Before I found out that Shrek has gone missing, his owner (an indian boy) asked me whether I've seen him or not, it was unusual that Shrek did not return to his owner for one whole day. Even now that I know why Shrek gone missing, I will keep this cruel fact from him, he's still a very young boy, can he take it?
From Mary's descriptions, Mary was cruelly dragged along the street to the execution spot (which is near to Mary's house), she suffered from cuts and bruises. She was in shock for few days, keeping herself within her house without stepping out.
Her owner decided to keep her within the house compound, to avoid the same tragedy. There was a time when Mary managed to escape, her owner found her sat still in-front of Shrek's house. I bet she missed her best playmate.
Shrek had been a good boy all this while, playful and energetic. We had some fun moments with him since he was a puppy. We missed him, and hope that he enjoys himself in dog's heaven.
