英國一隻格雷伊獵犬於過去六年捐血了22次，幫助了約88隻狗隻，但近來因達九歲，屬超齡捐血而不能再繼續。陰性血液可提供給任可狗隻使用，約有30%的狗隻有陰性血液，而這隻格雷伊獵犬是其中之一。
In UK, a greyhound donated its blood 22 times in the past six years and helped around 88 dogs. But it has recently reached the age of 9 and has to retire as donation is only taken from dog aged from one to eight. Negative blood can be given to any dog but only around 30% of the dogs has this blood type; and this greyhound is one of them.
