OMG!!! I am so sorry for you, your Aunt and Uncle. I never had that happen. But we have hawks in our neighborhood and I saw one get a blue jay, and when I opened the door in my front yard to get him to fly off, he took the bird with him up into the air. I have seen a hawk hanging around here lately. I don't have dogs of my own, just an inside cat. I do watch my 2 daughters dogs from time to time. I have them this week. I go out with them and watch them like a hawk. I would be devastated. So sorry, hugs and prayers to you all.
