Definitely an angry dog in the sweater.
Years ago, my sister bought red boots for our dog, Charlie Brown, for Christmas. Our mother told her she was nuts if she thought the boots would be put on the dog everytime he went out in wet weather. We ended up only putting the boots on when we wanted to make him walk funny - he would lift his legs really high to try to rub the boots off against his body. Definitely a mean streak in all of us when we were kids. (It was along the lines of putting tape on a cat's paws - or so I have heard.) :D
