Because Greyhounds are an ancient breed of hunting and coursing dog with all the inherent instincts, small running animals may be confused with prey. Many who live with both Greyhounds and small dogs let them out at different times of day, or maintain two separate play areas. Contrary to misconception, Greyhounds do not need a large area to run every day. Greyhounds must never be off-lead in an open area. Because of their ability to reach speeds of 35-40 mph at full stretch, a startled Greyhound can end up miles away and hopelessly lost.
Many Greyhounds collect and hoard everything from slippers to keys to the remote control.
The good news is that they are not destructive. This low-key nature makes them suited even for townhouses and apartments if they are exercised regularly. Having little to no body fat, Greyhounds must always be provided with a soft place to rest or sleep because their bones are unprotected on hard, cold surfaces. And because their skin is easily torn, they should be kept away from thorny bushes and wire fences. The rarest color is grey.
