This report describes multiple congenital malformations found in three dog litters delivered by emergency caesarean section. In all of the litters, some puppies were born alive but were euthanized because of the seriousness of their malformations and low probability of survival. In two litters, gastroschisis was associated with amelia of the right anterior limb. Other malformations such as anencephaly were also found in three puppies among the different litters. This report describes the morphological findings of the affected puppies, discusses the most appropriate terminologies for each case and highlights the importance of an epidemiological survey to identify potential factors associated with the cases.

该报告描述了在紧急剖腹产的三只狗窝中发现的多种先天畸形。在所有的幼仔中，有些幼犬还活着但由于其畸形的严重性和低存活率而被安乐死。在两个垫料中，胃痉挛与右前肢的肌无力有关。在不同垫料中的三只幼犬中也发现了其他畸形，例如无脑畸形。该报告描述了受影响幼犬的形态学发现，讨论了每种病例的最合适术语，并强调了进行流行病学调查以识别与病例相关的潜在因素的重要性。
