The story of Gelert.

This story takes place in a castle in Wales many years ago.
This story is about a dog called Gelert and his man Llewely.
Many years ago, the prince's wife died on child-birth. Llewely always considered his dog his best friend so a day, when the knight went out hunting, he left his son in the care of Gelert. Next, when he returned, he found a lot of blood everywhere. After that, he saw Gelert covered of blood and the knight thought that he killed the baby, so he killed the dog. The knight heard the baby crying and saw a dead wolf. The dog killed the wolf and protected the baby.
Gelert's body was buried outside the castle walls. On the headstone, is written "Brave Gelert's grave".
The author's theme is the friendship between an animal and a man, but also not to judge at the first sight.
