perro

dog (the species Canis familiaris (sometimes designated Canis lupus familiaris), domesticated for thousands of years and of highly variable appearance because of human breeding); clothes peg, clothespin; asshole (despicable person); lazy person

“perro callejero” — stray dog

Inherited from Old Spanish perro (“cur”) (ca. 1200), of uncertain origin. Originally had a pejorative connotation, but soon began to supplant the Latin word can. Perhaps from a call used for dogs; compare Galician apurrar (“set the dogs on”). Another theory derives it from Iberian; compare Asturian perru. If so, it may be related to Spanish zorro.

doggy or doggish; awful; wicked; mean
