One of the most famous adventure heroes of the 20th century United States, The Shadow has been featured on the radio, in a long-running pulp magazine series, in comic books, comic strips, television, serials, video games, and at least five films. The radio drama included episodes voiced by Orson Welles.
Spotting anxiety comes more easily. Owners are less likely to push a dog past what it can tolerate. However, contrary to popular belief, a wagging tail does not always mean a happy dog. It is just not possible to take one isolated behaviour and draw a conclusion.

Similarly to cats, a dog's tail can express a lot of different emotions, from anxiety to relaxation. Doggie tails are rather sophisticated communicators.

When a dog is feeling calm, cool, relaxed and content, he may keep his tail down next to his hind legs and lower thigh area.
