Plain-English summary
A study looked at the reasons why some dogs need cesarean sections (C-sections) during birth. It found that about 22% of litters were delivered by C-section, with many being emergency procedures due to complications like dystocia (difficult birth). Factors such as the age of the mother and the size of the litter played a role, with older first-time mothers and very small or very large litters being more likely to require surgery. The study also noted that certain breeds, like the Norwich Terrier, had a much higher rate of C-sections compared to others. Understanding these factors can help dog owners and vets make better decisions about when a C-section might be necessary.

Abstract
Dystocia in the canine species is a common problem, and elective cesarean sections (C-sections) have become more frequent in breeds that are at risk. The aim of this study was to evaluate the incidence of C-section and contributing factors and to compare data on elective and emergency C-sections (e.g., regarding stillbirth). Using a questionnaire, a total of 423 bitches of 80 breeds and their 899 litters were included. The mean number of litters per bitch was 2.1 ± 1.1 litters. The overall rate of stillbirth was 6.7%. Of all litters, 194 were bornC-sections (21.6%), of which 35 were declared as elective and 159 as emergency due to dystocia. Significantly more C-sections were performed in either small litters (1-2 pups) or large litters (>12 pups) (p < 0.001). Bitches that have had prior C-sections had a 4-fold increase in the risk of successive C-sections (RR = 4.54 (95%CI 2.56-7.70;< 0.001). Furthermore, primiparous bitches of advanced age had a significantly higher incidence of emergency C-sections (= 0.004). Stillbirth was significantly higher in emergency C-sections compared with that in elective C-sections (= 0.003). Also, timing of intervention had a significant impact on stillbirth in emergency C-sections (= 0.025). Within a breed-specific evaluation, significant differences were observed between breeds regarding incidence of C-section and stillbirth. Lesser-known breeds were represented in the population, and the results showed that the Norwich Terrier had the highest (51.6%) and the Gordon Setter had the lowest (4.8%) incidence of C-section (< 0.001). The inclusion and evaluation of lesser-known breeds regarding incidence of C-section is of importance as it shows that certain breeds without phenotypical traits such as brachycephaly may also have an increased incidence of emergency C-section and stillbirth. We further conclude that more importance may be given to the age at first parturition concerning the occurrence of dystocia and the decision making regarding possible elective C-sections.
