The American Corgi is a small dog typically standing 23 to 33 cm at the shoulder and weighing between 10 and 15 kg — slightly variable depending on which parent’s size genes are more strongly expressed. The build is the characteristic Corgi type: long-bodied, short-legged, and powerfully muscled for its size. The head is fox-like and expressive; ears are large, upright, and rounded at the tip in the Corgi manner.
The coat may be the standard Corgi double coat or “fluffy” (a longer, softer coat expressing a recessive gene present in both parent breeds). Colors include sable, tricolor, black and tan, blue merle, and red — the last three reflecting Cardigan color genetics unavailable in the pure Pembroke. Blue merle American Corgis are highly sought-after in the US market.
