My roomate just bought a new dog a couple weeks ago! It is a Pyraneese/Lab mix. For only being 14 weeks old it can already sit and lay down on command.
He also knows to let us know to take him out and when we tell him "no" or "bad dog" he knows to stop!
Enjoy it while it lasts :P Once he gets a little more mature, he'll start testing his boundaries: not doing what you tell him to see what happens, how close you'll let him get to your face, or even take a really close look at what you're eating. I wish you good luck though!
