A Labradoodle, a crossbreed between a poodle and a retriever. A crossbreed or crossbred usually refers to an organism with purebred parents of two different breeds, varieties, or populations.
Normally, poodles are strongly line bred, for a combination of traits such as size and coat colour. Poodle crossbreeds or poodle hybrids are the offspring of purebred poodles that have been crossbred with another purebred dog breed. They may be described as a mixed breed dog, designer dog or, sometimes, as a hybrid dog. In biological terms, poodle crossbreeds are an intraspecies hybrid, rather than a hybrid between two different species, since all dogs belong to the same species and subspecies: Canis lupus familiaris.
