The Elephant Sanctuary south of Nashville is more than 2,000 acres of freedom for elephants. But for a resident named Tarra, there's not enough room in Tennessee to escape the bad news she got last week. For nearly a decade, Tarra had been best friends with a dog named Bella, a mutt who wandered onto the sanctuary grounds and into the heart of the gentle giant. They were so close, in fact, that when Bella got injured a few years ago and had to spend three weeks recuperating in the sanctuary office, guess who held vigil the entire time? Twenty-two hundred acres to roam free, and Tarra just stood in the corner waiting. Home video of their reunion shows how inseparable they'd become and remained, right to the end. Last week, sanctuary workers found Bella's body. By all indications she'd been attacked by coyotes. Where they found Bella is not where she was attacked. When I looked around ... there was no signs of an attack here," said director of elephant husbandry, Steve Smith. "And Tarra, on the underside of her trunk, had blood - as if she picked up the body." Steve's theory is Tarra carried Bella possibly a mile or more to bring her home. [The sanctuary's CEO Rob] Atkinson said the elephants are ... spending more time with Tarra and being extra nice - making gestures like giving her a portion of their food. Of course, anyone who's lost a dog knows you can't eat your way out of the grief - as much we might try - but still nice to know at least Tarra's not alone in this. It's also nice to see that compassion is much more than just human.
