Domestic dogs play many vital roles in human lives; however, relatively little is known about how they perceive the world visually. Given dogs’ recent popularity as a subject in cognitive and behavioural studies, it is important to understand how they visually interpret the world around them. One way to evaluate perception is to assess illusion susceptibility; specifically, how visual information is processed, interpreted and modified post‐retinally. While illusion susceptibility has been used across a variety of species to comparatively assess the similarities and differences in visual processing and perception, this relatively novel methodological approach has only recently been adapted to evaluate perception in domestic dogs. Here, we present a comprehensive overview of the findings from studies that have evaluated domestic dogs’ illusion susceptibility, highlighting the relevance of these results for those studying illusion susceptibility in animals as well as canine behaviour and cognition. More specifically, the ultimate goal of this review is to answer the questions: (a) Are dogs susceptible to visual illusions? (b) If so, are they susceptible to illusions in a way that parallels humans and/or other animals? (c) Are findings, within dogs, consistent and if not, how might these be interpreted and explained?

家犬的幻觉敏感性

家犬在人类生活中起着至关重要的作用。然而，关于他们如何从视觉上看待世界的知之甚少。鉴于狗最近在认知和行为研究中成为一门学科，因此了解它们如何从视觉上解释其周围的世界非常重要。评估知觉的一种方法是评估幻觉的敏感性。特别是视网膜后如何处理，解释和修改视觉信息。尽管幻觉敏感性已被用于各种物种，以比较地评估视觉处理和知觉的相似性和差异，但是这种相对新颖的方法学方法直到最近才被用于评估家犬的知觉。这里，我们对评估家犬幻觉敏感性的研究结果进行了全面概述，强调了这些结果与研究动物幻觉敏感性以及犬的行为和认知的研究结果的相关性。更具体地说，本次审查的最终目的是回答以下问题：（a）狗是否容易出现视觉错觉？（b）如果是这样，它们是否容易以与人类和/或其他动物类似的方式产生幻觉？（c）在狗内的发现是否一致，如果不一致，如何解释和解释？（a）狗容易视错觉吗？（b）如果是这样，它们是否容易以与人类和/或其他动物相似的方式产生幻觉？（c）在狗内的发现是否一致，如果不一致，如何解释和解释？（a）狗容易视错觉吗？（b）如果是这样，它们是否容易以与人类和/或其他动物类似的方式产生幻觉？（c）在狗内的发现是否一致，如果不一致，如何解释和解释？
