So I have a female that finished her heat cycle in early July , I have male that is 6 years old...well Dallas during her heat cycle would try and hump her and then once her cycle was over he would leave her alone and if get annoyed when she came around him, but again this week and last week we are noticing he is trying to hump her again, she is getting so annoyed w/ him that she now growls at him when he just looks at her....why would he all of a sudden be on her again like this...I mean he acts like he has no brains...She can't be in heat again right ? There is no blood ..her vuvla is there of course but I am not sure if it's swollen , I have noticed she eats more and is super lovey dovey .....what are your thoughts my fellow Yorkie Lovers? I thought maybe she was prego but her belly is normal size and by now she would be showing ...
