狗狗肩高在哪里？
1.测量方法不统一，造成误差很大 首先我们来看看国外犬业俱乐部和繁殖者是怎么定义肩高的吧——（注意看后面都有标注“在肩部最高点量得到的长度”）
美国CFA俱乐部：The height at the withers is measured straight up from the top of the shoulder (at the point where it joins with the neck)， but not including the underline or wither scar， and includes any laydown in rear legs due to age. This measurement may vary slightly by breed，but should be within one inch of identical measurements taken on both sides. The height at wither means that a “level line" drawn between the shoulders will include only 1 inch of the back which juts out more than an inch above this level， or will drop below the elbows。 这说的是肩高点与腰节点的距离，不是肩峰的高度。肩峰太高会造成体形偏胖；太低则显得身体瘦长。所以肩高是介于这两种情况之间的一个数值。
英国KC/ARO协会：Height is measured vertically from the highest point on the withers to the floor， measured as if the dog were standing on two feet with both hindlegs fully extended. For some breeds this can be over one inch higher when they stand in their normal stance， so care must be taken with measurements made in this way. It's important to note the difference between height and overall height- for example，the Corgi is described as having a "low body type" while the Dachshund has been given a "tall body type"， even though each has exactly the same height！ 这说的是肩高中枢高度，跟前面的测量方法一样，都是要量到腰部最低处。值得注意的是，有的犬种头部会很高，所以看上去会像身材矮小，比如西施、比熊等小型犬，但它们实际肩高并不小的哦~
2.公母差异大 这个很好理解，雌性犬的骨盆宽于雄性的，因此腹部会下垂得比较厉害。以贵宾为例，成年母的肩高一般不超过38寸，而雄的则可达40多。还有一只著名的巨型贵宾叫Gizmo，肩高竟然达到惊人的65！！！这已经快赶上大型犬的尺寸了……
