Gizmo has started barking more-- the first five, six days we had her she barely made a sound, but now that we've had to leave her on her own more (not more than four 1/2 hours at a time) she's been a little fussier. She whines if left alone too long, but I think the barking usually indicates she really has to "go." I pointed that out to my fiance and since then we've been trying to not to discipline her or show displeasure at her trying to tell us she's gotta go to the little corgis' field.
She's only just over ten weeks so we keep her close to us when we're home, and crated when we're not, so she can't get into anything, so we haven't had a chance to notice any neediness or lack thereof.
