Generally, Labradoodles are completely grown by one year or 12 months old. At this point, they mostly stop growing.   

We delve deeper into the growth of Labradoodles below. Keep reading to find out all about Labradoodle sizes and growth rates.

The Size of Your Labradoodle Depends on Its Age

By 12 months or 52 weeks, a Labradoodle reaches about 97 percent of its total body weight at its adult dog stage. By that time, your dog would have reached its final height. As for its weight, it might take a few more weeks for your dog to add those last few pounds and reach 100 percent of its total body weight.

When you first bring your puppy home, he might be only eight weeks old and reach about 30 percent of its final body weight. You can expect your pup to get to 75 percent of its final size by 24 weeks.

How To Tell When the Labradoodle’s Full Grown?

You can find out when your canine is fully grown by considering its family history and genetics. How big are your dog’s parents? That will give you an idea of the final size your puppy will reach upon adulthood.

Usually, Labradoodles come in three sizes known as:

  • Mini Labradoodles
  • Medium Labradoodles
  • Standard Labradoodles

Furthermore, the size of your dog will depend on its gender. Male Labradoodles are about 5 percent larger than the female breed on average. Often, DNA testing is the best way to get an accurate idea of how big your dog will get.

DNA Testing

Ask your vet to perform a DNA test on your pup if you’re concerned about its adult size. You can also get a DNA home testing kit to determine size. The Embark dog DNA test kit tends to have the most accurate results and has high ratings.

With DNA testing, you will also gain more information on your pup’s health risks, breeding, and family history.

The steps for DNA testing are simple. Your pup needs to undergo a cheek swab, and then you can mail in the DNA. You will get results back to you in about two to four weeks.

How Big Do Mini Labradoodles Get?

Miniature Labradoodles are usually around 30 pounds in weight once they are fully grown into the adult stage. By 14 weeks, a Mini Labradoodle is often half its fully grown weight and size. However, it does take about one year before it reaches approximately 97 percent of its grown adult size.

The first Miniature Labradoodle came about in the early 1990s when Dr. Kate Schoeffel began breeding the canine into smaller sizes. When taking care of a Mini Labradoodle, get dog food developed specifically for its size. Nonetheless, the smaller size makes the dog more manageable for many families, and the compact breed gets along better with children.

How Big Are Fully Grown Medium Labradoodles?

By eight weeks, Medium Labradoodles tend to reach about 8 to 10 pounds in weight. The medium-sized dog can take more than a year before reaching its full adulthood size. 

Once they reach full adulthood, Medium Labradoodles are 30 to 45 pounds in weight. Female ones tend to reach 17 to 19 inches in height while males are 18 to 20 inches in height. These dogs are fully matured by 11 to 12 months.

Once again, you will need to pick the right dog food to support the growth of the Labradoodle’s size.

What’s the Full Size of Standard Labradoodles?

The full size of Standard Labradoodles tends to vary greatly. You can expect the fully grown standard Labradoodle to weigh anywhere from 60 pounds to as much as 90 pounds. Such large dogs may not fit in with a family with small children.

By eight weeks, these puppies can range from 10 pounds to 20 pounds in weight. You can expect the canine to weigh more than 45 pounds upon reaching adulthood. In height, the dog can range from 17 to 23 inches.

When you first get a puppy of a standard size, you may get worried about its constant growth. You may think the dog will grow out of control and become impossible to manage in adulthood. However, there are simple formulas you can use to figure out the size it will reach.

How To Estimate Your Labradoodle’s Size Before It’s Done Growing?

You can use a few simple formulas to estimate your dog’s size once fully grown. By eight weeks, your puppy has reached around 30 percent of its final weight. As such, you can simply multiply its weight by four and subtract two or three pounds

At around three months, your pup should have reached around 40 percent of its final weight. At this stage, you can multiply its weight by three and subtract a couple of pounds. These two basic formulas will help you determine the size of your canine once grown.

Picking the Right Dog Size for You and Your Family

When choosing the perfect pup for your home and your family, there are many things to consider. You will need to see whether your place can handle a large dog or whether your cramped apartment means only a small canine will work.

Do you have small children or teenagers? That will also determine the size of the dog you choose. Below, we discuss the different issues that will impact the dog size that will work best for you and your family.

Consider the Size of Your Home

Do you live in an apartment or a large three-bedroom house? If you live in a small apartment, a Miniature Labradoodle is the best choice for you. These pups tend to fit well in smaller spaces, unlike their larger counterparts. 

If you live in a two-bedroom townhouse with minimal outdoor space, the Mini Labradoodle is also a good choice.

However, if your house is relatively large, you can choose a larger Labradoodle. The Medium and Standard-sized Labradoodles need a bigger place to play both indoors and outdoors.

Do You Have a Yard?

If you have a yard and it’s a good size, your life can surely support the Medium and Standard Labradoodle sizes. Make sure to add a fence to your backyard in case you don’t have one yet. These dogs can get boisterous, so you will need fencing to keep them safe.

If you have a Mini Labradoodle and no yard to speak of, you will still need to take your dog for long walks and a game of fetch at the local park. To keep Labradoodles from getting bored and destroying your home, make sure they get 30 to 60 minutes of exercise every day.

Do You Have Children?

If you have small children, such as toddlers under five years, you should choose Miniature or Medium-sized Labradoodles. Yet, if you are a parent of teenagers, any size should work well. The standard-sized breeds fit well with older children and teenagers.

If you don’t have children, you don’t need to worry about that factor. In such a case, any size of Labradoodle will work.

Do You Exercise Outdoors?

Do you live an active lifestyle and spend time going on runs or hikes? If you like to exercise outdoors, you should get a Standard-sized Labradoodle to take on jogs. Sometimes, a canine can give you that push you need to go for a run.

However, if you only want to take a few short walks around the neighborhood, you should consider getting a Miniature Labradoodle.
