Please Help

I’m unsure if this is the correct place to post this. If I should do this elsewhere, please let me know. My grandpa took his dog to the Humane Society last Saturday and then went home and took his life. I’m doing everything I can to locate Clarabelle, his pup. She is an older Shih Tzu. If you have any information, Please pm me. I dont have anything to offer, but it would be greatly appreciated. I have called the Humane Society and left a message, just want to check all the boxes.
