     Most people think of racing when they see greyhounds(灰狗)
and believe they need lots of exercise. They can actually be quite
lazy! Greyhounds are good at fast races but not long-distance run-
ning. They do need regular exercise but they like to run for a short
burst and then get back on the bed or a comfortable seat. Another
misunderstanding is that greyhounds must be aggressive (好斗的)
because they are big in size. In fact greyhounds love people and are
gentle with children.
     Greyhounds can live for 12～14 years but usually only race for
two or three years, and after that they make great pets. They don't
need a lot of space,don't make a lot of noise,and don't eat a lot for
their size.
      Normally, greyhounds can be as tall as 90cm. There is, however,
a small-sized greyhound, which stands only 33cm. Greyhounds
come in a variety of colors. Grey and yellowish-brown are the most
common. Others include black, white, blue, red and brown or a mix
of these.
      Greyhounds have smooth body coats ,low body fat and are very
healthy. Because they're slim (苗条的)they don't have the leg
problems like other dogs with the same height. But they do feel the
cold ,especially since they would much rather be at home in bed
than walking around outside.
