Friday November 2nd - vet check then ultrasound and anemia

well today was a roller coaster.  had a vet check up.  Went in and his weight has remained stable. yay!  and his lymph nodes have all shrunk and are the best they have been. yay!  They took blood to check to see where he was with the anemia.  We left happy - Ernie with his ball in mouth (he takes his squeaky tennis ball with him everywhere now).  I dropped him off and went back to work.  Got a call from the vet at work.  His blood work shows an even lower PCV.  Meaning his bone marrow isn't producing new red cells, or he is bleeding internally, or who knows.  It was sooo upsetting to hear. My stomach rolled over and I started crying. I said to Dr. Beaver, wow... I am worried. And she said, yeah so am I. So I told work I had to leave and of course couldn't even get it out without losing it. Sometimes its really hard to hold it together. So back to the vets for an ultrasound. This was not the news I was expecting after our 'wins' earlier.  Went home and grabbed Ernie (and the ball in mouth) and went back to the vets.  I waited anxiously for the ultrasound and results.  It seemed like it took hours. They had the Discovery channel on the TV and it was a show about infestations. Rats, cockroaches, bats. Totally freaky and disgusting. But it was so freaky and disgusting that it created a welcome distraction and created conversation between me and the women the work the front desk area.  Finally met w/ the vet and the good news was all looked good inside.  And he didn't stress too much during the procedure.  I asked them to please not put him on his back if they didn't have to, because he doesn't like being on his back and had to do that with his previous ultrasound.  so they did it on his side. And of course prior to the procedure Dr. Beaver had said he is shows any signs that he is really stressing we will pull the plug. They are so great at this place. And have always taken great care to do whatever they can to keep Ernie at east.  Anyways. All looked good...  no tumors, or bleeding or fluid.  But .. now what?  What is causing this anemia??  There is no good answer right now.  So he got a vitamin B shot and a recommendation for iron supplements, and we go back on Tuesday.
