Hibiscrub, is anti bacterial and anti fungal, great stuff and i also use it for cuts ect on horses and my dogs. I hear the NHS has started using it, so it must be doing some good.
First thing i would do is see another vet for a second opinion.
we have all been there buddy, nothing to worry about.... just have the kettle on and biscuits...
Oh yea, and look out for the "were do u keep ur keys" trick question...... Just say I cant tell you !!!
Great night out with "The Duncan" we bagged a charlie and saved a few lambs for the farmer.
