Roscoe was *sound* asleep earlier, not even twitching at the sound of his name or the crank of a can opener. I put a chunk of roast pork right in front of his nose because I had given Bella one, and I have to be scrupulously fair even if the other dog has no idea what's going on.
No response, still snoozing. But then several seconds later, his feet start twitching like he's having a dream. Then his whole body starts twitching. Then his nose starts sniffing. Still sound asleep as far as I can see. All of a sudden, he leaps up, gulps the pork bit down, looks around like he's not sure where he is, sees me and comes over for petting.
I think he had a dream that he was chasing a pig.
