We have all heard it said that the dog is man's best friend.
Well, that runs true to form, for we all know how most people treat their friends. The dog is no exception. For the dubious honor of being humanity's best friend, the canine is constantly being dogged.
If you think about all the similes in our language that refer to dogs, you would think people hate them.
For example, did you ever see a drunk dog? Not only that, but people say, "lie like a dog, sick as a dog, treated like a dog, working like a dog," and the list goes on and on.
