(CBS) — A Chicago woman who loved and lost her dog has an amazing story to share.

Ashley Lang’s beloved golden retriever Wagner died at 12 years old. When she spread his ashes, something strange happened. A friend snapped a picture on a iPhone, which captures what looks like a white silhouette of a dog.

“It’s pretty remarkable…the tail and the legs and he looks like he’s, you know, leaping to go up,” Lang said. “Everyone keeps calling him the angel dog.”

Lang says she thinks the photo is Wagner’s way of saying a final goodbye.
