Abstract Small Animal Reproduction is a rather recent topic in the field of Animal Reproduction. Although some continuing educational societies aim to improve the level of general knowledge, published scientific facts are still limited, and there are many hypotheses or affirmations that remain unverified or even sometimes dogmatic or empirical. Through examples, this article reviews the main causes that may sometimes challenge a veterinary practitioner faced with a dog or a cat presenting reproductive problems. It could be difficult to orientate the diagnosis or the therapeutic approach, not knowing if what is found in the literature is a scientific proof or just an unverified affirmation. This problem may result from the fact that there are still physiological processes that remain unclear, but also that some common beliefs are based on old studies that have not been repeated or verifiedIn addition, to make it more challenging to seek for the information, there are unverifiedaffirmations,unclear nomenclature, clinical conditions which have not been standardized in the literature, clinical conditions mostly described through case reports, lack of studies on specific topics, areas of small animal reproduction that have been neglected by researchers, contradictory data or even studies that lack objectivity. The growing interest for research in Small Animal Reproduction will probably reduce the gap between unverified beliefs and scientific facts.

小动物繁殖：科学事实与教条或未经证实的信仰。

摘要 小动物繁殖是动物繁殖领域的一个较新的课题。尽管一些继续教育协会的目标是提高常识水平，但已发表的科学事实仍然有限，并且有许多假设或肯定尚未得到证实，有时甚至是教条或经验主义的。通过示例，本文回顾了兽医从业者面对出现生殖问题的狗或猫有时可能会遇到挑战的主要原因。可能很难确定诊断或治疗方法，不知道文献中的内容是科学证据还是未经证实的肯定。这个问题可能是因为还有一些生理过程尚不清楚，但也有一些共同的信念是基于未经重复或验证的旧研究此外，为了使寻找信息更具挑战性，还有未经证实的肯定、不明确的命名、未在文献中标准化的临床状况、临床情况主要通过案例报告描述，缺乏对特定主题的研究，研究人员忽视的小动物繁殖领域，相互矛盾的数据甚至缺乏客观性的研究。对小动物繁殖研究日益增长的兴趣可能会缩小未经证实的信念与科学事实之间的差距。文献中没有标准化的临床情况，临床情况多通过病例报告描述，缺乏特定主题的研究，被研究人员忽视的小动物繁殖领域，相互矛盾的数据甚至缺乏客观性的研究。对小动物繁殖研究日益增长的兴趣可能会缩小未经证实的信念与科学事实之间的差距。文献中没有标准化的临床情况，临床情况多通过病例报告描述，缺乏特定主题的研究，被研究人员忽视的小动物繁殖领域，相互矛盾的数据甚至缺乏客观性的研究。对小动物繁殖研究日益增长的兴趣可能会缩小未经证实的信念与科学事实之间的差距。
