Have just worked out why the Puppy was scratching at the settee. Underneath were a number of a sorted size balls to play with, and Dougal was just trying to get at them to play. However, the smart little sod has also worked out (and I have seen him do it) he rolls his favourite ball back under the settee so he HAS TOO go after it. A win win for Dougal. 1: He gets to try and eat the Settee and 2: The stupid Humans will get down on the floor and try and get his ball back (and they also stay and play)
