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 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.
