Old SymbolsWhere every symbol began

Plate 1 Two letter W shapes drawn together in one zigzag line

Dog here

Two letter W’s run together, reported to mean that a dog lived at the house; other marks warned of a dangerous dog.

Hobo symbols. Also called bad dog hobo symbol, barking dog hobo sign, hobo dog sign.

Meaning

Dan Beard wrote in 1918 that two letter W’s joined together were sometimes used by tramps for a dog, perhaps for the way a dog jumps up and down when it barks at a stranger, and that a rectangle with a fence inside it meant a dangerous dog in the yard or house. The National Cryptologic Museum’s sample sheet draws the joined W’s for “Barking dog lives here”, and a stretch of fence with the figure 2 for “Beware of two dogs”.

Origin and history

A Boston article printed in 1908 gave yet another form: a box with two N’s run together inside it, “the high sign that there is a dog in the garden”. The three versions agree on the subject and differ in the drawing, which is the pattern of the hobo signs as a whole.
