A stray dog at the cemetery gives him a hidden message from his missing son

No one knows how to explain what sometimes happens in the deepest moments of mourning. For Diane, it all started with the silent presence of an unknown dog at her son Ethan's grave. What she didn't know was that this animal carried a secret that had been buried for years — a secret that would change everything.
A silent and unexplained presence
He was still there, faithful as a shadow. A golden retriever mix with a slightly bushy fur, without a tag or leash around his neck. No one in the neighborhood could explain where he came from, or why he chose this burial place out of hundreds. Diane had questioned the cemetery guards, the regular walkers, the neighbors around. Nothing. So she had simply gotten into the habit of giving him fresh water and some kibble. The animal hardly approached. He remained there, motionless, in the pouring rain, in the July sun, in the freezing cold of January.
