The chained goat

Why it is chained? That was my question to the owner when I saw it. The answer was very simple, it attacks anybody. Actually it is very big but it looks small in the picture because of its position. It is a male goat with white color in the body and light brown in the head part. Its horns are sharp and strong and they were its weapons. When I came closer to it with my camera, the goat moves its front legs higher preparing itself to attack me. The owner told me not to go near because it is very strong that is why they chained it. So I back off but I still took a picture of it in a ready to fight position.
