Canine Hearing

Erect ears, such as those on a German Shepard or a Basenji are more likely to
take in sound than the "flop" ears are as those on a Bloodhound. But, regardless of the ear type, dogs have some pretty good hearing skills. "Hear" are some tid-bits on ears and hearing.

Dogs have an incredible hearing ability. In fact it is their second most developed sense, next to smell.  Your dogs ears are almost pitch perfect. People can pick up an average of 20,000 acoustic vibrations per second (kHz), whereas a dog is able to perceive up to around 40,000 (kHz) and possibly up to 70,000 (kHz).

A dog can hear a sound from 250 yards away. Most humans can*t hear beyond 25 yards.

Chronic exposure to loud noises, such as gun blasts, can injure the sensitive workings of the inner ear, damaging hearing.

Using their swiveling ears like radar dishes, experiments have shown that dogs can locate the source of a sound in 6/100ths of a second.

A dog is born into the world deaf, It's ears closed until about the tenth day. Hearing is fully developed at the age of three to four weeks.

Congenital deafness does occur in dogs and is often associated with white coat coloring. Dalmatians and Australian Cattle Dogs are particularly prone to congenital deafness.
