There are no wrinkles between the ears. The stop is slight. The flat, clean cheeks are never bulging. The muzzle is one-half the length of the entire head, measured from the tip of the nose to the occiput. The strong, squared-off muzzle is never snipey.
Lips are black and tight.
A level bite is acceptable. The teeth are set in powerful, viselike jaws. The small, almond-shaped, dark brown eyes are well set in the skull, and placed fairly far apart. The size, shape, color and position of the eyes give the steady, confident but alert expression typical of the Welsh Terrier. The small, V-shaped ears are not too thin.
