Corgi is a shared name for two separate Welsh herding breeds, the Pembroke Welsh Corgi and the Cardigan Welsh Corgi, and shelters also use it for corgi mixes. Both are long, low cattle dogs with upright ears, a dense double coat and surprising athleticism. The Pembroke is the more familiar, foxy-faced dog, usually red, sable or tricolor with a short or docked tail, while the heavier Cardigan always keeps a long, brushy tail and can also be brindle or blue merle.
Most corgis are bright, alert and affectionate, with big-dog confidence in a compact body. Their herding heritage often shows as barking, bossiness and nipping at moving heels, especially in young dogs. They shed heavily, enjoy food a little too much and need daily exercise, but for many households they make lively, devoted and entertaining companions.
