did you know?

Q: Is it possible for one litter to contain puppies from 2 different male dogs?

A: Yes. Although each ovule can only be fertilized once, in each heat stage somewhere between 2 and 20 ovules mature, so a female dog may become impregnated from a few different male dogs if she has humped more than one during that time.
