Last month we went out for dinner, and on coming back, I noticed a dog chewing something. I assumed it would be the leftover treats he was chewing even though he had finished the meal we served him before leaving. I almost forgot about that later on. Then, a few days later, I found my dog chewing again in the park, and I checked his mouth to see if he had eaten something that he shouldn’t have. But there was nothing that was chewing on. It was something I never saw him do earlier. And I wondered why is my dog chewing with nothing in his mouth?

Most people I asked mentioned coming across such a situation now and then. But most people quoted different reasons for the same.
