The rust-coloured tracks under a Yorkshire Terrier's eyes are tear stains. They are common on light faces, easy to stain further if you clean them badly, and sometimes a sign that the eye is irritated rather than just "how Yorkies look."
The brown is not dirt. It is porphyrin, a pigment in tears and saliva that oxidises on the hair. This guide covers why it happens, how to clean it without making the skin worse, and when it needs a vet instead of a wipe.
