The other day I was watching television and my oldest was going nuts. He kept going to the footstool, grunting, and coming back to me. Back and forth...back and forth. This went on for about five minutes. He usually does this if one of his toys is missing, but the stool is so low that there couldn't possibly be a toy underneath.
I figured he was just having an episode and tried to ignore it, but he got louder and more insistent. It was obvious I could not watch television in peace until I discovered what was going on.
So I went over to the footstool, moved it and sure enough - there was one tiny kibble of dog food under the stool. Bruiser promptly grabbed it, ate it in a split second, and went along his merry way. I might mention that the boys had a pile of dog food sitting in their dish. But Bruiser absolutely had to have that one piece that was under the stool.
And that's the Shih-Tzu. When something is theirs, they want it and they want it when they want it, and you will have no peace until they get it.
