Mercedez,
I am so sorry for everything you and Opa went through. I hope that he will be okay and I am sending healing thoughts to him and to you. In my opinion, you made the right decision with Beez. Unfortunately, he was not safe around humans or other animals. I have had to make that decision myself with aggressive dogs before and I know it was painful and I know it isn't easy, but I feel you made the right decision. I am thinking of you and Opa.
