Sad little moment here

So... after 13 years, 2 goodbyes and 1 visit.. my grandma just told me dog died.

He came to us when we moved into a new house, thinking we could start good, with a nice place and our family together and our baby dog. Sadly, when a few years later we moved to a new place and he couldn't come. I remember that day well. Me and my grandma were the only ones there when his new owners came to pick him up. I cried and cried, watched him get in the car and go. I knew he would be taken care off, he would be happy but I couldn't help to feel we betrayed him by leaving him. Given he lived far, I couldn't go and visit him and the first time I saw him were last year. I can't believe he's gone now. I've been crying ever since I found out. I love him so much and I'm gonna always miss him.
