their growth by taking a picture of your Goldendoodle pup every month.
Dogs can finish growing anywhere between 1-2 years of age, but generally reach their maximum height by a year of age.
Predicting Adult Size
Predicting Adult Size is a bit of a challenge, but there are some general guidelines to help you estimate your F1b Goldendoodle's adult size. Goldendoodles are hybrids, so each puppy's genes will dictate how large or small it will be when full-grown.
You can take a "guesstimate" on your pup's final adult weight based on observed growth patterns. A good rule of thumb is to look at the typical size predictions of Goldendoodles: Toy Goldendoodles usually weigh 10-25 pounds, Mini/Medium Goldendoodles weigh 25-50 pounds, and Standard Goldendoodles weigh 50-90 pounds.
Here's a breakdown of the typical sizes and weights for Goldendoodles:
Keep in mind that these are just general guidelines, and your F1b Goldendoodle's adult size will depend on many factors, including its parents' weight and body type, your lifestyle and exercise routines, and the type of food you're feeding it.
At What Age Are They Full-Grown?
Goldendoodles will take 1-2 years to reach their final size, which can be a bit tricky to predict since they don't grow linearly in weight and height.
Their height will likely be reached by their first birthday, but they'll continue to gain weight after that. Some dogs will even "drop their chest" and appear more muscular, especially if they're not spayed or neutered.
The "filling out" process can vary depending on several factors, including the parents' weight and body type, your lifestyle and exercise routines, and the type of food you're feeding your growing Goldendoodle.
Here are some key factors that can influence your Goldendoodle's adult size:
- Parents' weight and body type (lean, big-boned, muscular etc.)
- Your lifestyle and exercise routines (dogs that get a lot of exercise will get leaner and more muscular than couch potato dogs)
- The type of food you are feeding your growing Goldendoodle
DNA Test Predicts Puppy's Adult Size
DNA tests can predict your puppy's adult size, but it's not a guarantee. Embark, a canine genetic testing company, offers a test that looks at the genes affecting a dog's body size blueprint.
This test is way more scientific than simply guessing by the size of your puppy's feet. You can order an Embark testing kit off Amazon, send in a cheek swab, and get the results.
