鏟屎官大科普:狗狗的11種超能力

1.超級敏銳的嗅覺

Dogs’ sense of smell is 10,000 to 100,000 times more sensitive than that of humans.

狗的嗅覺比人要靈敏10,000到 100,000倍。

2. Internal storm tracker

2.內(nèi)部風(fēng)暴追蹤器

Dogs are sensitive to drops in barometric pressure that come with severe storms, and they can hear low frequencies that humans can’t, like far-off thunder and earthquake rumbles.

狗能感受到強(qiáng)風(fēng)暴引起的氣壓下降，能聽到人類聽不到的低頻率，比如遙遠(yuǎn)的雷聲和地震的隆隆聲。

3. Secret tail code

3.神秘的尾巴密碼

They lower their tails when they feel scared or nervous. When they’re alert or aroused, the tails wag higher. If a pooch is aggressive or feeling threatened, that tail will stick straight up in the air.

狗害怕或緊張時(shí)會(huì)放低尾巴，警覺或受刺激時(shí)尾巴揚(yáng)起。狗要發(fā)起攻擊或感覺受到威脅時(shí)尾巴會(huì)直立。

4. Doggy diagnosis

4.狗狗診斷

Thanks to their powerful sense of smell, dogs can pick up on volatile organic compounds(VOCs) in human bodies, which include diseases like cancer.

多虧了狗狗強(qiáng)大的嗅覺，它們能注意到人類體內(nèi)揮發(fā)性有機(jī)化合物，包括癌癥這樣的疾病。

5. Telepathy

5.心靈感應(yīng)

They can definitely use your facial expressions and tone to pick up that you’re not in a great mood.

它們利用你的面部表情和語氣就能知道你心情不太好。

6. Empathy

6.同情

Not only do dogs and pups understand your feelings, but they can also empathize with you.

狗狗和小狗崽不僅能理解你的感情，還能向你表達(dá)同情。

7. Built-in GPS

7.內(nèi)置GPS

They are able to follow their own scent trails for miles to retrace their steps, and if the wind is right, they can even use their owners’ scent as well.

它們能追隨自己的氣味痕跡幾英里找到自己走過的路，如果風(fēng)向合適，它們甚至也能追蹤主人的氣味。

8. Sonic hearing

8.靠聲波的聽力

While we meager humans can only hear sounds up to 20,000 Hz, dogs can hear up to 60,000 Hz. Plus, they have about 18 ear muscles, which allow them to rotate, tilt, and raise their ears to get an amplified sound.

我們?nèi)祟愇⑷醯穆犃χ荒苈牭?0,000 Hz的聲音，狗能聽到60,000 Hz的聲音。而且他們約有18個(gè)耳部肌肉，使它們的耳朵能旋轉(zhuǎn)、傾斜并豎起來放大聲音。

9. Night vision

9.夜間視力

Their large pupils let more light in, and the rods in their eyes work better in dim light. But the biggest factor is the tapetum, which reflects light at the back of the eye. That helps them see in light that’s five times dimmer than what humans need to see clearly.

狗狗的大瞳孔能吸收更多的光，眼睛中的桿狀細(xì)胞在弱光下也能看得更好。但作用最大的還是照膜，它在眼睛后部能反光，幫助狗在比人能看清的光線弱5倍的環(huán)境下都能看清。

10. Super speed

10.超快的速度

On average, canines clock in at about 19 miles per hour, but many can go over 35 mph if they’re running in short spurts. The fastest dog breed is the greyhound, which can reach 45 mph.

狗能達(dá)到的平均速度約19英里每小時(shí)，但短距離沖刺時(shí)很多狗都能達(dá)到35英里每小時(shí)。速度最快的品種是格雷伊獵犬，速度能達(dá)到45英里每小時(shí)。

11. The best prescription ever

11.最好的藥方

Petting dogs can reduce stress, help your body release a relaxation hormone, and lower blood pressure.

撫摸狗能減壓，幫你的身體釋放一種松弛激素，還能降血壓。
