The Pembroke Welsh Corgi has erect ears that are in proportion to the equilateral triangle of the head. The breed standard indicates that the ears should be firm, medium in size, and tapered slightly to a rounded point. The head should be 'fox-like' in shape and appearance. Pembroke Welsh Corgis differ from the Cardigan Welsh Corgi by being shorter in length, having smaller ears, and being slightly straighter of leg. The Pembroke Welsh Corgi has a 'fairy saddle', somewhat lighter markings on each side of the withers caused by changes in the thickness, length, and direction of hair growth. The Pembroke Welsh Corgi sheds mostly in the spring and autumn and may shed annually, with intact females shedding during heat.
