Description of a Galgo Espanol.

The Galgo Español (Spanish Galgo) or Spanish Greyhound is an ancient breed of dog, specifically a member of the sighthound family. The Galgo was named for the Gauls, who inhabited the Iberian Peninsula 400–600 B.C.E. The Galgo breed was probably a result of the dogs brought by the Gauls on their migration through the peninsula mixed with dogs brought by traders who did business with the Gauls.

In the intervening centuries, it is likely that other sighthound breeds were interbred to produce the Galgo that we know today.

Despite being called a "Spanish Greyhound", the Galgo is not truly a Greyhound. The lineages of the two breeds are different. However, in the last century or so, some breeders have cross-bred Galgos and Greyhounds in order to produce faster Galgos.
