A dog named Sienna was found as a stray on the streets of Altavista, Virginia. She then went into care at the Campbell County Animal Care and Control Facility, and no one came forward to claim her. Sienna was being walked at a public adoption event last weekend when she was strangely drawn to a man sitting down. He hadn't called her, and he didn't know the dog. But Sienna sat down and placed her paw on his foot. Then she pawed at his leg and sat down again. The man's wife appeared and thought the scene a big odd, then she realized that her husband was about to have a seizure. She was able to get him to their car and take care of him.
Sienna's behavior was exactly that of a dog who had been trained to detect and alert for impending seizures. But why would a dog with such training be abandoned? Is it possible that Sienna is so sensitive that she would warn a stranger even without training? At any rate, Sienna has been hailed as a hero, and she has received donations for veterinary care and several adoption applications. -via Fark
