That sad puppy "missing mom" reminds me of one of the shelties I take care of. I had the four of them for 3 days,
and by the third evening, the oldest sheltie (a cute, chubby butterscotch-colored boy) was so lonely for his mom
that he didn't even come over to beg for some of the burger I was eating. Despite having me and the other dogs,
he just wanted mom back and had the saddest little face.
