The Goldendoodle is a cross between a Golden Retriever and a Poodle (usually a Standard or Miniature). At their best, they are intelligent, friendly, and affectionate. They come in three sizes: miniature (weighing 15 to 30 pounds), medium (30 to 45 pounds), and standard (45 to more than 100 pounds). Because they are a cross breed, their traits are not fixed, so there is not a guarantee that the Goldendoodle puppy you purchase will fall into the desired weight range.
