They are not prone to snapping, so they are good with young children. They may or may not bark when strangers arrive, and are not suited to be guard dogs due to their trusting and unsuspicious nature. Unlike many other breeds, the males are as easy to housebreak, and no more aggressive than bitches. Both sexes make excellent pets. Males tend to be slightly more loyal and enjoy repetitive play.
Females can be a little more complex and strong-willed, but are equally devoted to their owners.
Males tend to run one to two inches taller, and three to six pounds heavier, than females. Whippets, like other dogs, require a good quality kibble and plenty of fresh water. They are not well-adapted for living in a kennel or as outside dogs. Their coats do not provide the insulation for them to withstand prolonged periods of exposure to the cold. Their natural attachment to people makes them happiest when kept as housepets.
