So... try Pepto Bismol to settle his stomach and watch for signs of deterioration or improvement???
My son, as I write, has gotten him to eat a bit of his regular food and to chew on an ice cube, which is more than he has done in two days. He has not vomited since Friday, but he also has not urniated since last evening (over 16 hours ago).
He is normally a very peppy dog and the past three days has been very tired, laying around, not playful... I guess that worries us a lot, too.
I plan to atke him to his regular vet tomorrow, unless you recommend that I get him into today with soemone sooner... I don't know any emergency vet info as I ahve never needed one before.
