Tommy, a 7-year-old German shepherd, used to accompany his owner, Maria Margherita Lochi, to services at Santa Maria Assunta church in San Donaci, Italy and was allowed to sit at her feet.
After Maria died, according to the "Daily Mail", the dog joined mourners at her funeral service and followed after Maria's coffin as it was carried into the church.
Tommy has been showing up at the church when the bell rings out to mark the beginning of services ever since.
"He's there every time I celebrate mass and is very well behaved," Father Donato Panna told the "Daily Mail". "He doesn't make a sound."
None of the other parishioners has complained, Panna said, and villagers give the dog food and water and allow him to sleep nearby writes the "Daily Mail".
"I've not heard one bark from him in all the time he has been coming in," Panna added. "He waits patiently by the side of the altar and just sits there quietly. I didn't have the heart to throw him out—I've just recently lost my own dog, so I leave him there until Mass finishes and then I let him out."
