The Isle of Dogs is an area in the East End of London that is bounded on three sides (east, south and west) by one of the largest meanders in the River Thames. The northern boundary has never been clearly or consistently defined (the name Isle of Dogs had no official status until 1978, with the creation of the Isle of Dogs Neighbourhood by Tower Hamlets Borough Council), but many accept it to be the (former) line of the West India South Dock.
