Everyone knows that if a dog’s ears are up and its tail is wagging vigorously, it is definitely pleased to see you. but now scientists using a robot have found that the way dogs use their tails is more complicated than we thought, and that dogs which wag them to the left may he more friendly. The animal psychologists discovered that when real dogs approached a life-sized robot dog, they were less cautious about it when it was wagging its tail to the left, while if it was wagging its tail to the right, far fewer dogs approached it in a confident manner.

In the first experiments, 56 percent of the animals approached the model without hesitation when the tail was wagged to the left, while only 21 percent did so in the other situation. When the researchers excluded(排除)owners from being present, the result were: 31 percent of the dogs approached continuously when the tail was wagging to the left, while only 18 percent did so when it was on the right.

Animal psychologist Roger Mugford said it added to the growing evidence that does were even more complicated communicators than the animals more closely related to man such as monkeys. He said, “We know that dogs, in a sense, have languages, but it is more complicated because it is not just them wagging their tails, but also giving out chemical displays.”

He adds, “The research confirms earlier studies suggesting that dogs, like humans, had a left-side preference. If yoare going to present a signal to a dog, it is sensible to put it on your left-hand side because that is where dogs, unlike most other animals, tend to look. It is another example of the similarity between dogs and humans. They are a lot more human than we give them credit for.”
