　　Dogs wag (摇摆) their tails in different directions depending on whether they are excited and wanting to move forward or threatened and thinking of moving back, a study has found.

　　Researchers in Italy examined the tail wagging behaviour of 30 dogs, catching their responses to a range of stimuli (刺激物) with video cameras.To conduct the study they chose 15 male dogs and 15 female ones aged between one and six years old.The dogs were all family pets whose owners had allowed them to take part in the experiment at Bari University.The dogs were placed in a large wooden box with an opening at the front to allow them to view various stimuli.They were tested one at a time.

　　The researchers led by Professor Giorgio Vallortigara of the University of Trieste found that when the dogs were shown their owners—their tails wagged energetically to the right side.When they were shown an unfamiliar human they wagged to the right, but with somewhat less enthusiasm.The appearance of a cat again caused a righthand side wag, although with less intensity again.The appearance of a large unfamiliar dog, similar to a German shepherd, changed the direction of tail wagging to the left.Researchers supposed the dog was thinking of moving back.When the dogs were not shown any stimuli they tended to wag their tails to the left, suggesting they preferred company.While the changes in the tail wagging were not easily noticed without the aid of video, it was thought that the findings could help people judge the mood of dogs.Computer and video systems, for example, could be used by professional dog trainers to determine the mood of dogs that they were required to approach.
