They are very loving, and enjoy the company of their humans and other dogs. Whether a Greyhound will enjoy the company of other small animals, such as cats, depends on the individual dog's personality. Systematic archaeozoology of the British Isles, 1974  ruled out the existence of a true greyhound-type in Britain prior to the Roman occupation, confirmed in 2000. Written evidence of the historic time, the Vindolanda tablets (No 594), from the early period of Roman occupation demonstrates that the occupying troops from Continental Europe either had with them in the North of England, or certainly knew of the vertragus and its hunting use.All modern pedigree Greyhounds derive from the Greyhound stock recorded and registered first in private studbooks in the 18th century, then in public studbooks in the 19th century, which ultimately were registered with coursing, racing, and kennel club authorities of the United Kingdom. Historically, these sighthounds were used primarily for hunting in the open where their pursuit speed and keen eyesight were essential. .
