1. Super sniffer
Dogs’ sense of smell is 10,000 to 100,000 times more sensitive than that of humans.
2. Internal storm tracker
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.
3. Secret tail code
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.
4. Doggy diagnosis
Thanks to their powerful sense of smell, dogs can pick up on volatile organic compounds (VOCs) in human bodies, which include diseases like cancer.
They can definitely use your facial expressions and tone to pick up that you’re not in a great mood.
Not only do dogs and pups understand your feelings, but they can also empathize with you.
7. Built-in 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.
8. Sonic hearing
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.
我们人类微弱的听力只能听到20,000 Hz的声音，狗能听到60,000 Hz的声音。而且他们约有18个耳部肌肉，使它们的耳朵能旋转、倾斜并竖起来放大声音。
9. Night vision
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.
10. Super speed
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.
11. The best prescription ever
Petting dogs can reduce stress, help your body release a relaxation hormone, and lower blood pressure.
