Taming a Wolf

Most dog owners can easily differentiate between "I want to go out," and "Somebody's out there," as well as other barks conveying happiness, annoyance or even fear.

Small dogs, such as the toy fox terrier, are usually the most vocal of domestic canines, seeming to make up with volume and persistence what they lack in size.

The wolf emits a howling whistle to communicate with its brethren while they circle prey in the undergrowth, enabling the group to coordinate the attack.
