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.
Gnasher's solo comic strip debuted in the Beano in 1977, illustrated by Sutherland, similar to the main Dennis strip. Later, when Rasher, Dennis's pet pig, had his own page in 1984, Sutherland drew it again, just as he did when Gnasher's Tale was replaced by a new duo, Gnasher and Gnipper, in 1986.
