LOL, yes, some dogs choose the oddest things to bark at. Bringing back a memory of Blue, a dog I had many years ago along with three others, Duke, Max and Duchess, anyway, Blue was such a wierd fellow in many ways and one of them was how he would bark at the big sacks of the complete dog food at delivery time, I would be pulling them down the hall with him behind me barking away telling those sacks to behave or else! Then once they were stored away he lost interest, except at feeding time of course!
