Graham and Rose were looking for a new dog, they seen an ad for the talking dog in question. It was put up for sale by its owner up in Inverness. They travelled up to Inverness, met the owner, who then confirmed the dog did actually talk. Graham went up to the dog asked if it talked. The replied ‘Yes’. Shocked but not taken a back Graham asked for the dog to tell them about itself.
The dog when on to say, that he started out his earlier life as a model, featuring in various television commercials. This is where he was picked up by his agent and moved over to Los Angles in America and starred in a few Hollywood films. He got roles working alongside various actors including Tom Hanks. The CIA heard about him and temporarily enlisted his services as a spy and was then sent over to Russia. He went on to say that the details were classified so he didn’t go into too much detail. After leaving the CIA he retired in Inverness.
Although Graham and Rose were impressed, they decided against bringing the dog back to Perth as they thought it was a liar and fabricated its stories.
