The size of Goldendoodle is influenced by its genetic mix. If a smaller Poodle is bred with a Golden Retriever, the Goldendoodle may be mini or medium-sized. Mini Goldendoodles are ideal for apartments, while medium and standard sizes fit better in larger spaces. Weight ranges from 15 to 100 pounds depending on the size type. Understanding the size of Goldendoodle helps you prepare for their needs, such as space, food, and exercise. This makes them a perfect fit for your family and home environment.
