We have two kiko does and two nigerian dwarf does. One of the kikos is pregnant and one of the nigies (hopefully) is as well. The first doe we got was a 4(or so) mo. old Kiko, and our male Great Pyrennees did not leave her side for the longest time. But when I got the two Nigies, he started to chase them. He has since started to chase the heavily preg. kiko doe. Why is he doing that and how do I get him to stop?
