Does a puppy have a heart?

Today my Dad left the house on some errands, while he was gone his puppy, Maximus, cried while carrying around the bone that my Dad had given him before he left. The dog cried and cried, moped around and all the while carried his bone from place to place around the office. As I watched Maximus, I realized that he has a heart, a big one. His heart recognized the absense of his best friend and just couldn't cope with life as a result, not even to eat a yummy bone.

I understand Maximus' heart. This is how I feel today.

Isaiah 53 tells me that Jesus was "acquainted with grief...Surely he hath borne our griefs, and carried our sorrows."
