摘要: Despite the long history of purebred dogs and large number existing breeds, few studies canine litter size based upon a breeds exist. Previous are either old or include only one selected breeds. The aim this large-scale retrospective study was to estimate mean in population describe some factors that might influence size. A total 10,810 litters 224 registered Norwegian Kennel Club from 2006 2007 were included study. overall at birth 5.4 (± 0.025). generalized linear mixed model with random intercept for breed revealed significantly influenced by breed, method mating age bitch. significant interaction between detected, expected puppies born decreased more older bitches Mean increased size, 3.5 0.04) miniature 7.1 0.13) giant No effect on found season parity detail information unique. In conclusion, bitch when controlling as strongest determinant.
