If anyone has had to nurse a dog with one of these disease they would definetly vaccinate their dog!
The same applies to "if you have lived with a dog with auto immune disease triggered by a vaccine, you would not over vaccinate your dog".
It is proven that vaccinating every year for every disease is not necessary - so why do it and risk over vaccinating ?
I would also like to point out that many vets would not recognise a vaccine reaction - and certainly would not report it. Most owners do not realise that a dog being "off colour" is a vaccine reaction - thats just the smallest of reactions .....
Cockers are genetically predisposed to vaccine reactions - even David Sutton (big cheese at Intervet) has admitted this - in an article I was involved with in Dogs Today in June 2001 he admitted that cockers are more prone to reactions than some other breeds.
I'm not saying don't vaccinate, I'm saying don't over-vaccinate.
