Abstract The gray wolf and the domestic dog are closely related species that can interbreed and produce fertile offspring. In settings where unrestrained dogs are present in the wild, hybridization can happen naturally. However, the behavior of the resulting hybrids and their ecological impact is largely understudied. In September–November 2018, a putative gray wolf was repeatedly camera-trapped in a group of 10 presumably feral dogs in a remote mountainous area (the Osogovo Mountain) along the border between Bulgaria and North Macedonia. The most feasible explanation for this individual’s atypical behavior is that it is of hybrid origin (assumption based on phenotype). To the best of our knowledge, this is the first documented observation of such a kind. A discussion of its recruitment and position in the group is presented, setting the basis for further investigation of the complex interaction between wolves, dogs and hybrids in the wild.

过着狗的生活：野狗群中的假定灰狼

摘要 灰狼与家犬是亲缘关系密切的物种，可以杂交产生可育后代。在野外存在不受约束的狗的环境中，杂交可以自然发生。然而，由此产生的杂交种的行为及其生态影响在很大程度上没有得到充分研究。2018 年 9 月至 11 月，在保加利亚和北马其顿边境的一个偏远山区（奥索戈沃山），一只假定的灰狼反复被相机困在 10 只可能是野狗的群体中。对这个人的非典型行为最可行的解释是它是杂种起源（基于表型的假设）。据我们所知，这是首次记录在案的此类观察。介绍了其在集团中的招聘和职位的讨论，
