Because my dog has an injury on her foot, she has to wear a cone. She doesn't quite get the concept that there is an invisible forece field around her head. So she gets stuck walking around corners and going up stairs. When she tries to walk up to me her head stops a couple inches be fore my face, it's so funny. I told her when I first saw her with the cone on, "You are an embarassment to be seen with, even in the privacy of my own living room."
