The dog hears the sound but we don't.
The human ear can only detect sounds of a frequency between 20 cycle/second and 20,000 cycles/second at the very best. Dogs can hear sounds with a greater frequency. A typical a dog whistle is within the range of 16000 cycles/second to 22000 cycles/second. To put it more technically, a dog's inner ear vibrates or resonates to the high frequency sound waves of a dog whistle but our ears do not.
Its the same with bats, they are constantly sending out high frequency sounds, to locate flying insects but our inner ears don't resonate at those high frequencies and so we don't hear the constant "chirping" sound that they are making.
