==对自然生態的影响==
狗是外来入侵种之一。由于人类饲养的家犬有稳定的食物来源，家犬的竞争力增强，对野生动物会造成更多的干扰<ref>{{cite journal |last1=Young |first1=Julie K. |last2=Olson |first2=Kirk A. |last3=Reading |first3=Richard P. |last4=Amgalanbaatar |first4=Sukh |last5=Berger |first5=Joel |title=Is Wildlife Going to the Dogs?

家犬还可能向野生动物传播疾病，如[[狂犬病]]和[[犬瘟热病毒]]的传播<ref>{{cite journal |last1=Gehrt |first1=Stanley D. |last2=Wilson |first2=Evan C. |last3=Brown |first3=Justin L. |last4=Anchor |first4=Chris |title=Population Ecology of Free-Roaming Cats and Interference Competition by Coyotes in Urban Parks |journal=PLoS ONE |date=2013-09-13 |volume=8 |issue=9 |pages=e75718 |doi=10.1371/journal.pone.0075718}}</ref>。一个典型的例子是2014年陕西省林业科学院秦岭大熊猫繁育研究中心圈养的[[大熊猫]]感染[[犬瘟热]]死亡<ref>{{Cite thesis |degree=博士 |chapter= |title=大熊猫犬瘟热流行病学调查与实验免疫研究 |url=http://cdmd.cnki.com.cn/Article/CDMD-10193-1017842502.htm |author=冯娜 |last= |first= |year=2017 |publisher=吉林农业大学 |accessdate= |docket= |oclc= }}{{Dead link}}</ref>。
