O’Dwyer, who trains guide dogs, told ITV’s Lorraine show that it was another dog called Chase who walked the tightrope because Matisse is afraid of heights.
The sketch featured O'Dwyer dressed as a policewoman going after Matisse, who had stolen sausages from a butcher, and also featured another of her pets, three-legged Skippy.
Viewers saw Matisse emerge back on to the stage after he appeared to have walked along parallel ropes, but it turned out that a second border collie had performed that part of the stunt.
She added: ”The tightrope takes months of training. It takes a special rigging system. It takes professionals to help you. BGT were fabulous. Our team said what we needed to pull this off.”
But others were less at ease with the decision to use an unnamed stunt dog:
A spokesman for the producers of Britain's Got Talent said:
“The audience had previously seen from Jules’ semi-final routine that she works with a second dog Chase alongside Matisse. For the final performance, as Jules has said publicly herself, Chase completed the tight-rope walking section of the act.
“During the competition viewers have seen that Jules' act involves a team of dogs, including Chase and Skippy, alongside starring dog Matisse, to perform her unique mixture of dog agility and story-telling. We are sorry if this was not made clearer to the judges and viewers at home during their final performance.”
