When do Irish Doodles stop growing?

Irish Doodles stop growing by around 12 to 18 months. Smaller Irish Doodles (from Miniature Poodle parentage) may reach their full size closer to 12 months, while larger ones (from Standard Poodle parentage) may continue to fill out and gain muscle until about 18 months. Their height is usually set earlier, but their weight and body structure may continue to mature.
