"Corgi" covers two Welsh herding breeds, the Pembroke and the Cardigan, plus dogs labeled corgi mixes. Both are long, low cattle dogs with upright ears and a dense double coat. Pembrokes are foxier and usually have a short or docked tail, while Cardigans are heavier and keep a long, brushy tail. Size varies, from about 22 to 38 pounds.
Corgis are bright, affectionate and confident, but their herding heritage can show up as barking, bossiness and heel-nipping. In Springfield, that means leash manners and early socialization matter on busy sidewalks and park paths. They shed heavily, love food and need daily exercise, so weight and grooming are steady parts of life with one.
