Random midnight thought - are puppies in the same litter technically fraternal twins? 🐕

Turns out, yes and no.

[#]Dogs are superfecund, that is, a single mother can have multiple eggs fertilized by different fathers.

So its possible that a litter might have a few half-siblings and/or a few fraternal twins. If there's only 1 father? All fraternal twins.

Thanks for joining me on this random research rabbit hole.
