Labradoodles come in 3 sizes: Miniature, Medium, and Standard. Miniature Labradoodles usually weigh between 15 and 30 pounds. Medium Labradoodles typically weigh 30-45 pounds. Standard Labradoodles weigh more than 45 pounds and may weigh as much as 100 pounds. Since Labradoodles are hybrids, there are no guarantees about how big they will get. The best thing you can do is see the size of both of the parent dogs to estimate how large your puppy Labradoodle will grow to be.
