What do you mean she is attacking him? Is it over food, toys, attention????? What does Bentley do when she does this? Does he back down? Is there blood?
My three will fight sometimes but it's always over in a flash. It usually happens when someone is walking past the house and they are all pushing to get the best view of the passerby.
She must being showing signs before she goes after him. Are you watching for her trigger? When you see the signs do you intervene before she goes after him? After she goes attack him what are you doing with her? Do you separate her into a different room or crate her?
