Whenever people think that animals do not have feelings, they surely would not have been close to an animal ever. Even if people spend a few minutes with animals, they will get to know their emotions and also understand them better. A stray dog died due to car running on it. But its friend grieved its death and you will be spell-bound looking at the display of emotions by its friend.
Many other people came, saw the dead dog and left. However, this dog stayed all the while with it till it was taken away. Who said only humans can love each other?
