更让人难以置信的是它还可以区分出节拍器每分钟震动数为96或100次，133次与144次。狗对于人的口令和简单的语言，可以根据音调音节变化建立条件反射。
特别要注意的是我们没有必要对狗大声叫喊，过高的声音或音频对它来说是一种逆境刺激，会使它有痛苦，惊恐的感觉，当然在它犯错误时，可以提高声音来管教它。狗的听觉十分敏锐，听觉感应能力可达12万赫兹，是人类的6倍，它能听到的最远距离大约是人的400倍！狗对于声音方向的辨别能力也是人类的2倍，能分辨32个方向。其寿命约十多年，狗的寿命大约在12-18年之间，最长的也有20年以上,不过很少见。与猫的平均寿命相近。平均寿命以小型犬为长

Dogs(狗)
Dogs belong to the canine.
When a dog follows its nose, it’s 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 it’s 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 dog’s 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.

狗属于犬科劝物。
当狗用鼻子嗅着前行时，实际上有三种感觉在起作用：视觉，瞥一眼就知道敌人在哪儿；听觉，犬吠有一种凶猛的威慑力，这也是犬科动物闽相互嗅寻的方式；嗅觉，能给狗提供的信息比其他感觉总和还多。
狗的鼻孔大约有2亿左右的嗅觉细胞——比人多40倍。通过这些细胞，它的大脑能从100万个气体分子中筛选出1个。根据所闻而不是所见的东西，展现给狗的是一个完全不同的画面。
花对狗来讲无足轻重，所以花香对狗无关紧要。可食物是件大事，对我们来说是一个空盘子，可对一只饥肠辘辘的狗来说却散发着鸡肉的香味
