Oh Cathy I missed all this; have been abroad for work for a few days. I am so glad he is getting back to normal. How scary! Jaspar too lifts one leg BTW when he wants something or is interested in something. Once or twice Jaspar has had bad diarrhea and he makes it clear how uncomfortable he is but he's not had anything that sounded as bad as this and I'd have not hestitated to do what you did; get him to the vets; you just never know. I've given a bit of pepto bismol and that has always helped. I'd guess he might have eaten something that really upset him; maybe something along the beach. Or something with a bug in it.
