First I am so glad you are both ok. But I have to agree with some others. Maybe you should start Lucy out slow just meeting with a few other dogs at a time and get her trained not to snap. We had a few small issues with Lolo and our neighbors boxer who thank goodness is as gentle as a lamb, but I would pick Lolo up tell her no and put her face to face with Bell and make her play nice. It only took a couple times and now they are great pals.
