Well, of course, I know where puppies come from, but I didn't know it involved the same menstrual process as humans! Do they call it that? Is it a dogstrual process?? YUCK.
I told my BF last night this fascinating tidbit of information. He was in the other room, so I couldn't see his face, but his reply was, 'Uh, I could have gone the rest of my life without knowing that.' *lol* I felt better that he didn't know that, either, and he's had lots of dogs.
