You can often see our whoodles being described as one of the following F1, F2, or F3, or even F1b or F2b. These are terms that breeders use to distinguish different generations of a mixed/hybrid dog breed.
P Generation
100% Purebred Dog
A P generation dog is a purebred dog. In our case, this would refer to a pure bred soft coated wheaton terrier, or a pure bred poodle.
Example: a soft coated wheaton terrier or a poodle


F1 Generation
50% Purebred-A, 50% Purebred-B
An F1 puppy is the result of breeding two purebred dogs of different breeds.
Example: a whoodle whose parents are a purebred soft coated wheaten terrier, and a purebred poodle

F1b Generation
75% Purebred-A, 25% Purebred-B
The b in F1b stands for backcrossed. This means you would breed an F1 dog with a P dog. Normally this is done when there are more traits from one of the breeds that the breeder hopes to appear in the puppies.
Examples: a whoodle whose parents are an F1 whoodle, and a poodle, or a whoodle whose parents are an F1 whoodle and a wheaten terrier

F2 Generation
50% Purebred-A, 50% Purebred-B
F2 puppies are created when you breed to F1 parents.
Example: a whoodle whose parents are two f1 whoodles

F2b Generation
75% Purebred-A, 25% Purebred-B
Remember: that F2 means the puppy is 2nd generation, and the b stands for backcrossed!
F2b means that the puppy is a second-generation backcrossed puppy. F2b dogs are the result of an F1 parent being bred with an F1b parent.
Example: a whoodle with an f1 whoodle parent and an f1b whoodle parent

F3 Generation
50% Purebred-A, 50% Purebred-B
An F3 puppy in an offset from the mating of two F2 hybrid parents.
Example: a whoodle where both parents are F2 whoodles
