"I just want it to stop growing at one year"

This is called Paedomorphism (thanks Wikipedia) through Neoteny. Humans are a very good example of it.

Or cats (though I'm not sure about this one). See how Tiger/Lion cubs behave like regular cats? Moderate aggressiveness, meowing, etc?

I didn't click on this link, but I really hope the domestication experiment with foxes is not being called 'evolution'.

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.
