Communication
Effective communication is essential for the formation and maintance of social relationships. Dogs same as wolves have three main methods of communication: auditory, visual and olfactory.
Auditory communication
Auditory communication may be employed over a range of distances and is particulary useful when vision is impaired, for example in thick vegetation. Range of signals given by wolves have also been recorded in domestic dogs. They include diverse range of sounds from grunts, whines, yelps and screams to tooth snapping, coughing, growling, and of course barking.

Effective communication with sound requires an auditory system that can both recieve and decode sound signals. Dogs have relatively ordinary hearing abilities compared with other mamals. Their sensitivity at low frequencies is generally similar that that of cats and humans. At higher pitches, dogs become increasingly more sensitive than humans. The upper frequency limit of hearing in four dogs did not vary with their size, indicating that high-frequency sensitivity may be a species typical characteristic.
