Why not? Reproduction with variation and selection (by the humans). Seems like evolution to me.

Because evolution relies on survival of the fittest and genetic mutation. Your Chi-Pom-Poodle-Terrier isn't an evolutionary step for the canine. And most of all I don't want creationists to think that 'hand of god' is a valid evolutionary driver ;)

> Because evolution relies on survival of the fittest

Which is defined by the humans in this case.

> Your Chi-Pom-Poodle-Terrier isn't an evolutionary step for the canine.

Any change is an 'evolutionary step'. You're thinking in dangerously telelogical and moralizing terms.
