Happy Tail?.. Or Sad Tail?..

By: Skylar Warde


New Italian scientists, have found that when a dog wags his/her tail they can show a sign to the other dog. They found this out by hooking a dog up to a machine, and showing them a video. The first one is a dog wagging their tail to the left, which got the other dog nervous. The second video is a dog wagging its tail to the right, and the other dog stays calm.
