狗狗肚子上有黑斑点是怎么回事

wsrfsrfer

[color=rgb(102, 102, 102) !important]狗狗肚子上有黑斑点可能是由于黑色素沉积、细菌，真菌感染引起的皮肤病、寄生虫感染、长时间没有洗澡清洁、基因遗传等因素引起的。如果狗狗没有其它异常症状，则很可能是黑色素沉积、长时间没有洗澡清洁或者出生时皮肤上就有黑点，那么就不用过于担心。但如果还伴随有皮屑、脱毛、藓斑等症状，可能就是感染细菌、真菌、寄生虫等皮肤病造成的，建议立即咨询宠物医生用药治疗。

当狗狗年龄大了，黑色素沉积严重，所以肚子上就会长出黑斑点，也是俗称的“老年斑”。此时主人也不必过度紧张，属于正常现象。

2、细菌、真菌感染引起的皮肤病

如果狗狗感染真菌、细菌等皮肤病，也可能会在皮肤上面形成黑色的斑点，通常伴随皮屑、脱毛、癣斑、脓液等症状。建议及时将狗狗带去宠物医院，进行皮肤全身的化验和检查，找到真正的病因后，在展开针对性的治疗。

3、寄生虫感染

如果狗狗太久没做体外驱虫，也可能是因为寄生虫粪便导致的黑点，一般会附着在皮肤上，比如跳蚤。可以用湿纸巾摸一下黑点，看看是否有血迹，如果有的话，就需要尽快给狗狗做体外驱虫。

4、长时间没有洗澡清洁

狗狗休息的时候喜欢肚皮朝下趴着，当肚皮接触脏东西的时候不及时清理，就容易有黑色脏东西附着。可以用湿纸巾擦一下斑点，如果是能够擦掉的，则可能是污物引起的，给狗狗洗澡清洁干净即可。

5、基因遗传

部分狗狗是天生皮肤上就有黑色的斑点，比如斑点狗，如果没有明显的异常就不用过多理会。
