When Is A Golden Retriever Full-Grown?

When Is A Golden Retriever Full-Grown?

If you just got yourself a Golden Retriever puppy, then you have an exciting time ahead of you.

During their development into an adult dog, Golden Retriever puppies have a lot of learning and especially growing to do. But how long does it take for a Golden Retriever to be fully grown?

In this article, we’ll dive into everything you need to know about a Golden Retriever’s growth and development. On top of that, we’ll also give you insights into Golden Retriever size and weight. In that way, you can determine whether your Golden Retrievers are on the right track to becoming healthy adult dogs.


When Do Goldies Stop Growing?

If you are wondering, “when will my Golden Retriever stop growing?”, the answer is at around the 12 months mark. This, however, doesn’t mean that they have reached their adult weight yet, which only happens at around 18 months of age.

Just because your Golden Retriever has stopped growing doesn’t mean that it is fully mature, though. It usually takes up to two full years for Golden Retrievers to reach full mental maturity. You can still expect your full-grown Golden Retriever to behave like a stubborn teenager every now and then!


When Do Golden Retrievers Become Adults?

To turn into full-on adult dogs, Goldies can even take longer than two years.

Generally, Golden Retrievers take about three years to become adults. Each dog is an individual, so some can mature faster while others might take a bit longer.

If you’re concerned about your dog’s weight or mental development at any stage, always consult with a certified veterinarian.


How Much Should A Golden Retriever Puppy Weigh?

Since each puppy is sized differently, it’s really hard to give a definitive answer to this question.

There can be wide variations when it comes to the rate of each puppy’s growth, especially between male and female Goldens.

As a general average, most Golden Retriever puppies bulk up 1.5 pounds for every week of age. We’ll walk you through the general average Golden Retriever puppy weight below.

Puppy growth chart and development stages

There are several development stages your Golden Retriever pup will go through until they reach physical and mental maturity.

Here is the puppy growth chart from eight weeks onward:

  • 8 weeks – 10 pounds
  • 9 weeks – 12 pounds
  • 10 weeks – 15 pounds
  • 11 weeks – 17 pounds
  • 3 months – 22 pounds
  • 4 months – 30 pounds
  • 5 months – 40 pounds
  • 6 months – 44 pounds
  • 7 months – 48 pounds
  • 8 months – 55 pounds
  • 9 months – 57 pounds
  • 10 months – 62 pounds
  • 11 months – 65 pounds
  • 12 months – 68 pounds

While they grow, they also go through special developmental stages where they will reach certain behavioral milestones and require different types of training and care.

Puppy development stages:

  1. Neonatal

This stage begins from birth until your puppy is around three weeks of age.

In this stage, all puppies are practically helpless and rely heavily on their mother to feed them and keep them warm and clean.

Their eyes slowly begin to open, and their first teeth push their way through. Some might start crawling slowly and wobble around, trying to walk for the first time.

Generally, Golden Retriever puppies will weigh less than five pounds during this stage.

  1. Socialization

During the first twelve weeks, your Golden puppy will start to explore the world around them. They remain reliant on their mother but can begin eating solid food and getting more explorative.

At this stage, it’s a good idea to start introducing the puppies to other people and animals slowly so they will be more social as adults.

As they begin to control their bowel movements and bladder, you’ll need to begin house training.

Remember, your pooch needs to go for its first round of vaccinations between six and eight weeks of age!

  1. Juvenile

From three to six months onward, your Golden Retriever puppy’s growth spurt will slow down a little. They become smaller versions of the adorable adult dogs they’ll eventually grow into.

The most remarkable changes to notice are:

  • Loss of baby teeth and growth of adult teeth
  • Separation from their mother
  • Responding well to training

You should take your Golden Retriever to get spayed or neutered at around six months unless you are considering breeding with it.

  1. Sexual Maturity

From six months old until about 16 months, most Retrievers are on their last growth stretch and developing into their final and full size.

If you didn’t neuter them, they will reach sexual maturity at around the six-month mark and will start displaying mating behavior during their first heat cycle.

This hormonal rush can also lead your Golden Retriever to become more stubborn or even start to challenge you as a means of figuring out its place in the family/pack.

At the start of this period, your dog might look a little disproportioned. Goldens can have weirdly long legs and long floppy ears that make them look quite goofy. But don’t worry – they will grow into them over time!

Note that because of their last growth spurt, their bones and joints are more vulnerable than usual. Be careful with the amount of exercise and pressure you put on their joints at this stage. For example, avoid big jumps and lots of stairs.

  1. Adulthood

At about 16 months of age, Goldies typically reach adulthood. Some might still have some growing to do, but in general, your puppy will have reached its growth end stage.

A male Golden Retriever will be between 23 and 24 inches tall, while a female Golden Retriever will be slightly smaller at about 21.5 to 22.5 inches tall.

Note that while they will stop growing in size at this stage, your Golden Retriever will still pack on some weight after this point. This is a good thing, as the Golden Retriever breed tends to look a bit lanky for its frame at around 16 months old.

Another very important thing to remember at this stage is that although your Golden Retriever will look like an adult, it will still carry some of the puppy traits with it for some time. Don’t expect a 16-month-old Golden Retriever to act like the most mature dog just yet!

If you, at any of these stages, feel that the Golden Retriever puppy growth is abnormal, or too slow, speak to your vet and have it checked out.


Golden Retriever Growth Chart

A male Golden Retriever generally has an adult weight of between 65 and 75 pounds and stands from 23 to 24 inches tall.

Females tend to be not as big, with an adult’s weight between 55 to 65 pounds. They will grow 21.5 to 22.5 inches tall on average.

The Impact Of Food On Golden Retriever Growth

The food that you choose as a Goldie owner has a significant effect on the growth and development of your dog.

How much and what kind of food you choose can either lead to stunted or accelerated growth. Choosing a balanced and nutritious diet will be the best to ensure healthy growth and a decent weight range.

But how can you ensure that puppy growth is right on track? While puppies inherit physical traits from their parents and will, therefore, slightly differ in size and weight, the weight chart and information on how many inches tall your puppy should be at a certain stage in their life is a good way to figure out if you are doing the right thing.

But don’t try to overfeed your dog as a way to accelerate its growth. This can lead to unhealthy weight gain and potentially pose a serious health risk to your dog.

Tips on healthy Golden Retriever puppy growth

In order to make sure Golden Retriever size remains healthy and appropriate, we’ve put together a few tips and tricks on how to ensure they reach a healthy adult weight.

  1. The right diet

The best way to figure out the correct diet for your dog is by speaking to your vet about the different food you should feed the different Golden Retriever size stages.

Always check whether the food you have chosen is right for your Golden puppy’s life stage. Don’t feed a 6-week-old Golden Retriever food that was made for adults and vice versa.

Certain diets also have special functions for healthy Golden Retriever growth. In this instance, feeding salmon is great for an old Golden Retriever as well as a Golden puppy, as the Omega-3 fatty acids are really good for joint health.

  1. The right exercise

Regular exercise is absolutely fundamental to ensure Golden Retriever weights stay within healthy boundaries. You should also ensure that the exercise is specially designed for the age of your Golden Retriever.

For instance, you should never let a six-month-old Golden Retriever put too much pressure on its bones and joints as it is going through a growth spurt.

  1. Vaccinations

Vaccines help prevent diseases that can affect Golden Retriever growth and size.

Speak to your vet and figure out which vaccinations are necessary for your dog and your area.



My 24-month-old Golden Retriever is not fully grown yet. Is something wrong?

If your mature Golden Retriever’s size doesn’t seem to be appropriate for its age, don’t worry immediately. The chances are high that there is absolutely nothing wrong with your dog.

Lots of Golden Retriever puppies take time to reach adult weight. And there are many factors involved when it comes to a dog’s development.

As long as your dog is being fed a healthy diet and has been showing healthy growth, don’t worry. It will probably just need a little more time to get there.

At what age your Golden Retriever should reach adult weight and size can be determined by your veterinarian. Therefore, we always suggest consulting with your personal vet. They will know the dog best and can figure out if there is any problem.

Is my Golden Retriever puppy too fat or too thin?

If you’re wondering about your dog’s weight and whether it is too fat or too thin, we recommend checking our growth chart.

Here are some other ways to determine whether your dog is too fat:

  • You should see a noticeable waistline when you look down on your dog.
  • You should feel your dog’s ribs with gentle pressure.

A way to tell if your dog is underweight is if you can see its ribs.

Obesity can be a big problem for many breeds, so it’s important to know what to feed your dog. It’s best not to give them too many treats and regular exercise is a must.

Unfortunately, more than half of Golden Retriever adults are considered obese or overweight. So, make sure your dog gets enough exercise by walking it daily and always feed it the appropriate amount of food.

How do I make my Golden Retriever pup bigger?

As we’ve already stated in this article, you shouldn’t attempt to accelerate puppy growth.

Overfeeding will simply lead to obesity and could damage your dog’s joints. You can end up with a dog suffering from elbow or hip dysplasia. This is a painful condition that can affect your pup’s quality of life.

If you decide to neuter your dog while it is still young, you could cause it to grow taller. Sex hormones have a special impact on the development of your dog. We recommend not neutering your dog earlier than 6 months, as this can lead to other abnormalities.

How do I know how big my Golden Retriever puppy will become?

If you want to know the adult weight and size of your Golden Retriever, it’s best to look at its parents. A Golden Retriever puppy will rarely grow taller than their parents.

What is the biggest Golden Retriever?

When it comes to which adult Golden Retrievers are the biggest, the Canadian Golden Retriever is definitely leading the pack. While there isn’t an immediately noticeable difference, the Canadian Golden is about two inches taller than English or American Goldies.

What you will notice is that the body structure of Canadian Goldens differs from others. They appear a lot bulkier and might pack on a bit more adult weight than their counterparts.

Does the size of my Golden Retriever affect its lifespan?

There is a general rule in the canine world that states that the larger the dog breeds, the shorter the lifespan. This certainly holds true for a Golden Retriever’s life as well.

A number of factors contribute, but mainly, large dogs tend to age more quickly than small dogs.

The adult weight of your Golden Retriever does also play a significant role in how old it might get. Therefore, it is so important to feed your dog a healthy diet to make sure it leads a long and healthy life.
