Corgi is the shared name for two Welsh herding breeds, the Pembroke and the Cardigan, and shelter listings may also include corgi mixes. Both are long, low cattle dogs with upright ears and a dense double coat. Pembrokes are lighter and foxier, often red, sable or tricolor, while Cardigans are heavier, always keep a long brushy tail, and can be brindle or blue merle.
Most corgis are alert, affectionate and confident for their size. Their herding background shows up as barking and nipping at moving heels, so early training helps. They shed heavily year-round, love food and gain weight easily. In Sacramento, that means regular brushing, measured meals and walks that fit around the valley heat. Dogs vary, so spend time with each one to see how it behaves.
