Many new Goldendoodle puppy owners will usually wonder when is a Goldendoodle full grown. This is because Goldendoodles grow at an extremely fast rate for the first 11 months of their life. New dog owners usually panic that their dog is going to be bigger than expected and want a simple way to calculate their future weight.
Predicting when your Goldendoodle is full grown isn’t too difficult as they typically follow a growth curve. You can also usually predict how much your Goldendoodle will weigh by the time they are a full grown adult within 10 pounds or so. However, there is a lot of variances because Goldendoodles are a crossbreed dog.
In general, a Goldendoodle will be full grown at approximately 12 months or 52 weeks. At 12 months old, your Goldendoodle will be approximately 97% of their total body weight which will consider that to be full grown. Over the course of their life, they will gain a little more weight and fill out, but they will be fully grown and the growth curve will start to level off. You can check out our Goldendoodle weight graph below. If you want to genetically test how big your Goldendoodle will get, we highly suggest you check out Embark DNA Tests.
Estimating the Weight of Your Full Grown Goldendoodle
|Age in Weeks||% of total size|
You can estimate the weight range of your Goldendoodle with the following chart. The formula is Your Goldendoodle’s Weight x (100 / % of total size in weeks].
So if my Goldendoodle is 10 pounds at week 12, then his approximate weight is going to be 10 x [1+ (100 / 40.51)] = 24.68 pounds
This data was taken from the growth chart of several Goldendoodle puppies until they were full grown. It does tend to slightly underestimate the weight of your dog if you are expecting to have a standard-sized Goldendoodle. This is because the sample set was taken from many mini Goldendoodle and medium Goldendoodle owners. Weight is always an approximation and some dogs can hit their growth spurt earlier than other dogs.
Estimating your Goldendoodle’s Weight with a DNA Test
If you don’t feel like doing math and want a more precise answer on how big your Goldendoodle will get when they are an adult, you can always get a DNA test. The Embark DNA Test will not only tell you how big your dog will get, but it will also tell you all of the health risks, your dog’s breed, and you can figure out their relatives. We bought the Embark DNA Test for our Goldendoodle and we found it was very accurate.
All we had to do was swab the cheek of our dog and send it in. The results came with a couple of weeks.
Goldendoodle Weight Chart
In general, there are three different sizes of Goldendoodles. The three main sizes are the mini, medium, and standard size Goldendoodles and they follow typically follow this growth curve. We plotted the average weight in pounds versus the number of weeks a Goldendoodle was. The growth curve sample was taken from several different Goldendoodle dogs.
As a general rule of thumb at Week 8 when you pick up your puppy:
- Mini Goldendoodles will be 3 to 9 pounds. The weight range is significant for mini Goldendoodles because there are micro, petite, and teacup sizes that offset the weight of this category.
- Medium Goldendoodles usually range from 8 to 10 pounds.
- Standard Goldendoodles usually range from 10 to 20 pounds.
For the purpose of this chart, we are assuming a full grown mini Goldendoodle will be 30 pounds, a full grown medium Goldendoodle will be 45 pounds, and a full grown standard Goldendoodle will be 60 pounds.
As you can see, a Goldendoodle’s weight tends to grow extremely fast until around week 52 (1 year), at which point they will be 97% of their total body weight. A more helpful graph is below that plots the total size versus the weight of a Goldendoodle dog.
Goldendoodle Growth Chart
The Goldendoodle growth chart was taken from data received from several pet owners. It was then normalized to create this Goldendoodle growth chart.
Most Goldendoodle puppies are picked up at week 8. When they are picked up at week 8, they are already 29.88% of their total body weight. You can get a general range of how much your Goldendoodle is going to weigh to multiplying their weight at week 8 by approximately 4. So if you pick up your Goldendoodle and they weigh around 9 pounds, you will likely have a full grown Goldendoodle that weighs 36 pounds.
At week 12 (or 3 months old) is already 40% of the total growth they will see in their life. If you take your Goldendoodles weight at week 12 and multiply by 3x then that will be a rough estimate of their full grown weight.
By week 16 (or 4 months old), your Goldendoodle is going to be approximately half of its weight. You can multiple their weight by 2x to get an approximate weight range. Remember, a Goldendoodle’s growth is exponential until around 7 to 8 months old.
By week 24 (6 months old), your Goldendoodle is going to be approximately 74% of their total weight. If you multiply 1.26 * [weight of your Goldendoodle] you’ll get an approximate future weight of your dog.
At week 32 (8 months old), your Goldendoodle’s growth should have started to slow down. They won’t be gaining tons of weight each week as compared to the first 7 months. A Goldendoodle is approximately 86% of its body weight. So if you take your dog’s weight and multiply by 1.14 then you will get an approximate weight when they are an adult.
At week 40 (10 months old), your Goldendoodle is 90% of their total growth! Only 10% more to go until they are fully grown. If you take their current weight at 10 months old and multiply by 1.10 then that’s the approximate adult weight of your Goldendoodle.
By week 52 (1 year old), your Goldendoodle is going to be 97% of their total body weight. You can assume that they will only gain a few more pounds over the course of their life. Your Goldendoodle is full grown!
Conclusion for When is a Goldendoodle Full Grown?
We’ve looked at the data and can conclude that your Goldendoodle will be about 97% of their total body weight at the 1-year mark. Their weight tends to significantly level off after they are 1 year old, so we will consider the 1-year mark when your Goldendoodle is full grown.
