Goldendoodles have become one of the most popular dog breeds.

This cross between a standard Poodle and a Golden Retriever is known for its good-natured intellect and hypoallergenic tendencies, making it a perfect choice for families. If you've recently acquired or plan to acquire a Goldendoodle puppy, you'll want to know the requirements in terms of size and growth requirements.

From the time they are born until they are nearly two years old, all Goldendoodle puppies go through seven major growth stages. We will take a deeper look at those stages of development to get a better idea of what to anticipate as your Goldendoodle matures.

You are not alone in wondering when a Goldendoodle is full-grown. The type of Poodle utilized during breeding has a significant impact on the size and weight of a Goldendoodle in adulthood.

Small and medium-sized pups reach their adult size in half the time it takes a larger breed. There is so much to know and learn about these adorable breeds of dogs and their multiple sizes!

What is a Goldendoodle's growth cycle?

A Goldendoodle may attain full size before the age of a year, based on its parents. It is preferable if your puppy was at least the age of eight weeks when you got them home.

We'd like to know how big a full-grown Goldendoodle is? Broadly full-grown mini Goldendoodles weigh about 30 lbs (13.6 kg), full-grown medium Goldendoodles are around 45 lbs (20.4 kg), full-grown standard Goldendoodles usually are about 60 lbs (27.2 kg). You might question, when do Goldendoodles stop growing?

It appears that they are merely cute small puppies for a brief period of time. The average Golden Retriever stands between 21 to 24 in (53.3-61 cm) tall at the shoulder and weighs between 45 to 70 lbs (20.4-31.7 kg). Female Golden Retrievers are often smaller than male Golden Retrievers.

A Golden Retriever is fully grown at two years of age. There are many sizes of  Goldendoodles due to the varying sizes of Poodles. So let's take a closer look at each of them.

To decide the weight of your Goldendoodle, you need to follow the span of the dog in weeks and get the average weight of your dog. For instance,  when your mini Goldendoodle is 12 weeks old, it should measure around 12 lbs (5.4 kg).

Your puppy should reach roughly 27 lbs (12.2 kg) when it is 36 weeks old. The mini Goldendoodle, is classified as a small breed dog.

Between six and eight months, they will attain adult height.

A miniature Goldendoodle is a hybrid between a toy or miniature Poodle and a Golden Retriever. They can be a mix between a toy or miniature Poodle that weighs less than 35 lbs (15.8 kg) and a standard or mini Goldendoodle.

They grow to be 17-20 in (43.1-50.8 cm) tall and weigh 40-50 lb (18-22.6 kg) on average. Smaller dogs mature more quickly than bigger breeds.

A mini Poodle will grow as big as it will ever become by six to seven months old. Therefore six to seven months old, a mini Poodle will be the tallest it will ever be.

However, most mini Poodles appear to be fully grown, mainly by ten months old. The Toy Goldendoodle dog is the smallest of the three sizes, measuring 13-20 in (33-50.8 cm) tall and 15-30 lb (6.8-13.6 kg) of weight.

Medium Goldendoodles will, by definition, be larger than miniature Goldendoodles. At 12 weeks of age, your medium Goldendoodle dog weighs roughly 20 lb (9 kg), indicating that they are already much larger than the minis.

A medium Goldendoodle will reach around 40 lb (18.1 kg) on average at 36 weeks. However, these are averages, and the weight of your dog may vary somewhat.

You don't have to be concerned as long as your dog follows his natural growing pattern. The parents' height is more important than picking a particular-sized Poodle to mix within the medium Goldendoodle.

When your puppy reaches around a year old, you may expect them to mature into adults. Toy and mini Goldendoodles will have grown to adult size by the time they're a year old.

Finally, standard Goldendoodles are the most common of all the Goldendoodle breeds. You can anticipate your standard Goldendoodle to weigh 30 lbs (13.6 kg) by the time it is 12 weeks old.

Your puppy should weigh roughly 55 lbs (25 kg) at 36 weeks, demonstrating how large these dogs are. A standard Goldendoodle grows to be 20 to 24 in (50.8 to 61 cm) in height and weighs between 50 to 90 lbs (22.6 to 40.8 kg). They're a cross between a Golden Retriever and a Standard Poodle.

As both the dogs, Golden Retriever and a Standard Poodle, develop at the related rates, a standard Goldendoodle dog will. These results are consistent across the board because the standard Goldendoodle has no unique genetic features. Therefore, you can anticipate these dogs reaching their maximum height at a year old and highest weight by two. 

When do Goldendoodle puppies stop growing?

Goldendoodle puppies have weight roughly a pound at birth. The weight of puppies will double in the first two weeks of life. You can't use a dog's birth weight to reliably predict its adult weight because of weight variations after birth. 

You should expect a significant growth spurt between the ages of three and 12 weeks for your Goldendoodle puppy. In a short period of time, the puppies will go from scarcely moving to running around like crazy.

Puppies weigh only a few pounds at three weeks of age, but by the time they are 12 weeks old, they can weigh up to 25 lbs (11.3 kg). Their appetite will also increase, necessitating a lot more puppy food.

Your puppy will grow a lot more and have a bigger appetite between the ages of four months (16 weeks) to six months.

By the time he's six months old, your puppy should weigh roughly 45 lb (20.4 kg). This is also towards the end of his most spectacular growth spurts, so his growth will slow down, as will his appetite.

At seven months of age, your Goldendoodle puppy will weigh about 50 lb (22.6 kg), increasing to about 55 lb (25 kg) in nine months. At this stage, his weight increase should be slowing down significantly.

At this stage, he should only be eating two meals per day, but you should still be providing him puppy food. When your Goldendoodle reaches ten months of age, its growth will have slowed significantly.

By that time, he should be roughly 60 lb (27.2 kg). His hunger should have slowed, and you should keep feeding him puppy food until he turns one year old, at which point you can begin to transfer him to adult dog food.

Mini Golden Doodle Size Vs. Normal Golden Doodle

The final weight of an adult Goldendoodle varies greatly depending on the dog and the kind of Goldendoodle. The standard Goldendoodle can grow up to 90 lb (40.8 kg), but it can also be much smaller.

During the 40-week to one-year period, smaller Goldendoodle puppies may stop growing. Although standard Goldendoodles will stop growing in height, they will continue to fill out for a few months longer.

You can even get a DNA test done to assist you in figuring out how much your dog will have weight when he's finished growing. You should be able to track your dog's growth chart to get an estimate of where your dog will finish up in terms of weight.

Dogs, like people, have a predictable growth pattern. Because Goldendoodles are a mixed breed, calculating their growth rate is difficult.

Your Goldendoodle may be more like the larger parent or the smaller parent. And there's no way to tell until they're a few months old.

The first and most popular combination is a Toy Poodle father with a Goldendoodle mother. This Goldendoodle, on the other hand, is a complicated combination.

They are a mix of Golden Retriever, mini Poodle, with Cocker Spaniel to make them shorter than a mini Goldendoodle. A Toy Poodle with mini Goldendoodles is the second combo. They usually reach their maximum height and weight at six to seven months and one year.

Does their diet affect their size?

Various factors impact the size and growth of your dog.

If not fed properly, then they will not grow to their full size. They will also be prone to health problems.

To begin with, all Goldendoodles will reach a point where they will stop growing at various ages. In general, the dog should be full-grown around the age of one and a half years.

These dogs may achieve their full size sooner, perhaps around 12 months, but they must gain weight for at least a year and a half. They will take longer to achieve their full size, unlike smaller dog breeds because they are huge dog breeds.

For the first six months and a year of their life, Goldendoodle puppies grow rapidly. Because standard Goldendoodles have more growth than mini or Toy Goldendoodles, growth spikes are more obvious.

We can easily predict how much weight our Goldendoodle will gain when fully grown with the guidance of a Goldendoodle puppy growth chart! You may observe that Goldendoodles go thru growth spurts before they stop growing.

A puppy's most remarkable development occurs between the ages of birth and six months. Your puppy will not only appear to treble in size during these development spurts, but they will also undergo other changes.

Goldendoodles are a beautiful breed of dog to own, but these dogs do have the due proportion of health issues. Almost every dog breed has a health issue that owners must be aware of.

You must be very careful with food because it has a significant impact on the development of your doodle. Even if your pet has grown to adulthood, you must continue to feed it puppy food. It's recommended to take your doodle to the veterinarian if you're not sure if they've reached adulthood.
