When is a Goldendoodle Full Grown?
Many new Goldendoodle puppy owners wonder, “when is a Goldendoodle full grown?” Often, this is because Goldendoodles grow extremely fast for the first 11 months of their life. New dog owners usually panic that their dog will be bigger than expected and want a simple way to calculate their future weight.
Predicting how big your Goldendoodle will get 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 are many variances because Goldendoodles are crossbred dogs.
Generally, a Goldendoodle will be fully grown at approximately 12 months or 52 weeks. At 12 months old, your Goldendoodle will be approximately 97% of its total body weight, which will be full-grown. Throughout their life, they will gain a little more weight and fill out, but around one year, they will be fully grown, and the growth curve will start to level off. You can check out our Goldendoodle weight calculator 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 |
| 4 | 20.93 |
| 8 | 29.88 |
| 12 | 40.51 |
| 16 | 53.47 |
| 20 | 65.44 |
| 24 | 74.42 |
| 28 | 81.40 |
| 32 | 86.05 |
| 36 | 90.70 |
| 40 | 93.02 |
| 44 | 95.35 |
| 48 | 95.81 |
| 52 | 96.28 |
| 56 | 96.74 |
| 60 | 96.98 |
| 64 | 97.21 |
| 68 | 97.44 |
| 72 | 97.67 |
| 76 | 97.91 |
| 80 | 98.14 |
You can estimate the weight range of your Goldendoodle with the following chart. The formula is Your Goldendoodle’s Weight x (100 / % of the 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 whose size and weight were tracked until they were fully grown. It tends to slightly underestimate your dog’s weight if you 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; some dogs can hit their growth spurt earlier than others.
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 your dog’s health risks, your dog’s breed, and you can figure out their relatives. We bought the Embark DNA Test for our Goldendoodle and found it very accurate.
All we had to do was swab the cheek of our dog and send it in. The results came within a couple of weeks.
Goldendoodle Growth Chart
We gathered data from several pet owners to create the Goldendoodle growth chart above. We then normalized the data to create this Goldendoodle growth chart for all sizes of Goldendoodles.
Most owners pick up their Goldendoodle puppies at Week 8. When picked up at Week 8, they are already approximately 29.88% of their future full-grown body weight. You can get a general range of how much your Goldendoodle will weigh by multiplying their weight at Week 8 by 4. So if you pick up your Goldendoodle puppy 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), they have already undergone approximately 40% of the total growth they will see in their life. If you take your Goldendoodle’s weight at Week 12 and multiply it by 3, that will be a rough estimate of their full-grown weight.
By Week 16 (or 4 months old), your Goldendoodle will be approximately half of its future full-grown weight. You can multiply their weight by 2 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 will be approximately 74% of its future fully grown 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 slowed down. They won’t be gaining much weight each week compared to the first 7 months. A Goldendoodle is approximately 86% of its future body weight at Week 32. So if you take your dog’s weight and multiply it by 1.14, you will get an approximation of their future adult weight.
At Week 40 (10 months old), your Goldendoodle is at 90% of its total growth! Only 10% more to go until they are fully grown. If you take their current weight at 10 months old and multiply it by 1.10, then that’s the approximate adult weight of your Goldendoodle.
By week 52 (1 year old), your Goldendoodle will be 97% of its future total body weight. You can assume they will only gain a few more pounds throughout their life. Your Goldendoodle is fully grown!
Goldendoodle Weight Chart
In general, there are three different sizes of Goldendoodles: mini, medium, and standard. All sizes typically follow this growth curve. In the weight chart above, we plotted the average weight in pounds versus the age (in number of weeks) of the Goldendoodle. The growth curve sample represents several different Goldendoodle dogs.
As a general rule of thumb, at Week 8, when you pick up your puppy:
- Medium Goldendoodles will usually range from 8 to 10 pounds.
- 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.
- Standard Goldendoodles will usually range from 10 to 20 pounds.
For this chart, we assume 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.
How To Care for a Growing Goldendoodle Puppy?
A growing Goldendoodle puppy needs proper nutrition and care to develop. Without adequate calories and nutrients, a puppy will experience growth issues and may have health problems down the road. Without adequate exercise, a puppy won’t learn how to tire itself out or how to settle or soothe itself.
Nutrition
Talk to your vet about the right food to feed your puppy, and about the right amount to feed it. Buy food recommended by your vet or that meets or exceeds AAFCO standards. Many foods are specifically developed for small or large-breed puppies at each stage of development.
Refrain from feeding your puppy a lot of additional snacks, treats, supplements, and vitamins. Unless recommended by your vet, supplements and vitamins are not necessary for healthy growth. Treats should be used for training only, and you should avoid foods high in carbohydrates or fat.
Exercise
Without exercise, your puppy will drive you crazy. Exercise is good for dogs of all ages and especially important for puppies who need to burn off excess energy.
Take care not to overexert your puppy. Most vets recommend that you do not do strenuous activities with your dog until their bones have finished growing. Avoiding overexertion is particularly important for large dog breeds that can end up with joint problems later in life.
If you want to take your Goldendoodle running or biking, make sure to talk to your vet first. Your vet will most likely recommend that you wait as long as two years before doing this, to give your puppy a chance to finish growing.
Frequently Asked Questions
How big is a full-grown Goldendoodle?
Mini Goldendoodles full grown are 30 pounds. Medium Goldendoodles full grown are around 45 pounds. Standard Goldendoodles full grown are usually around 60 pounds.
How big is a full grown mini Goldendoodle?
According to breeders a full grown mini Goldendoodle should be between 26 to 35 pounds and 14 to 17 inches tall at the shoulder. But people reported that their “Mini” Golden doodle ranged anywhere between 15 to 35 pounds when full grown.
As I pointed out above the doodle generation will have an effect on the size of your Goldendoodle. Later generations will have more consistency in size than first generation mini doodles.
How big is a full grown Goldendoodle?
Breeders state that a standard Goldendoodle will be 50 or more pounds and 21 inches or taller at the shoulder when fully grown This matches the data collected from Goldendoodle owners who reported weights between 50 and 110 pounds for their adult Goldendoodles.
How can I most accurately predict the fully grown weight of my Goldendoodle?
There are two ways to do this. The first is to get a DNA test. We recommend the Embark DNA Test. The second way is to talk to the breeder of your Goldendoodle puppy. The breeder can use the size and weight of the parent dogs and their years of breeding experience to predict the fully-grown weight of your Goldendoodle puppy.
Mini Goldendoodle weight: when do Mini Goldendoodles stop growing?
Mini Goldendoodles will be fully grown around 1 year. They will fill out in weight and stop growing around the 2-year mark.
How big is a fully grown toy Goldendoodle?
The Goldendoodle Association lists a petite Goldendoodle as their smallest size. This size range includes the toy, Micro mini and teacup Goldendoodles. Breeders state that a petite Goldendoodle is under 14 inches tall and weighs less than 25 pounds.
When do Goldendoodles stop growing?
A Goldendoodle usually stops growing around the 2-year mark. They usually gain almost all their weight within the first year and only gain a small amount until they are 2 years old.
Are male Goldendoodles and female Goldendoodles full-grown at the same time?
Yes, both male and female Goldendoodles are considered fully grown when they are 1 year old. However, there is some variation in how big they get. Like most dog breeds, a male Goldendoodle weighs more and is taller than a female Goldendoodle by around 10% of its total body weight.
Why is it hard to create a precise Goldendoodle weight calculator?
Goldendoodles are a crossbreed between two breeds: a Golden Retriever and a Poodle. Because Goldendoodles aren’t a true “breed,” they aren’t held to specific breed standards like purebreds. This intentional breed mix often means you get the best of both breeds; however, this comes with more variation in traits such as height and weight. This isn’t a bad thing! Our article above can give you approximate ranges for the predicted height and weight of your future fully-grown Goldendoodle. These ranges will still give you a pretty good idea of how big your Goldendoodle will get.
Final Thoughts
We’ve looked at the data and can conclude that your Goldendoodle will be about 97% of its fully grown body weight at the 1-year mark. Their weight tends to level off around their first birthday, so we will consider the 1-year mark when your Goldendoodle is fully grown.
