Demi Lovato Opens Up About 'Tragic' Death of Her Dog

"He was taken from us way too soon," she wrote.

She continued, "We have incredible people around us and so much love and support which is holding us up in this time of need. Buddy was loved by so many people and as small as he was, he made a huge impact in our lives."

In the post from Tuesday, she didn't specify what the accident was.

"He truly was human in a way and we were so blessed to have him in our lives. We ask you that you please respect our privacy while we take this time to grieve and remember the magical moments we spent with our little angel. We will never forget our baby boy Buddy and his gentle loving spirit will live on in our hearts forever. RIP my tiniest little nightingale, Buddy..." she continued.
