Okay, I will call the vet tomorrow. I hate bugging them when I know how busy they are but I guess in this instance I really need to ask them. Ryle, I was kind of afraid that would be the answer. Probably not a good idea to go. I will also ask the B/O what the specific result of the culture was. Not sure he knows, just said it was a virus the vet told him. But I can investigate further. Mostly the question was whether there was any treatment like antibiotics and we got that answered with the negative. Trying not to be disappointed. I know there could be so many worse things to happen.
