Karbit has a very good reputation for producing excellent poodles. I am sure that if you contact them, they can tell you the specific pairings that are expecting litters for the next year or so. Usually with very good breeders like Karbit, there is a bit of a waiting list so you will hear about what their plans are and then you and the breeder can discuss whether you want to get on the waitlist.
Do keep in mind that Covid has caused a puppy shortage and most breeders are overrun with people asking if they have pups available. Keep this in mind when contacting. Be patient, and give a good description of yourself and why you are interested in one of their pups. Calling can also be helpful if you don't get an email response.
