4. Doggy diagnosis

8. Sonic hearing
8.靠声波的听力
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
9.夜间视力
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，眼睛中的杆状细胞在弱光下也能看得更好。但作用最大的还是照膜，它在眼睛后部能反光，帮助狗在比人能看清的光线弱5倍的环境下都能看清。
