Ray was fine yesterday although I noticed late yesterday afternoon when he got up after a nap he seemed stiff. But then we went for a walk around the block, he ate dinner with his usual gusto, and got up to sniff what we were having for dinner. Last night Gregg took him out to pee before putting him to bed. All was normal.
This morning Ray was shivering and wouldn't stand. We covered him with a blanket and carried him out to the car on his cushion.
The vet will call us later with info.
