His ability to reach top speed quickly is amazing. At maximum acceleration a greyhound can reach a speed of 45 mph (72km/h) within its first 6 strides from a standing start. No other land animal (except the cheetah) has that degree of acceleration.

However, the greyhound is also a distance runner. He can settle into a speed in excess of 35 miles per hour and can run at that rate for distances as great as 7 miles (11 kilometres). This means that while the cheetah can win the short sprint race, in any long race the greyhound will leave that big cat way behind, panting in the dust.

The really fast dogs are greyhounds, whippets, salukis, <IMG height="144" width="241" alt="greyhound" src="http://www.psychologytoday.com/files/u162/running%20dog.gif" />and Afghan hounds which are called sighthounds since their job is to spot their quarry by sight, and run it down. The characteristic shape of these dogs involves a huge chest to accommodate large lungs to gulp oxygen and their over sized heart, plus a narrow waist that allows them to bend their body so that every stride carries them more than a body length.</P></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.psychologytoday.com/blog/canine-corner/200908/could-dogs-be-the-fastest-land-animals-in-the-world">The fastest of these dogs is the greyhound. He is specially designed for sustained high speed running. While he is going at full tilt the dog's heart rate can rise to 300-360 beats/minute-this means that the greyhound heart can contract and refill with blood five times per second during a race allowing oxygen to be transported at a phenomenal rate to supply the needs of the muscles.</blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;">&nbsp;</td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/A239FAB8-835E-4C0F-8D71-99BCC4617989/blog/" title="blog or email this clip"><img src="http://content8.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
