It's on the Dominican Church wall.
Dog with a torch is one of Saint Dominic's attributes.
According to the Legend, St. Dominic's mother while pregnant, had a dream that she would give birth to a dog who would hold a torch in its mouth and would "burn the world."
It has been suggested that the dog represents a pun on Dominicanus, the word for a Dominican friar, and Latin phrase domini canis, "dog of the Lord."
At any rate, a dog is often shown at the saint's feet holding a torch in its mouth.
It also became the symbol for the Dominican religious order.
