Hello to you, Missy and Beau and a warm welcome to Yorkie Talk.
Regarding the fighting, it sounds like Missy is just being a "protective Mama" but cannot say for sure. Does she feel ok, not been sick or anything to make her cranky?
I am not a breeder so cannot give you any concrete advise but still wanna welcome you to the best Yorkie forum around!
Id love to see pics of your fur babies if you'd like to share too!
