A dog is prepared to attend competition at the Sarajevo international dog competition in Sarajevo, Bosnia-Herzegovina, on July 19, 2013. Dogs are commonly hailed as "human's best friend", and assist people in many ways. Let's review the moments brought by dogs to greet the approaching Chinese Lunar Year of the Dog. The Chinese Lunar New Year, also known as the Spring Festival, falls on Feb. 16 this year. This year's celebration will usher in the Year of the Dog. The dog comes 11th in the 12-animal zodiac rotation used by the Chinese to represent the year. (Xinhua/Haris Memija)
