My first yorkie came into heat when she was 10 months old.. My two yorkie girls now will be 7 months on Thursday and the one I'm thinking came into heat (her hoo hoo is bigger than it was a few months ago and her nipples are noticeable - but then again maybe she hasn't!) whereas her sisters hoo hoo is quite small and I know she hasn't gone into heat yet.. Her nipples are also still flat with her belly.. |
