If you’re thinking of buying a Labradoodle puppy, you’ll want to know the Labradoodle size when fully grown. That’s crucial information, especially if you live in a home with limited space.
But can you accurately predict the size a puppy will grow to be? When do Labradoodles stop growing? What’s the Labradoodle standard size? And, how big do Labradoodles get?
Read this comprehensive guide to find out!
What Is A Labradoodle?
Generally, when breeding Labradoodles, the mother dog is always the largest of the two partners for safety reasons. If the mother is much smaller than the father, she might have difficulty birthing the puppies, which could be dangerous for both parties.
- When the puppy is a 50% mixture of Labrador retriever and Poodle, it’s referred to as an F1 puppy.
- A crossbreed created by mating an F1 Labradoodle with either a purebred Poodle or Labrador retriever is called an F1B Labradoodle.
- F2 Labradoodles are produced when two F1 dogs are crossbred.
- F2B Labradoodles result from mating an F1B and an F1 dog.
- F3 Labradoodles are also referred to as multigenerational. A dog is considered an F3 when its closest purebred Labrador retriever and Poodle relatives are the puppy’s grandparents or from generations preceding that.
Labradoodles come in different sizes. If a Labrador retriever is crossed with a miniature or toy Poodle, you get a mini or toy Labradoodle, whereas a Standard Poodle father will produce Standard Labradoodle puppies.
At the time of writing, there is no official standard for Labradoodle sizes. However, the smaller varieties are the most popular with families looking for the perfect pet since these dogs are suitable for life in an apartment or small home. For that reason, mini and medium-sized Labradoodles are more expensive than Standard Labradoodles.
Why Were Labradoodles Created?
The Labradoodle was first bred in the 1950s, but the breed first gained traction in the late 1980s. Australian breeder Wally Conron bred Labradoodles specifically to produce a light-shedding service dog that would suit allergy sufferers.
Labradors have the perfect temperament and intelligence to work as service animals, but they are prolific shedders. The Poodle is also an intelligent, working breed but has the advantage of having a single, curly coat that barely sheds at all. So, a cross between the two breeds seemed the ideal solution.
Before becoming popular as family pets, the first Labradoodles worked as service dogs for the Royal Guide Dog Association of Australia.
The most popular Labradoodles tend to be the smaller sizes and those with the lightest-shedding coats. Consequently, puppies of those types are the most expensive to buy.
All dogs shed to some degree. However, curly-coated pups generally shed less than those with straighter hair. In the case of Labradoodles, those with fleece or wool coats shed much less than hair-coated varieties.
Labradoodle Puppy Growth Rates
Interestingly, Labradoodle puppies don’t share the same growth rate. For example, Miniature Labradoodles might be fully grown at ten months of age, whereas a medium-sized dog can continue adding weight for over a year.
It’s almost impossible to predict which of the puppies in an individual litter will reach their adult size first or grow the fastest. In some cases, the largest puppy at six or eight weeks of age might finish up being the biggest adult dog, but that’s not guaranteed.
Guide To Labradoodle Sizes
Aside from an occasional genetic quirk and generational throwback, a dog’s size is generally influenced by the size of its parents. So, if you cross a large Labrador retriever with a large Poodle, you will ultimately end up with a full-grown Standard Labradoodle.
A full-grown Standard Labradoodle will be pretty much the same size as an average-sized Labrador retriever. Male dogs can be between 22 and 24 inches tall, while females are smaller at around 21 to 23 inches tall, both weighing from 50 to 65 pounds.
Labradoodles that are produced by using Miniature or Toy Poodles are more petite.
A Miniature Poodle is between 9 and 15 inches in height and weighs from 15 to 17 pounds. Toy Poodles are under 10 inches tall, weighing only 4 to 6 pounds.
When you mix a Miniature Poodle with a Labrador, you get a Medium Labradoodle. Those dogs weigh from 30 to 45 pounds. Males are generally taller than females at 18 to 20 inches tall, whereas the girls are between 17 and 19 inches in height.
The Miniature Labradoodle is the smallest mix, coming in at 14 to 16 inches tall and weighing between 15 and 25 pounds.
A few years ago, various celebrities started a craze for owning “purse dogs.”
These tiny pups are small enough to literally fit inside a lady’s purse to be carried around as the ultimate companion fashion accessory. The rights and wrongs of that are a matter for debate, but the craze spawned a whole new variety of tiny Doodles and purebred dogs, commonly referred to as Teacups.
To produce a Teacup sized dog, much crossbreeding using tiny “runts” is necessary, often leading to puppies with congenital health problems and short lifespans. Reputable breeders do not generally attempt to produce a Teacup Labradoodle.
For that reason, we recommend that you steer clear of these pint-sized pooches that often come from unscrupulous puppy mills and backyard breeders.
What Size Are Labradoodle Puppies?
Labradoodle puppies vary in size, even between siblings in a litter. That variance is related to the size of the parent dogs and to what generation of breeding program the puppy comes from.
A Standard Labradoodle puppy typically weighs between 7 and 10 pounds by the time they get to two months old.
As you might expect, Miniature Labradoodles are quite a bit smaller, coming in at only 4 to 7 pounds by two months of age.
At two months old, a puppy typically weighs around one-quarter of its full adult weight. Generally, it then takes another 12 to 18 months or so for the pup to reach its full size and fill out.
While the puppy is growing, you must pay attention to its diet. It’s true to say that Labradoodles love their food, and it’s easy for a puppy to get fat if his doting pet parent overfeeds him!
Puppy Growth Calculators
So, is it possible to work out more accurately how big your puppy will be when he grows up?
There are various puppy growth calculators on the internet that you can use to get an idea of your puppy’s final size. To use the calculators, you need to know the size of each parent dog and the exact weight of your Labradoodle puppy.
Here are a couple of formulae that you can use to work out how big your Labradoodle puppy will grow to be:
- This is a commonly used formula that is quite accurate. Take your puppy’s weight at four months of age, double that figure, and add 10 pounds.
- This method is called the four-fold formula. When your Labradoodle puppy reaches two months of age, weigh him or her. The number you see on the scale usually represents one-quarter of the puppy’s estimated adult weight.
- Once your Labradoodle puppy reaches four months old, the number on the scale is usually around half of the pup’s estimated adult weight.
The wonderful, exciting months of puppyhood are over in a flash but your pup’s formative weeks and months are critical for your canine companion’s lifelong health. For that reason, you should only use these formulae as a guestimate and handy reference point. Be sure to take your puppy to see a qualified, experienced canine veterinarian for regular health checks and weigh-ins.

What Size Are Labrador Retrievers and Poodles?
So, you can see that there is a significant variation in Labradoodle heights and weights, which is not surprising given their genetic makeup.
Here’s a quick overview of Labrador and Poodle sizes to illustrate why Labradoodle sizes vary so widely.
- A male Standard Labrador retriever generally measures 22 to 22.5 inches tall at the shoulder, weighing between 65 to 80 pounds. Females are usually slightly smaller, measuring 21.5 to 22 inches tall from paw to shoulder and weighing 55 to 70 pounds.
- Standard Poodles are smaller than Labs. Both male and female Poodles can be 15 to 22 inches tall, weighing 60 to 70 pounds for male dogs and 40 to 50 pounds for females.
- Miniature and Toy Poodles can start at 4 pounds and just 10 pounds!
What Influences Adult Labradoodle Size?
There’s a whole range of influential factors that all have a bearing on your adult Labradoodle’s size, including environmental and genetic factors.
For example, a puppy might experience stunted growth because he has not been fed an adequate, correct diet, although that doesn’t play a big role in the dog’s final size. High-quality, correctly balanced nutrition helps the puppy meet its full potential.
So, what are the primary influences on a puppy’s final adult size?
There are several genetic influences that can determine the puppy’s adult size.
The size of the puppy’s parents have a massive bearing on the adult size of the dog, as explained above. That’s all very fine if you have an F1 Labradoodle since you know the exact size of the pup’s parents. However, in the case of multigenerational puppies, you can never be exactly sure of the size of the grandparents, great grandparents, et al. That makes the ultimate adult size of the pup unpredictable.
In general, male dogs of many breeds often grow to be significantly larger than females. However, that doesn’t necessarily apply to Labradoodles as there doesn’t appear to be any significant correlation between the dog’s adult size and gender.
However, Labradoodles that are spayed or neutered before they’re sexually mature can grow taller than average, so you should have a chat with your veterinarian regarding the best time to have your puppy desexed.
Diet and Nutrition
For your puppy to grow and thrive, he must receive a diet that contains the nutritional requirements that the pup needs both for muscle growth and to provide him with the energy levels he needs for play.
To help moderate your puppy’s growth rate so that it’s neither too fast nor too slow, you need to choose a puppy food formulated for your dog’s size.
For example, if you have a Medium or Miniature Labradoodle size dog, you’ll need to choose a food designed for the specific needs of smaller breed dogs. However, if you have a Labradoodle with a Standard Poodle parent, your puppy will be a larger dog, and you want food that supports that development.
Ask your vet or a specialist canine nutritionist for advice if you’re not sure what food to give your dog. Your vet will also help you assess your pup’s development and weight at every stage of the puppy’s rapid growth process. That will help you decide on the right size portion for your puppy.
