I'm so glad that you finally heard back from the vet and that Barney will be put on the proper antibiotics. I think everyone should take this as a lesson and speak to their vet regarding vaccinating. It's amazing that you are so attune to Barney that you would pick up on the slightest differences in his behaviors.
