Sending prayers and healing thoughts for Opa, I'm so glad to hear that he perked up when you brought him to the vets. And no judging on my part. You just focus all of you positive energy on Opa, he needs you , and we're here for you!
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.
I have no words just love for Opa and you. I will pray he comes, out of this ok... Mercedez no judging, you did what you thought was ok in your heart.. Hug's to you and Opa please let us know how he is doing.. He is one strong bird to go through all that and such strong will..
