As I mentioned in my last update on Tia, she was very nervous and worked up yesterday when I went to visit. In fact, while Dr. Hannah was at our farm working, she received several calls about Tia from her farm help at NWESC. They thought she was upset because the other horses were out so brought another horse in across from her that she could see. That seemed to settle her for a little while but then she got worked up again, for no apparent reason. She was excited when I was there, pacing and calling, and they had taken her blanket off earlier because she had worked herself up to a sweat. Dr. Hannah called me last night to say that she was very concerned about Tia whose behavior continued to escalate throughout the evening even as other horses were brought into their stalls. She finally gave her some Ace which did settle her down. However, she is very concerned about the anxiety for no apparent reason and took bloodwork on her last night. One possible cause for unexplained anxiety is liver failure, and another is a brain tumor (such as Cushings). Neither are very good possibilities, so I am anxiously awaiting an update this morning as to whether or not Tia was calm this morning after the Ace wore off or if she was again agitated, and also waiting for the results of the bloodwork. Hopefully I will have a more positive update later today.
