I love that show "Miracle Pets" that comes on Pax TV. It has the same type of stories - for instance, a Vietnamese pot-bellied pig rescued his mom after she fell unconscious in her home. He knew something was wrong, and kept going in and out the dog door for help. He was too big for the dog door, though, and each time he went through he scraped his back up pretty badly. But he kept going in and out anyway. Finally a workman drove up in the street, and the pig jumped up on his truck to get his attention. The man could tell the pig was agitated, so he followed him and discovered the ill woman and called 911. I watch it fairly often, but this is the only story I can remember off the top of my head.
