By most accounts, the history of the industry begins with a man named James Spratt. An electrician from Cincinnati, Spratt had patented a new type of lightning conductor in 1850. Later in the decade, he traveled to England to sell it.

The first major chunk of today's pet industry was born.
In Spain, "pan de perro" is mentioned as early as 1623 in a play by Lope de Vega. It is used here in the sense of giving someone blows; to "give dog's bread" to someone could mean anything from mistreating them to killing them. The latter meaning refers to a special bread (also called zarazas) made with ground glass, poison and needles and intended to kill dogs.
