One hot summer afternoon, Barbara Simmons fell on the side of the road while checking her mail. Simmons, who is 78, called for help for nearly 30 minutes with no luck—until Thor heard her. The Pitbull-Rottweiler mix that belongs to her neighbors gently approached Simmons to investigate the situation. Once he saw that she was in danger, he ran home and alerted his owners that something was wrong. When they didn’t respond right away, he ran back to where Simmons was laying with his owners in tow. They called 911 and the EMT who arrived on the scene told Simmons that Thor probably saved her life.

“He was just so gentle and like, ‘are you okay, are you okay?’” explained Simmons.  “It was like somebody asking, ‘are you okay, are you okay?’”

Despite being part Pitbull and part Rottweiler, Thor has never attacked anyone or harmed anything.

“He’s totally destroyed the stereotype you have of those breeds,” said Thor’s owner, Colin Heaton.  “He loves people.”

Thor’s owners say dogs like him, which are rescued from bad situations, make great pets and their previous living situations don’t really have an impact on the dog’s behavior.

“He has on occasion saved our chickens from a fox, survived being bitten by a copperhead, wrestled another fox, chased a coyote away, and learned dozens of words and commands,” Thor’s owner Anne Lewis said.
