The first generation (F1) standard size Goldendoodle was the first to be bred. It is the product of a standard Poodle crossed with a Golden Retriever. Most first generation Goldendoodles either don't shed or shed lightly, and are compatible for most families with mild allergies. The backcross (F1b) Goldendoodle is produced by crossing an F1 Goldendoodle with a Poodle.
