I had that happen, too. Dog was in the hospital for a procedure. They called to tell me it went well, and he was waking up. Got another call a short time later. His temp was over 106, and they needed to cool him down. They wanted permission to do what they needed to do to get him stable. They didn’t want to have to take the time to call several times if the first step wasn’t working. They said it was something to be aware of in case he ever had to be put under in the future.
