n. (alternative form of lap dog English)
Wikipedia
Lap-dog (1823–1838) was a British Thoroughbred racehorse and sire. His racing career consisted of a single season, 1826, during which he ran eight times. After finishing unplaced on his racecourse debut, Lap-dog won his next four races including the Epsom Derby. He was retired to stud at the end of the year, but had little success as a sire of winners in England and was later exported to the United States. His name appeared in variations including Lapdog, Lap Dog and The Lap Dog.
