 The ninth series became notable for the controversy surrounding the performance of Jules O'Dwyer, and in particular the routine of her dog tricks act in the final.The nature of the complaint focused on the fact that while O'Dwyer had been clear that her occupation involved training and use multiple dogs for her routines, she hadn't disclosed the fact that she had to use two dogs with similar appearances for the final, as her main dog Matisse was unable to perform a trick involving a tightrope section.When this came to light in an interview the morning after the final on 1 July 2015, Ofcom were forced to launch an investigation after 1,000 complaints were raised by viewers who felt misled by the performance's broadcast.
