Apparently the answer to a previous post is that blood in the diarrhea is the time to take him to the vet.  Yesterday Bleys added that little gem to things, so this morning I called and the vet squeezed us in at 9:00.  After some testing they think its a bacterial infection possibly caused by his recent habit of licking dirt.  So the vet recommended a supplement called Dogzymes, as a deficiency might explain the dirt licking in the first place.  He’s staying there overnight and I’m researching the Dogzymes.  I wish I knew more and could feel more like I was making an informed decision.  Anyone have any knowledge here?
