It is just past 11:00am now and my Wagster won't eat and is just curled up in his crate. We did take him out for a short time and got him to go outside and pee, but then he just sat down in the garage and didn't want to do anything. He is obviously still feeling puny and I think I'll let this go on for one more night. If he's not improved by tomorrow morning, another trip to the vet is definitely in order.
There are not many things more pathetic than the face of a dog who doesn't feel good!
