Why not, I dunno, tell her that the dog NEEDS the full pill? And also to not overfeed her since it makes her go (and dogs typically will eat constantly if you let them)?
But yes, I see this. There's also not much of an answer, sometimes, because we've had times where our 18mo was exhibiting weird things or annoying things and it's just... annoying and weird. But nothing wrong. Not all answers are found in books, sadly, but not all of them should be or you won't actually understand the problem and resolution, merely use it and hope for the best next time.
