　　Dogs belong to the canine.

　　When a dog follows its nose, its actually being led by thee key senses. Sight:a glimpse of the enemy saves them barking up the wrong tree. Sound: a bark can be a fierce threat, but its also how canines make their long distance calls. Smell: this tells a dog more than all the other senses put together.

　　Inside its nose are around two hundred million smell sensitive cells, forty times more than in humans. Through them the dogs brain can pick up signals from one molecule of scent in a million. It gives the dog: a completely different picture of the world, based on what it smells, rather than what it sees.

　　Flowers are irrelevant to a dog. So their scent is meaningless. But food is a serious matter. What to us is an empty plate, is covered with the smell of chicken to a hungry dog.

　　狗屬于犬科勸物。

　　當(dāng)狗用鼻子嗅著前行時(shí)，實(shí)際上有三種感覺(jué)在起作用：視覺(jué)，瞥一眼就知道敵人在哪兒;聽(tīng)覺(jué)，犬吠有一種兇猛的威懾力，這也是犬科動(dòng)物閩相互嗅尋的方式;嗅覺(jué)，能給狗提供的信息比其他感覺(jué)總和還多。

　　狗的鼻孔大約有2億左右的嗅覺(jué)細(xì)胞比人多40倍。通過(guò)這些細(xì)胞，它的大腦能從100萬(wàn)個(gè)氣體分子中篩選出1個(gè)。根據(jù)所聞而不是所見(jiàn)的`東西，展現(xiàn)給狗的是一個(gè)完全不同的畫面。
