He was acting normal earlier this morning. He ate his food, and laid down by my feet under the desk like he always has. I combed and petted him like I always do in the mornings. I got up to check the mail and put the laundry in the machine, When I got back, I petted him again, he didn't respond. His eyes were open, but he wasn't breathing and I couldn't feel a heartbeat. I'm guessing he had a sudden heart attack. If so, hopefully he didn't suffer. :-(
Andrew helped me bury him in the back yard.
