Dogs wag 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 with video cameras To conduct the study they chose 15 made dogs and 15female ones aged between one and six years. The dogs were all family pets whose owner had allowed them to take part in the experiment at Ban University .The dogs were placed in a large woode 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 Gilrgio Vallortigara of the Trieste found that when the dogs were shown their owner-a positive experience-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 right-hand side wag,although with less intensity again. The appearance of a large unfamiliar dog, similar to a German shepherd,changed the direction of tail eagging to the left.Researcher supposed the dog was thinking of moving back. hen the dogs were not shown any stimuli they tended to wag their tails to the left, suggesting they preperred company. While the changes in the tail wagging to were not easily noticed without the aid of video ,it was thought that the findings in the tail wagging were ont easily noyiced without the aid of video,it was thought that the findings could help 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 appreach
