In dog grooming, what does "Penciling" refer to?

Penciling specifically refers to the technique in dog grooming that involves creating distinct black lines that separate the tan markings on a dog's toes. This is particularly common in breeds with tan and black coloration, where a clean and defined line enhances the overall appearance of the dog's coat.

By adding these lines, groomers can accentuate the dog’s features, making the markings more pronounced and visually appealing. This technique requires precision and a good understanding of the breed's standard coat markings, which is why it is an important part of grooming practices for certain breeds.
