The incident happened at 7pm on Tuesday evening in front of Lad Tan Temple in Tambon Don Masang, Muang district.
Passers-by found the body of Boonlert Khamthawai, 63, who was still conscious, and the lifeless bodies of his two dogs.
Rescuers tried to resuscitate Boonlert but he died at a hospital.
Local residents said Boonlert and his dogs walked at the spot every evening but the ground was wet following rains earlier in the day and the two dogs might have been hit by current leakage while the man was also fatally injured while trying to save them.
