关于狗狗的3件事

3 Amazing Facts About Dogs!

[介绍]
[Intro]
这是路易 一只猎犬
This is Louie. He’s a hound.
这是Auzzy 一只澳大利亚牧牛犬
This is Auzzy. He’s an Australian cattle dog.
这是艾比 一只柯基犬
And this is Abby. She’s a corgi.
他们虽然长得不同 但他们却是人类最早驯养的宠物品种
They look pretty different, but they’re all examples of humans’ very first pets
狗狗!
— dogs!
即使你是养狗狗的 但我敢保证你是不清楚这些关于我们披着皮毛的好朋友
Even if you have a dog of your own, I bet you don’t know some of these amazing things
的一些令人惊奇的事情的
about our furry best friends.
例如,你知道所有的狗狗都与狼有关系吗?
For example! Did you know that all dogs are related to wolves?
没错!他们与狼有关系
That’s right! This is related to this.
记得我刚刚说的 狗狗是人类最早驯养的宠物吗
Remember how I said dogs were human’s first pets?
大约在15,000年前 人类和狼共同存在于这个地球上
Well, about 15,000 years ago, humans lived alongside wolves. And in time, some of these
一段时间后 一部分狼被人类驯养
wolves became domesticated, meaning that they changed from being wild, to being able to
这意味着狼从一种凶猛的动物变成和人类共同合作的好伙伴
live and even work closely with humans.
经过几千年的演化 一些狼变成了
So, over thousands of years, some of those wolves became the domesticated dogs we know
我们所熟知的家养狗
and love!
野生狼仍生活于世界上的某些地方
Wild wolves still live in many places in the world today. But there are also more than
但世上也同时存在着400多种不同品种的狗
400 different breeds of dogs!
地球上所有的狼和狗都被认为有着同一个祖先:
And all of the wolves and dogs on Earth are thought to have descended from the same animal:
一个数万年前徘徊在地球上的捕食者
a predator that roamed our planet millions of years ago.
科学家称它为”Eucyon davisi”它长得有些像现在的狗狗
Scientists called it Eucyon davisi, and it looked a lot like today’s wolves, with one
但两者最大的不同就是 它可能体积比较大
major difference: It was probably a lot bigger.
那么 假设所有的狼和狗都有着共同的祖先
So if all wolves and dogs descended from this early predator, that means wolves and dogs
我们就可以认为狼和狗是有一定关系的
are related!
狗狗和一些和它长得相似的动物也有关系––比如狐狸啊 豺狼啊
Dogs are also related to other animals that look a lot like them — including foxes, jackals,
还有土狼啊
and coyotes.
狼和这些肉食哺乳动物一起被称为犬齿科
Together with wolves, these meat-eating mammals are called canines.
这是个超大的有毛动物家族
That’s one big furry family!
另一件狗狗的炫酷之事就是它们超级灵敏的嗅觉
Now, another cool thing about dogs? They’re super-smellers!
它们鼻子里的嗅觉细胞比人类的多出40倍
Their sensitive noses have 40 times more cells in them for smelling than ours do — plus
除此以外 狗狗可以用人类做不到的方式扭动它们的鼻子
they have the ability to wiggle their noses in ways that we can’t!
这可不是一个一本正经的小把戏––通过分别扭动鼻孔的方式
And that’s not just a neat trick—by wiggling each nostril separately, dogs can figure out
狗狗可以辨别味道是从哪里散发出来的
which direction a smell is coming from.
当它们出生时 小狗狗是看不到也听不到任何东西的
So, when they’re born, puppies can’t hear or see anything, but they quickly learn to
但是很快 它们可以学会如何用嗅觉找到它们的母亲
find their mom—and other important things in the world around them—just by using their
这是它们生活中的另一件大事
sense of smell.
狗狗遇到他们的新朋友时也用它们的嗅觉
Dogs also use their smelling skills when they meet new dog friends.
狗狗互相闻对方的屁股而不是握握对方的爪子或吠着说你好
Instead of shaking paws or barking to say hello, dogs sniff each other’s butts!
狗狗既不是用名字也不是凭长相认出对方的
Dogs don’t recognize each other by name, or even by looks; they identify other dogs
它们是靠味道确认对方身份的
by how they smell.
因为所有狗狗的屁股后面都有一种特殊的嗅觉腺体
That’s where they sniff, because all dogs have special scent glands on their rears,
狗狗用这种气味来认识对方
and dogs use those scents to learn about each other!
通过闻味道 狗狗可以辨别小狗狗是年幼的还是年长的 是男孩还是女孩
By sniffing, a dog can tell if another pup is young or old, a boy or a girl, if he’s
它是生病了还是健康的 甚至能知道它现在心情怎么样
sick or healthy, and even what kind of mood he’s in!
但并不是所有的狗狗都会去闻屁股的
Not all dog sniffing involves butts, though.
有很多狗狗的强大的嗅觉能力被运用到了别的地方
Lots of dogs put their powerful sense of smell to use in other ways: Some dogs can sniff
一些狗狗被用来当搜救犬 一些被用来当猎犬 还有一小部分
out and rescue people who are lost, some hunt for escaped criminals, and a few are even
被训练用来发现致命的疾病
being trained to sniff out deadly diseases.
好神奇啊 营救神犬耶
That’s awesome! Super dogs to the rescue!
最后 第三件炫酷的事就是:它们可以
And lastly, our third cool thing about dogs: Some of them can remember more words than
比小孩子记住更多的词
a baby person.
即便它们不会说话 狗狗仍旧是个超棒的聆听者
Even though they can’t talk, dogs make great listeners.
大多数的狗狗可以理解大约165个单词––而不单单是”坐下”或者”待着别动”
Most of them can understand about 165 words—way more than just “sit,” or “stay.”
有些狗狗甚至可以记得更多
And some can remember even more than that.
一只博德牧羊犬在经过训练后可以理解超过一千个单词
One border collie was trained to understand over a thousand spoken words–and she learned
它可以像小孩子一样快速学会这些词
those words as quickly as a small child would.
所以 狗狗很聪明哦
So, dogs are smart!
不论你何时看到了一只杂交狗––管它是不是长得像Abby, Auzzy, Louie或者
Now, whenever you see a pooch — whether it looks like Abby, Auzzy, Louie, or someone
别的狗狗––你要知道你看到的是一只非常聪明且
completely different — you’ll know that you’re looking at a really smart relative
嗅觉灵敏的野生狼亲戚
of wild wolves with a super sense of smell!
