Yeah back in the original tracker okaki thread everyone mate'd up there tracker dogs... There was even a separate thread for it with lists of available trackers and one's who'd been mated up. Even though they could not have children it was still pretty fun writing them together.
Also Nex had a thread back then where she would actually make puppies for the people. Two pups per litter (one for each owner) and that was all both the bitch and the stud could have in there entire lives even if they were paired up with another tracker. There are 4 sets of two pups in all in that breeding thread.
