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 received his own comic strip in the Beano in 1977, illustrated by Sutherland, which was comparable to the main Dennis strip. Subsequently, when Rasher got his own page in 1984, Sutherland drew it once more, just as he did when Gnasher's Tale was replaced by a new pair, Gnasher and Gnipper, in 1986.
