Caesarean Birth Frequency in the UK
Analysis of Frequency of Caesarean Births in Clumber Spaniel litters born from 2014 to 2018
In 2010 Evans and Adams* published a paper which suggested that Clumber Spaniels were among the ten breeds with the highest rates of caesarean births. Their data was taken from the 2004 KC/BSAVA Scientific Committee Purebred Dog Health Survey based on 170 breeds. There were 44 Clumbers in the survey with 62 litters. Of these litters 28 were born by caesarean section giving a rate of 45.2% which placed Clumbers in 8thhighest position. The authors suggested that the high rates provided evidence for monitoring the number of caesareans in some breeds.
The KC currently requires breeders registering a litter to declare whether the dam had had an emergency caesar (C-EM) or an elective caesar (C-EL). Furthermore the KC will not register a litter if the dam has already had two litters delivered by caesarean section without permission being given before the mating takes place.
Information on caesarean births is included in the KC Breed Record Supplement in the Litter Registration Section. This information has been collated for Clumber Spaniel litters born in the years 2014 to 2018.

This gives an average rate over this five year period of 14.4%. The red line in the graph below is the trend line which is going down very slightly over this period.
