How big will my Labradoodle get?

Size is largely determined by genetics. While environmental factors such as the type of food you feed or the time of a spay/neuter surgery can have a small impact on your Labradoodle’s adult weight, it will mostly be set by his genes.

Size is inherited in non-linear ways in dogs (and other animals). You cannot simply assume that your puppy is going to be the average of both parents’ weights. Some puppies stay much smaller than both parents, some become much bigger, and some are in the middle. 

While size is already hard to predict in purebred dogs, it becomes even more erratic when two breeds are crossed such as in any Doodle mix litter. Labradors are large dogs. They can have a heavy build with deep chests and a wide rib cage. Poodles on the other hand are rather dainty, even though they are tall.

Especially in the first generation of a Labradoodle litter (that means a generation whose parents are a purebred Poodle and a purebred Labrador), there will be a greater variation of size. The smallest and the tallest puppy of the litter might be as much as 20 pounds apart in weight!

That being said, most Labradoodles weigh somewhere between 45 and 65 pounds and are 22-24 inches tall. Because they are a mixed breed, they are not recognized by the American Kennel Club and have no breed standard that requires a certain size. Your dog’s color has nothing to do with his size by the way: A black Labradoodle will grow just as tall as a white one.

At what age is a Labradoodle fully grown?

As a large dog breed, Labradoodles grow past their first birthday. The smaller a dog, the sooner he is finished growing. Some very small breeds can stop growing around 8-10 months. Since the Labradoodle is tall, expect him to continue growing until about 12-18 months of age. Even past this time, he will continue to “fill out” – meaning the chest may get a bit deeper and your dog will gain muscle mass.

At 12 months, most tall dogs are lanky teenagers! By the time your Labradoodle is 2 years old, he will definitely be done growing.

How big is a 6 month old Labradoodle?

At 6 months old, your Labradoodle will weigh about 25-35 pounds. He is definitely not fully grown yet – expect him to become quite a bit taller and heavier in the coming months.
If your Labradoodle is significantly lighter or heavier, do not panic: It might be that he either inherited a lot of the Labrador parent’s size, or that the genes of the lean Poodle are strong. If your Labradoodle’s parent was a Miniature Poodle, he will of course be quite a bit smaller.
As your Labradoodle puppy is growing up, his coat will become longer and thicker as well! Make sure you bathe and brush him regularly

Trimming his coat regularly with a good set of clippers will be very important as well!

Ensuring healthy growth

Here is what you can do to set your Labradoodle up for a healthy growth and solid adult weight:

Nutrition and feeding

Without the right nutrition, your pup cannot grow well. You need to feed your Labradoodle a high-quality food with a lot of protein. Protein is what our bodies are built of – your growing pup needs a lot in order to grow tall and strong.

You can choose from a variety of different foods, such as:

  • Dry food
  • Wet food
  • Dehydrated food
  • Raw food
  • Premade raw food

Or any combination of those!

You should absolutely refrain from cooking your dog’s food yourself. Dogs’ nutritional needs are very different from humans’ and they do not do well on a diet of e.g. chicken, rice and carrots. Your dog needs different muscle and organ meat, and not as many carbohydrates as we tend to eat.

In the beginning, feed your Labradoodle 4 times a day for optimal growth and development. Once he is about 4 months old, you can switch to 3 daily feedings. Around the first birthday you can cut this down to two meals if you would like.

However, there is no inherent benefit in only feeding your dog twice a day, and most Labradoodles do best with three smaller meals. This is due to the fact that they are usually very food-motivated and might scarf down the food if they are not fed several times a day, risking bloat.

Slow feeding bowls can help with that!

Labradoodles, like all Doodles, tend to be very mouthy as puppies. Provide plenty of appropriate chew items to reduce the tendency to chew and bite.


In order to help your puppy develop coordination and balance skills as well as build muscles, he needs daily exercise. While you should never force your puppy to participate in any kind of sustained high-impact exercise (such as jogging with you on asphalt), it is crucial that he gets to run and play on soft ground every day. Dogs that are not exercised sufficiently experience stunted growth, become less strong and suffer from a weak immune system.
