In 1977, Gnasher was given his own strip in the Beano, Gnasher's Tale, which like the main Dennis strip was drawn by Sutherland. Similarly, when Dennis's pet pig, Rasher, received his own page in 1984, Sutherland was again the strip's artist, as he was when Gnasher's Tale was replaced by Gnasher and Gnipper in 1986. He sometimes draws himself into strips, such as Biffo in the 2010 annual.
