The horses， donkeys and dogs who arrive at Horse Creek Stable Rescue Sanctuary are often sick， weak or just tired. Lester Aradi， a retired police chief， along with his wife Diane， makes sure of their conservation. The refuge （收容所） for special needs animals they founded in Georgia’s Blue Ridge mountains is a 35-acre beacon of new beginnings. But there are endings here， too.

When they die， the animals are buried （埋葬） on a slight hillside overlooking the grassland. Graves （坟墓） for dogs are lined up in a row. Burials for bigger animals—horses， donkeys—are marked with a fruit tree. Lester and Diane see it as a symbol of the circle of life. “We just try to honor them that way，” Lester said. But the most obvious marker for a fresh grave will be a three-legged dog named Tricycle. When an animal dies， he subsequently shows sadness—sometimes for as long as three days.

“I don’t know if he can sense it， smell it， or whatever， but he looks sad. That is his way of saying goodbye.” He first looked like this when his friend Major died. “When Major died， we buried him here on the farm，” Lester said. “Tricycle went over and lay on his grave for about three days. He would come into the house. But every time he was outside， he would go to Major’s grave and lie on it.”

Lester posted a picture of Tricycle mourning Major on Horse Creek Stable Rescue Sanctuary’s Facebook page. Not long after that， a dog rescue group got in touch with him. They thought maybe Lester and Diane could take in another three-legged dog who needed a second chance in life. And so， Romeo arrived at the farm. Naturally， Tricycle bonded with his new friend， just like him. It is truly the circle of life.
