@rocky1 This is very interesting, if also alarming.
One of my favourite books is Who Killed The darling Buds of May?' by Catherine O'Driscoll - sent me from USA by a very well-known breeder.
It is subtitled along its spine with the words 'What Vets don't tell you about vaccines' - which kind of indicates exactly what it is about.
It always worried me that regulations insisted a pup have a rabies jab very early before being shipped to Germany although the Germans always said DON'T do it so young, we will do it here at a safer age. They re-did it anyway. Regardless of UKs DEFRA regulations.
Can't have been good for the puppy.
