Realistic black and grey tattoo design of a Labrador's head…

Realistic black and grey tattoo design of a Labrador's head, highly detailed, with a visible shirt collar around the neck. The style should be photorealistic with smooth shading, fine lines, and subtle texture to mimic real tattoo art. The expression is gentle and noble, with detailed fur, whiskers, and realistic eyes. The collar is slightly wrinkled, suggesting a formal shirt. Black and grey ink only, no colors. The background is transparent or white. The composition is clean, focusing only on the dog's head and collar.
