Trying to impose what you want the pack order to be often results in more headaches. Let the dogs figure it out themselves. If Jasper winds up being the more submissive of the two, than that's OK. If you try to do things to undermine that, you can wind up with some serious issues on your hands.

Let the dogs figure it out and only intervene if you're concerened someone will get physically hurt. Actually, things may rev up a bit when the poodle reaches sexual maturity and/or when the poodle reaches 18 months to over 2 years old.
