When elephants retire, many head for the Elephant Sanctuary in Hohenwald, Tenn. "Every elephant that comes here searches out someone that she then spends most all of her time with," says sanctuary co-founder Carol Buckley. It's like having a best girlfriend, Buckley says -- "Somebody they can relate to, they have something in common with." But perhaps the closest friends of all are Tarra and Bella. That would be Tarra the 8,700 pound Asian elephant. And Bella. The dog. Most of the stray dogs at the sanctuary want nothing to do with the elephants and vice versa. But not this odd couple, as seen in this touching video. In fact, when Bella was left immobile with an injury for three weeks, Tarra refused to leave.
