I woke up at 4 am to his crying and rushed him into the vet. It was gastric torsion and it came out of no where, he was sound asleep in the kitchen, the last time I was up. Due to his age and underlying health issues and in discussion with the vet, we elected not to do the surgery. He was in agony and I couldn't bear to let it continue. I am so sorry Phil.
I think you did the right thing Carol. He had a great month with you, not left in a shelter , all alone. He was a lucky boy to share your house and your bed.
