First, welcome to YT! I'm from LA too, Many. I see you must be around Pineville?

I had a similar problem, but with 2 of my males. One yorkie and one a little mixed rescue. Got them all fixed and things did get better. We have since rehomed the rescue, so things are good now. I have 4 males and 1 female, all fixed, all pets. I do agree with the other poster, sending Millie to live with your daughter might be your best solution. Again, welcome!
