in my opinion, saying "accident" or "unplanned pregnancy" is only legitimate when, as stated earlier, two chins mate as a result of escape or missexing.
a few posts ask why the pair wasnt separated, i ask "why were they even together if breeding wasnt intended?"
i, like many others, didnt know who this thread was aimed at. and for all we know, there are NUMEROUS members on this thread to whom this thread can be applied.
i believe that the OP intended this thread to be a discussion on how "accidents" dont just happen. they can be preventable, except in cases where it is out of our control (escape mating). im glad this thread was posted so that people, who are pet owners, know the consequences of pairing chins.
as laurie stated, if you put two naked humans together, they CAN breed. if you put two chins together, they CAN breed. thats not an accident on the chins part. its an accident on the owners part. so as a note to all chin owners: IF YOU DONT INTEND TO BREED, DONT PUT A PAIR TOGETHER.
