Does a toy poodle stay little forever?

Toy poodles do not stay little forever, but they do mature slowly and have a longer lifespan than some other small dog breeds. They typically reach full size by around 12-18 months of age, but may continue to fill out and gain weight for a few more months after that. Toy poodles generally weigh between 4-6 pounds and stand about 10 inches tall at the shoulder. They are considered to be fully mature at around 2-3 years of age.
