If you are a dog you know what the so-called owners want you to do and what they don't want you to do. We may not always obey but hey, we know this stuff like the back of our paw! In our house there is a special device that apparently indicates that it is very important that our owners are left alone. When we are shown the stylized apple (above) we know it is time to go and lie down and be quiet for a long time. Our owners seem to go into a trance when they put up this "shield" between themselves and us. I am guessing that the apple symbolizes something very profound and deep, perhaps a symbol rooted in human mythology somehow... Again, humans are very strange creatures.
