Studies have shown that dogs are capable of perceiving frequencies about twice that of a normal human and can pick up and distinguish sounds roughly four times that of humans. This means that dogs can hear many sounds on frequencies that humans cannot even begin to detect and what a human can hear at 20 feet a dog can hear at roughly 80 feet. read more

Another reason is that the frequencies that dogs hear are much higher and lower than what humans can hear. Dogs hear a frequency range of 40 to 60,000 Hz while a human range is between 20 and 20,000 Hz. read more
