Jasper seems a bit off colour. He's eating, drinking, toileting normally, but seems quite lethargic. He keeps retreating to quiet corners and sleeping instead of bouncing about causing mayhem. And when I fed the DC, he laid on the back step looking sad instead of trying to steal their sausages. Every so often, he mooches about with a toy, but he isn't himself. I thought he was limping slightly this morning, but haven't seen him do it since. He was fine on his walks, but they were both on lead so couldn't really judge enthusiasm. I can't see anything obvious, no vomiting, whining, scratching etc. If he shows no signs of returning to his bouncy self in the morning, I think we'll be off to the vet
