The Collie is a lithe, strong, responsive, active dog, carrying no useless timber, standing naturally straight and firm. The deep, moderately wide chest shows strength, the sloping shoulders and well-bent hocks indicate speed and grace, and the face shows high intelligence. The Collie presents an impressive, proud picture of true balance, each part being in harmonious proportion to every other part and to the whole. Except for the technical description that is essential to this Standard and without which no Standard for the guidance of breeders and judges is adequate, it could be stated simply that no part of the Collie ever seems to be out of proportion to any other part. Timidity, frailness, sullenness, viciousness, lack of animation, cumbersome appearance and lack of over-all balance impair the general character.
