Boo-Boo (nicknamed Rover) was discovered by Steve McDonald in the back of his Street Cars cab. He took in the dog at his home at the Rovers Return Inn and bonded with her. He later had her scanned, but she wasn't micro-chipped. He later discovered the actual owners were on the other side of the world working on a way to get a ticket back to the UK. Steve nicknamed the dog Rover, as he didn't want to keep referring to her as "Dog". Cookie, who appears as Rover, is in real-life one of Simon Gregson's dogs.
