By the time Amy turns 10, it is clear that she has inherited troublemaking traits from her mother. This starts when Amy taunts Simon when his father, Peter Barlow (Chris Gascoyne), is sent to prison for the murder of Tina McIntyre (Michelle Keegan). Whilst being looked after by Sophie Webster (Brooke Vincent) and her girlfriend, Maddie Heath (Amy James-Kelly), Amy becomes jealous of the amount of attention that Simon is getting. After Maddie berates Amy for bullying Simon, Amy sneaks off to see Tracy and lies that Maddie has threatened to hit her. A week later, Simon and Amy are once again looked after by Maddie and Sophie and again, Amy is jealous of the attention that Maddie shows to Simon. When they stop at "The Kabin" to get some sweets, Amy deliberately lets Deirdre's dog, Eccles, off her lead, knowing that the dog going missing would greatly upset Simon. Later, Sophie and Maddie find the dog and return her home to a relieved Deirdre and Simon. In September 2014, Amy causes more trouble when she cuts her hand on the back door and lies that the dog has bitten her. Tracy is furious and insists that the dog must be put down. Simon is devastated and tells Sophie and Maddie about what has happened. Maddie and a reluctant Sophie agree to try to help and they take the dog and hide her in No. 4. The Barlows begin searching for the dog and a couple of days later, Ken spots Sophie and Maddie taking her for a walk. Ken brings the dog home and Tracy again insists that the dog has to go. Ken tries to get Amy to tell the truth about her injury and she eventually reveals that she lied about the dog biting her. Maddie praises Amy for admitting the truth, telling her that she was very brave.
