Historically Greyhounds have had a reputation for being gentle, people-centered dogs, and "par-excellence for persons wishing for a companion for themselves or their children". When Greyhound adoption first started in the United States, many people associated with racing argued that Greyhounds did not make suitable pets. However, as the number of greyhounds successfully transitioning from tracks to households has risen, many people have come to believe that greyhounds are good companions. They describe Greyhounds as gentle and affectionate dogs who adapt easily to household life because they have clean, short coats and require only moderate exercise.
