What term describes a long, narrow skull shape?

The story behind the answer

Dolichocephalic describes dogs with long, narrow skulls and elongated muzzles—think Greyhounds, Borzoi, and Collies. The term comes from Greek dolicho- (long) + -cephalic (head), so it literally means “long-headed,” making it the correct choice.

Head shapes are grouped by the cephalic index (skull width/length): low index = dolichocephalic; medium = mesocephalic; high = brachycephalic (short, broad faces like Pugs). Long heads in many sighthounds streamline the skull for speed and provide a wide field of view, while extended nasal passages can aid airflow and heat exchange. Memory tip: “Dolly has a long head”—Dolichocephalic.
