My neighbor's wonderful companion animal died last night suddenly. He was so very spry and healthy. How can that happen?

He was 11 years old, very lean muscle mass, very active, and they walked him every day, and I had walked him myself many times. I can't imagine Thanksgiving in their home now with Obie gone, as he would get up on he couch with me and lay on my lap when I petted him.

We have all, at some time lost a wonderful companion and it leaves a large hole in my heart to have him gone.

The SYSTEM put this question under "sexuality' for some idiotic reason and I changed it to other.
