Every day for a week, a strange, happy visitor would drop to play with Vanessa Prior’s pet dog Bobby. Prior thought Bobby had made a new dog friend. It seemed very friendly and got well along with Bobby. They would run after each other, play on the pool cover, gently wrestle (摔跤) or nap side by side.

At first she thought it was a wild dog. But when she posted a photo of the two playing on her Facebook, a pet rescue centre called her. The group told her the Atlanta Wolf Project had been trying to catch the wolf for months, but they failed. Prior gave them new hope.

Because of the wolfs friendship with her pet dog, it was likely to come back to her backyard. Researchers hoped Prior could help them. When they put some traps (陷阱) in the back of her yard, Prior got a very complicated (复杂的) feeling. She couldn’t describe what it was. The wolf would be in a safe place, but she would do something that harmed Bobby’s feelings.

Researchers told Prior that they would take the rare, black wolf to the Yellow River Wildlife Sanctuary where it would live with another wolf. They didn’t think it a satisfying situation for a wild animal like a wolf to have a connection with humans’ life. They need to keep a natural awareness to humans and pets and keep to themselves.

Wolf experts added they would look into the genetics of the animal to try to learn why it liked to get close to people and tried to play with their pets. Some experts believe it could have a history with well-meaning humans. Prior had not expected that she and Bobby should meet such a special and lovely wolf. They just hoped the dear friend all the best.
