    Q. Why do pigs can't look up straight to the sky?

    Ans. It is physically impossible for pigs to look up straight to the sky. It’s the anatomy of their neck muscles and the spine that limits the movement of their head and restricts them to look totally upwards. Even to look at a tree top, a pig has to take one or more steps back while lifting its head to see directly above it.
