What term describes a short, flat-faced skull shape seen in some breeds?

The story behind the answer

Brachycephalic describes dogs with a shortened skull and muzzle, giving a flat-faced appearance—think Pugs, Bulldogs, and French Bulldogs. “Brachy” means short and “cephalic” means head. This head shape results from selective breeding and is measured by a high cephalic index (skull width relative to length).

Why it matters: brachycephalic dogs are prone to breathing difficulties (brachycephalic obstructive airway syndrome), heat intolerance, dental crowding, and eye issues due to compressed facial structures. By contrast, dolichocephalic breeds (Greyhounds, Collies) have long skulls, and mesaticephalic breeds (Beagles, Labradors) are mid-range. “Platycephalic” isn’t a standard canine category. Memory tip: B for Bulldog/Boxer = Brachycephalic.
