My sister has a Goldendoodle, my nephew has a Labernese, and a friend has a Bernedoodle. They all cost as much as a purebred. I have heard of a few others, but I had NO IDEA there were so many! I bet if you pick your two favorite breeds, you'll find them on the list.

Do you have a hybrid? Would you get one?
