My grandpas dog Sue passed away last night while I was sleeping

I know she's in heaven now. My grandpa left her to me after he passed and I haven taken care of her since. My mom woke me up at around 6:00 AM and she hugged me and told me what happened. She was old but we don't know how old because she showed up as a stray at my grandpas house around 15+ years ago according to him and she was already full grown. We never found out what breed she was but she gave me and my family so many memories. I enjoyed seeing her make my grandpa so happy and it made it happy. May you rest in peace Sue. I love you.
