I was going to leave replies to a couple comments on the Good Boy Zeekie post then decided to make a complete post on the subject.
It was October 2016 and I was preparing to leave for the desert for the winter. I felt it would be Sinbad’s last adventure with me. One evening he was sitting next to me in my chair as he always did while I read. He jumped down, went over under my desk and laid down. He never went over there. I went to lay next to him. Two hours later he passed away peacefully.
