They did not to the blood work for liver kidneys yet. I will find out more tomorrow when I speak with the vet. I have lots of questions. Also about the tongue thing the last I heard was to keep an eye out and I think the extra stuff was removed. Not sure if he injured it and it was scare tissue??Great he is going home soon. Did they ever determine what was under his tongue, not sure if you posted about that and maybe I missed it. Have they done the blood work for liver and kidneys?
