We hear that the initial post mortem results are back. They are, in effect, useless to us. The body of the dead puppy had been sent up to Glasgow University - specialists in the canine herpes virus. The gross pathology tells us that the pups died of fluid in their lungs. We still have to wait for the result of the further post mortem in which they have grown cultures. The theory is that once we know what is wrong, the vets can treat it.
