The Miniature Goldendoodle is a crossbreed, not a purebred dog. It results from the mix of Golden Retriever and Toy, Miniature, or small Standard Poodle. Some Miniature Goldendoodles are first-generation crosses between a Golden Retriever and a Miniature Poodle, while others may include Toy Goldendoodle. Breeding these smaller sizes can involve surgical or artificial insemination, leading to varying sizes. Temperament varies and combines traits from both breeds. Breeding methods differ among breeders, including multi-generation crosses, so inquire about their specific approach. These designer hybrid dogs offer diverse characteristics and are not always 50% purebred to 50% purebred.
