Gnasher

Gnasher is a fictional dog from the British comic strip Dennis the Menace, created by David Law. Gnasher is Dennis's best friend and constant companion, a scruffy black dog with a distinctive habit of biting. He is known for his loyalty to Dennis and his mischievous nature, often participating in or instigating pranks with his owner.

Gnasher is characterized by his sharp teeth and a tendency to chomp on anything that annoys him or Dennis, including adults like Mr. Wilson, Dennis's long-suffering neighbor. Despite his aggressive name and behavior, Gnasher is depicted as a loving pet to Dennis, who often relies on Gnasher's strength and willingness to get into trouble.

The character of Gnasher was introduced a few years after Dennis himself, becoming an integral part of the comic strip's enduring appeal. He is a visual gag in himself, often depicted with exaggerated expressions of anger or excitement. Gnasher's presence amplifies Dennis's own rebellious spirit, making them a formidable duo. Over the years, Gnasher has appeared in various adaptations of Dennis the Menace, including television shows and films, solidifying his status as one of the most recognizable comic strip pets.
