beware of dog. A warning that property has fierce protection.
Some people choose not to invest in home security, but simply in signs warning that the home has security, whether of the canine or the alarmed sort. |

Even if you have a dog, not all household pets are reliable watchdogs. It may be equally important for property owners to beware of trusting too much in their dog's ability to provide protection, unless the canine has been specifically trained. There is, of course, the dog made famous by Conan Doyle whose silence Sherlock Holmes found worthy of comment. That dog failed to protect a horse in the stable because the dog trusted the thief. And then there is the mythical guardian of Hades, a three-headed dog with a snake for a tail, Cerberus, who turned out to be readily tamed by Orpheus's lyre.
The phrase is most often lettered on a sign for strangers to read on approaching a home or business. There are, no doubt, numerous establishments so labeled even though no dog resides there; the sign is posted simply to discourage entry. In this case, it may be less a matter of issuing a warning as one of trying to sell woof tickets.
The Romans apparently felt that this warning was good advice. Rather than post a sign, some of them included this warning in their mosaic floors: cave canem. The location of the words does leave it unclear: who was being warned about what? |

| About the illustrations: I found Figure 1 quite unnerving when I first came across it. Indeed, it probably reflects the true nature of the threat, even when enforced by dogs: it is the human owners who determine what is protected. Dogs are not all that interested one way or the other, except as it may matter to the pack as a whole and to the extent that the dog has been trained. Unlike their canine forebears, dogs are only mildly territorial, marking boundaries more as conversation than to claim anything.
