Hi, thanks for using Petco Pet Education Center, formerly Petcoach! If this is a sudden behavioral change I would have her examined. She could be painful or not feel well and she is acting out because of that. It is better for her health to be spayed, she is at risk for an infected uterus which is an expensive surgical emergency. Hormones can affect temperament, so it MAY help but it might not be the solution. If her exam and blood work are normal, you can have her spayed then consider training and medications to control her aggression. I hope this helps and I wish you and Bella the very best!
