Yes, I have a dog who has been diagnosed with this. She has had a cerebrospinal fluid analysis done and it has has been confirmed, the condition is extremely rare, however, that doesn't help when it's happened to your baby.
I'm currently doing a lot of research on it, the company that makes the vaccine that was used guarantee it or they will pay the vet bills up to $2,500 and if the dog dies they give you $1,000 to buy another one - it's an absolute disgrace, do they not realise they are not disposable objects :-( But of course it's so rare they can afford to pay out now and again, in the meantime my poor baby has a death sentence.
