There are two main types of "Doodles":
1) Labradoodles = LABRADor retriever + pOODLE
2) Goldendoodles = GOLDEN retriever + pOODLE
The Labradoodle originated in Australia close to twenty years ago and was bred intentionally
to combine the reduced allergens and non-shedding traits of the poodle with the temperment of the Labrador. Since the popularity of the Labradoodle has taken off, other "doodles" have become popular as well such as the
Goldendoodle.
There are different classifications for the different generations of doodles:
F1: First Generation, a Lab bred to a Poodle (50% poodle, 50%
lab). Because this is a first generation cross the coat, build and size has a much greater potential for variation.
F1b: an F1 "back-crossed" to a poodle (75% poodle, 25% lab) usually
for a curlier coat and lower shedding possiblities.
Multi-Generation: F1's and F1b's from different genetic backgrounds
crossed together over several generations. The multi-gens have the most predictable coats and sizes.
