I'm not sure what it is about opening presents but our yellow lab cross was so excited when we started opening our stockings, we had to give her one of hers. She was like a kid on christmas, opening the present and then wanting the next one. She settled down a bit when she was able to stick her head in the treat bag and pull out a few goodies. She really liked the stuffed pig she got (although to me it looks like a hybrid between a pig and a sheep) and in no time, the ears and tail were missing. Now, she just likes to carry it around the house.
