The Goldendoodle is a cross between a Golden Retriever and a Poodle purebreds. They are called hybrids due to their origination from two different pure breeds.
The Goldendoodle are found in three sizes depending up on what size of Poodle was involved in cross breeding. The three sizes for these hybrids are standard, medium and miniature. As an adult, a standard Poodle weighs 45 pounds or more; a medium weighs 30-45 pounds and a miniature weighs 15-30 pounds.
