Included in this month’s issue of AKC Family Dog magazine was a little snippet of information about breeding that many would find surprising… Puppies in a litter can have different fathers!
From the AKC familydog Magazine “Ask Dr. Kevin [Fitzgerald, DVM]” article:
“Females can breed with multiple males while in heat and can ovulate up to 20 ova. This, there can be numerous eggs available for fertilization. As a result, multiple fathers can be responsible in siring a litter. Furthermore, successful breedeings can be several days apart, which enables sibilngs in the same litter to be from different fathers.”
So, even when dogs are littermates, they could be only half siblings if the litter is multi-sired. This occurance also happens in cats and even humans, with fraternal twins having different fathers!
