I’ve always known that dogs are clever, but even I was surprised when I heard about a dog called Red, at the Battersea Dog’s Home in London.

The home has been caring for lost and unwanted animals for over 140 years. Recently, the workers there got amazed when they came to work in the morning. They found that some of the dogs had got out of their kennels(狗窝) during the night, opened cupboards and taken out of food and toys. And it happened again, and again. The manager described how as many as nine dogs were escaping every night. “When we came in, dogs were running around having fun and games and causing a lot of mess. We couldn’t understand it.”

Someone or something was unlocking the kennels during the night. The manager decided that the only way to know the truth was to put in cameras to record how the dogs were getting out.

When she and her workers played back the recording, they saw Red, a three-year-old dog, put his nose through the bars of his kennel and use his teeth to press the button that opened the door. That was clever enough, but Red did more: he unlocked the kennels next to his and let the dogs out too. The group broke into cupboards and stole dog biscuits and toys to play with.

The manager said, “It’s surprising that Red worked out how to open his own kennel, but also that he then let all his friends out.” I suppose, Red didn’t like to party alone.

The story has a happy ending: after Red was shown on TV, several people came and offered to give him a new home as a family pet.
