Domestic dogs can negatively impact natural systems, and understanding these dynamics is essential to mitigate their impact. We report two cases of attacks of domestic dogs on native mammals in a fragmented landscape of the Atlantic Forest, southern Brazil. Our records occurred in a region of high priority for the conservation of this biome. We observed two attacks, one on a Common Long‐Nosed Armadillo Dasypus novemcinctus and another on a Southern Brown Howler Monkey Alouatta guariba clamitans. Our records highlight additional threats to the wild and native fauna reinforcing the importance of accounting for the presence of domestic fauna when delineating conservation strategies in highly fragmented environments.

家犬对零散的大西洋森林中常见的长鼻犰狳Dasypus novemcinctus和南棕How叫猴Alouatta guariba的袭击及其对生物多样性保护高度重视的区域的影响

家犬可能会对自然系统产生负面影响，因此了解这些动态对减轻其影响至关重要。我们报告了在巴西南部大西洋森林的零散景观中发生的两只家养狗袭击本土哺乳动物的案例。我们的记录发生在该生物群落保护的高度优先区域。我们观察到了两次袭击，一次袭击了一只常见的长鼻犰狳Dasypus novemcinctus，另一次袭击了一只南部的棕色How叫猴Alouatta guariba clamitans。我们的记录突出显示了对野生和本地动物群的其他威胁，这在描述高度分散的环境中的保护策略时，强调了考虑家庭动物群存在的重要性。
