What expression should the small, dark, deep-set eyes of the Welsh Terrier convey?

Answer

Intelligent, keen, and full of terrier spirit.

The eyes of the Welsh Terrier are small, dark, and set somewhat deep into the skull, and the impression they create is vital to judging the dog's disposition. The required expression is one that communicates alertness, mental acuity, and the characteristic liveliness associated with the terrier group. Therefore, the eyes must appear intelligent and keen. An expression lacking this spirited quality, or eyes that exhibit undesirable light or yellowish pigmentation, detracts significantly from the breed's intended alert and spirited look.
