$400 later (although some of this was for her regularly scheduled exam, fecal, and worm pills), she got Cerenia and Famotidine injections and tablets and a blood test, results TBD. She is on Canine ID and the Cerinia tablets for a few days. Hopefully the blood test will come back negative and this is just a passing episode. One additional thing we are worried about is that she was chewing on a new foot stool I bought and ate some wood and must have digested some of the finish. This thing was made in the far east, so that is always a concern. Anyway, she at least is displaying no symptoms at this point.
