How can I get my dog back to normal?

I have a year-old corgi/scottie mix. She has become obsessed with catching and killing small rodents. When I try to get her to come in the house, she growls and lunges at me. She hasn’t bit me, but makes it very clear that she isn’t finished with her hunting yet.

Does anyone else have experience with this? My favorite dog is turning into a monster. I can take her out on a leash or tie her to a lead, but I want to change her behavior.
