Intense Chihuahua Digital Illustration

A dark, high-contrast digital illustration of a Chihuahua in an aggressive stance, mouth open and teeth visible, similar to a guard dog or attack dog. The style should be monochromatic (black, gray, and white) with a gritty, rough texture, resembling a screen-printed or stencil effect. The background should be transparent or white. The lighting should emphasize the highlights on the dog's face and body for a metallic or high-shine effect. The overall feel should be intense, powerful, and slightly distressed.
