Which episode between 1988-1995 had a man in a basement flat welcomed bởi a small white dog?

This was my grandmothers flat and I vaguely remember the bill filmed in her 2 giường basement flat in Clapham and the producers liked her dog so much he was allowed a part. I never got the oportunity to watch it as a child so have no other info but would tình yêu to see it now as an adult.
