[HERBS]

Have any of you had your yorkie have a false pregnancy after their heat cycle? Every single heat cycle my oldest girl (almost 3 yrs) has been through she has had a false pregnancy follow. I have not asked the vet about this. She is going through one right now. This one seems to be worse than the previous ones. Is this something I should worry about? Should I schedule a vet check up because of it? She is my pet and I do not breed so she has never had babies. I am planning on having her fixed before her next cycle but very curious if other female yorkie mommies have experienced this and if maybe you can tell me why. Is it something I should worry about? I KNOW she is not pregnant, that is not even in question. Just a general health question...
