Labradoodles are a popular mixed breed that can grow to a wide variety of sizes depending on the parent breeds. From miniature to standard labradoodle and sizes in between, these designer hybrid mixes are bred to be hypoallergenic service dogs and make wonderful companions to any family. This post should help familiarize potential owners with which size labradoodle could be right for them, how their stages of growth work and what the likely relationship is between their juvenile and adult weight.

Types of Labradoodle

Labradoodles come from a mixture of poodle and Labrador retriever stock, chosen to provide the charisma and sociability of a Labrador with the fluffy, low-shedding coat of a poodle. They’re classified depending on the specifics of their breeding and particularly on whether they have purebred parent breeds.

A 50-50 mix of Labrador and poodle is called an F1 labradoodle. An F1 labradoodle breeding pair involves purebred parents. The mother is almost always Labrador and the father poodle to ensure that the mother can safely birth the resulting puppies.

Other classifications feature progressively less purebred parentage. An F1B labradoodle, or doodle mix, comes from an F1 doodle parent and a purebred parent, either a Labrador or a poodle. F2 labradoodles have two labradoodle parents, and F3 or multi-generational labradoodles have their closest purebred parent in their grandparents’ generation or older.

The specific characteristics of their parentage will determine the mature size of a labradoodle. In general terms, there are three size ranges: miniature or toy doodles — produced in an F1 generation by mating a toy poodle with a Labrador retriever — medium and standard.

How Big Do Labradoodle Puppies Get?

The size of labradoodle puppies directly relates to the size of their parents and which generation of breed they come from. The larger the puppies, the larger the adult dog will be and the faster their growth will be coming out of the puppy stage.

A standard labradoodle puppy will weigh from 7-12 pounds by the time it reaches two months of age. By a year old, it will have grown dramatically to up to 80 pounds, depending on the size of its parents.

Miniature labradoodle puppies fall on the smaller and slower-growing end of the spectrum, weighing only around 4-7 pounds by the two-month mark and around 30-45 pounds by the time they’re a year old, again depending on the size of each parent.

Medium labradoodles occupy a spectrum of sizes between those two poles, with the specifics depending heavily on the details of the breeding pair that birthed them and the breeding program they come from. You’ll want to learn as many of these details as you can to be able to provide for your puppy’s health as it grows.

Labradoodle Growth

How fast your labradoodle puppy grows, and its health needs as it grows, will depend on its starting size and breed characteristics. There are a number of ways to estimate what its overall growth rate will be, but at the end of the day, remember that estimates, calculators and rules of thumb are no replacement for regular weigh-ins and check-ins at the vet. Puppyhood is a comparatively brief time in a dog’s life, but it’s crucial to its lifelong health.

There are a couple of commonly used formulas to estimate what a labradoodle dog will weigh as an adult. The “fourfold formula” assumes that the dog will have reached one-quarter of its adult weight by two months of age. The “double-up formula” assumes it’s at half its adult weight by the four-month mark. These, however, are really just rough rules of thumb that can’t account for the differing rates of growth between different types of labradoodle. So remember to take them with a grain of salt.

A labradoodle puppy’s food needs to be adjusted to support its body’s needs throughout the rapid growth of the puppy stage. Miniature doodle pups will need food formulated for small-breed dogs, whereas standard pups will need food made with medium- or large-breed dogs in mind. Medium doodles might fall on either side of that divide.

Your vet can advise you about your puppy’s growth and what kinds of food it will need every step of the way so you can help it reach its mature size and weight as its healthiest possible self.

Adult Labradoodle Size

Adult labradoodles occupy either miniature, medium or standard sizes ranges for height (paw to shoulder) and weight. Miniature labradoodles range from 14-16 inches in height and weigh from 15-25 pounds. Medium labradoodles range from 17-20 inches in height and weigh from 50-65 pounds. Standard labradoodles stand from 21-24 inches tall and weigh from 55-95 pounds.

There is clearly a lot of variance within each of these size ranges, and it can sometimes be complicated to predict the adult size of a labradoodle. That’s particularly true if it comes from an F1 breeding program, which can involve considerable size difference between the poodle parent and the Labrador retriever mother.

A dog’s adult size will also be influenced by its sex, since male dogs will tend to be 5-10 pounds heavier than their female counterparts. But this, too, can vary widely depending on the parental breeding pair and the dog’s diet during the puppy stage.

In general, if you want to be able to predict your labradoodle’s adult size with the most accuracy, it’s best to work with an F3 or multigenerational breeder. Get as much information as you can about the parent dogs before committing to a puppy if you have your heart set on a specific size of adult labradoodle.
