The final episode should be Wallace being euthenised by a sympathetic carer in a cancer hospice, while Gromit's taken to the vets to be put down, as old dogs just don't get taken home by visitors to pounds; often being overlooked for younger, cuter, less "beady-eyed" ones that haven't been "broken in" yet. The final shot would naturally be their respective corpses entering the crematorium furnaces. Their plasticene bodies melt, dripping down through a series of grates until they congeal to form the word "Fin", followed by a fade to black and the end credits.
