推荐回答(4个)
回答1:

2个月以下 | 仅有乳齿(白、细、尖锐)
2-4个月 | 更换门齿
4-6个月 | 更换犬齿(白、牙尖圆钝)
6-10个月 | 更换臼齿
1 岁 | 牙长齐,洁白光亮,门齿没有尖突
2 岁 | 下门齿尖突部分磨平
3 岁 | 上门齿尖突部分磨平
4-5岁 | 上、下门齿开始磨损呈微斜面并发黄
6-8岁 | 门齿磨露齿根、犬齿发黄磨损唇部
--------------------------------------------------------
狗的牙齿磨损情况与年龄有关,年龄越大,磨损越严重。但也要看到这与动
物的食物性质有很大关系,如经常吃软食与经常啃骨头,狗的牙齿磨损情况就不
一样,因此只能做为参考。
2、面部表情 年龄在1岁左右的狗,表情活跃,目光有神、好动。2—4岁
的狗,亲切近人,精神焕发、热情。大于7岁的老狗,精神迟顿,对刺激反应迟顿
,不愿多动,眼睛无神。
3、体态 年青狗活动时身体轻巧灵便,2—5岁时活动有些笨拙,但稳当、
安全可靠。10岁以上的老年狗,举止迟顿,脊背伛曲或屈背,走路缓慢。
4、老年毛的发生 指灰白毛的出现(即原来非灰色毛的狗变为灰白毛),
首先发生于唇区、下颌区。4—5岁的狗开始见到少数几根白毛,5—6岁时明显增
多,以后漫延到背部、鼻周围、眼睑、眉毛等处,再进一步扩展到额部及外耳道
内长白毛,甚至整个头部毛变白。超过10岁的狗额部、脸部及头颅的前面有多量
白毛。超过13岁整个头部变成白色(也有个别狗10—14岁时,毛色仍不变)。对
白色、黄白毛或栗色带白斑毛的狗,不能用毛色改变做为年龄判断的辅助手段。

5、眼神 年青狗眼睛有神明亮,7岁以上的狗眼睛出现白内障,8岁以上白
内障发生率多,9—10岁的狗大多数有白内障,10岁以上的狗,几乎全部都有白内
障。早期白内障水晶体呈蓝绿色环。典型的呈中央性或中央周围性白内障,晶体
混浊呈灰色或灰白色,并有明显的绿色折光反射。个别狗1—1.5岁也有患白内障
的。

回答2:

判断一只狗狗的年龄,主要看狗牙齿的磨损和脱落情况,当然还要参考其面部表情,体态,皮毛等情况。 

1、当狗1岁时,所有的牙齿生长完成;

2、2岁时,有些犬齿己积有齿结石。

3、3-4岁时,可以很明显地看到齿结石和牙齿的污垢,下颚的门齿逐渐磨 损。

4、到了5 岁左右,齿尖始磨损。

5、6岁左右,齿结石的量已经相当多了,犬齿也开始衰弱。

6、7-8 岁时,牙齿开始松动,下颚的门齿将被磨成圆形。

7、到了10岁之后,患有齿槽脓漏的门牙开始脱落。
