狼和非洲野犬不是一个属的,是2条进化支系狼本身就是Canis下的一个物种,这个属内的动物叫狼、犬的都无所谓
的确有人把非洲野犬和亚洲的豺狗划分成了一大类.犬科动物中,除了犬属的狼之外,唯有这类是成群捕猎的顶级肉食动物.美洲的薮犬也成群捕猎,不过体型比较小,达不到这样的顶级地位,而且过去也有人把薮犬和非洲野犬、豺狗划分成一大类的.基本上可以说狼是和他们平行演化的一个特例.

非洲野狗与狼同科但不同属,伪犬科没听说过,家狗与非洲野狗只是有一字相同,在物种上距离较远.
家狗之前分类学中列为单独一种,但随着分子生物学中DNA分析技术的发展,已有人把家狗不再列为单独物种,而是列为狼的亚种.
随着生化考古学的发展(化石DNA提取和分析),发现很多物种有一个起始点存在,而非全球散在并存.所以非洲无狼应从另一个角度去进行考虑.
非洲野狗
African-Wild-Dog - 非洲野狗
学名:Lycaon pictus
种类:哺乳动物
群体名称:Pack
食谱:肉食
平均寿命:11 年
尺寸:75-110 cm
体重:18-36 kg
受保护状况:濒危
The African wild dog,also called Cape hunting dog or painted dog,typically roams the open plains and sparse woodlands of sub-Saharan Africa.
非洲野狗又称猎狗或彩色狗,通常出没在撒哈拉以南非洲的开阔平原或稀疏林地.
These long-legged canines have only four toes per foot,unlike other dogs,which have five toes on their forefeet.The dog's Latin name means "painted wolf," referring to the animal's irregular,mottled coat,which features patches of red,black,brown,white,and yellow fur.Each animal has its own unique coat pattern,and all have big,rounded ears.
这些长腿獠牙的家伙每只脚上只有4个脚趾,而其它的狗有5个.这种狗的拉丁名字叫"彩色狼",这源于它那缀满红,黑,棕,白,黄颜色的皮肤.每只狗都有独特的外皮和大而圆的耳朵.
African wild dogs live in packs that are usually dominated by a monogamous breeding pair.The female has a litter of 2 to 20 pups,which are cared for by the entire pack.These dogs are very social,and packs have been known to share food and to assist weak or ill members.Social interactions are common,and the dogs communicate by touch,actions,and vocalizations.
非洲野狗过着群居生活(Pack),通常由一对夫妻控制.雌狗生育2-20只细仔,由整个群体来照看.野狗非常社会化,群体内会分享食物并看护体弱多病的成员.社会性的互动很普遍,它们通过接触,打斗和叫声来交流.
African wild dogs hunt in formidable,cooperative packs of 6 to 20 (or more) animals.Larger packs were more common before the dogs became endangered.Packs hunt antelopes and will also tackle much larger prey,such as wildebeests,particularly if their quarry is ill or injured.The dogs supplement their diet with rodents and birds.As human settlements expand,the dogs have sometimes developed a taste for livestock,though significant damage is rare.Unfortunately,they are often hunted and killed by farmers who fear for their domestic animals.
非洲野狗以可怕的团队形式(6到20多只)来捕猎.在这种狗濒临灭绝前,更宏大的群体也很常见.野狗捕食羚羊和更大的猎物,如角马,特别是在猎物生病或受伤的情形下.狗的食物还包括啮齿类动物和鸟.随着人类的扩张,野狗有时也袭击家畜,但罕有严重的袭击.不幸得是,它们经常被担心家畜受伤的农民所猎杀.
African hunting dogs are endangered.They are faced with shrinking room to roam in their African home.They are also quite susceptible to diseases spread by domestic animals.
非洲野狗已濒临灭绝.在非洲家乡的活动空间越来越小.它也非常容易受到家畜传染病的侵袭.
最终答案,关系较远不能杂交
