[简介]

    这是一种活跃的、爱玩的、勇敢的、小型工作梗，属于短腿类；其动作轻松、有力，身体结构不沉重，从前面看，腿很好地支撑着身体，肋骨深，与后躯结合良好，显得结实而且比例匀称，背长中等，具有粗硬而且能抵抗恶劣气候的被毛；头部比其他梗类犬短且宽，长有浓密的毛发，使表情显得狡猾。

[头部]

    头颅：与长度相比，显得宽阔，止部明确，头顶长有许多毛发，毛发也许比身体上的被毛软一些。
    口吻：结实，但不能太长，或太重。
    牙齿：大，不能是上颚突出式咬合或下颚突出式咬合。鼻镜为黑色。眼睛位置分的很开，下陷，长有浓密的眉毛。
    眼睛：大小中等，浅褐色或深褐色，或与身体颜色匹配，具有梗类犬典型的热情眼神。 
    耳朵：小，立耳，位置分的很开，位于头部两侧。从长长的毛发中露出来。

[颈部、背线、身躯]

    肌肉发达、结实、有活力，身体健康，肋骨深，与结实的后躯结合，背部水平，中等长度，给人的印象是结实、有活力而不沉重。
    肩部倾斜，腿长度中等，骨量充足但不厚重；前肢的肘部不外翻，应该是非常完美的垂直，但前足爪也许略呈外八字。后足爪比前足爪大一些。腿上必须长满粗硬的毛发。脚垫应该厚且结实，牢固地支撑着狗的全身。
    尾巴：与头部比例恰当，长有大量毛发，但没有饰毛。尾巴欢快地举着，但不能卷在背上。尾根位置与背平面齐平。

[被毛]

    坚硬且能抵抗恶劣的天气。必须有两层毛：浓密、粗糙的披毛和短、柔软、浓密的底毛。

[颜色]

    可以是除了白色以外的任何颜色。耳朵、口吻及尾尖必须为深色。

[体型]

    包括体重、肩高、体长。母狗体重为13磅；公狗体重为14磅。母狗肩高约9.5英寸；公狗肩高为10英寸。体长约14.5~15英寸。必须比例匀称，腿既不能太长，也不能太短。这一体重标准是对成年狗（2岁）而言，年龄大的狗也许更重些或年龄更小些的狗也许轻一些。
    特点：应该显得肌肉发达，既不太胖也不太瘦。头上长有大量毛发，耳朵尖、尾巴和足爪整洁、呈绒球状。步态轻松、不费力，只需要稍稍牵引，无须操纵。用足尖站立，显现出梗类犬特有的表情。

[缺陷]

    1、 头颅太窄。 
    2、 口吻太长而且嘴脸太重。
    3、 眼睛太大，突出、黄色、呈环状都属于缺陷。
    4、 耳朵太大、耳尖太圆、位置太近、太高；被过重的毛发遮盖。
    5、 腿和足爪的骨量太重或太轻。前肢弯曲或肘部外翻。足爪薄或似貂爪。足爪的后跟太靠下，分的太开。腿太长或太短。
    6、 身躯，背太短且紧接身体，影响行动和转身。太长，象蛇一样的身躯，显得虚弱。尾巴位置太低。背线不平。
    7、 被毛，被毛松散、被毛杂乱、太短或死板的被毛、缺乏足够的底毛、头部缺少足够毛发、腿部缺少足够硬毛。柔软或卷曲的毛发。轻微的波状毛是允许的。
    8、 肉色或浅色鼻镜。

Length of body from 14¼ to 15 inches from the front of the chest to back of hindquarters. The dog must be of balanced proportions and appear neither leggy nor too low to ground; and neither too short nor too long in body. Weight and measurements are for matured dogs at two years of age. Older dogs may weigh slightly in excess and growing dogs may be under these weights and measurements.
