What does f1 Cavapoo mean for dogs and what do breeders mean by f1b and f2?

These are symbols depicting the different generations and parents used to produce these puppies.


F1 is a symbol given to the first generation offspring that result from mating a Cavalier King Charles Spaniel to either a Toy or Miniature Poodle. Both parents are purebreds. The resulting puppies are called hybrids or cross breeds.


F2 is allocated to a puppy when two F1 adult dogs are mated together. So both parents are Cavapoos.


A F1b puppy is the result of one of the parents being an F1 adult dog (Cavapoo) and the other parent being either a Cavalier King Charles Spaniel or a Poodle. Most of the time the second parent is a poodle.

Hopefully, the diagram below will help you to see the differences.
