I had a bitch a few years ago who had her annual booster, she was around 8 years old at the time. We came home, and she immediately went down the garden and was sick. She continued to be violently sick and had diahroah for the next hour or so, until there was nothing else left inside her and the noise she was making was horrific. I called the vet and he met me at the surgery, he gave her an anti vac and wanted to keep her in overnight on a drip. I thought we were going to lose her and wanted to bring her home, but had to syringe fluids into her every day throughout the night. She went into the vets the next day to be put on a drip. She made a full recovery, but needless to say she never had another vaccination in her life.
I hope your dog pulls through ok, I would ask the vet to contact the physicians at Schering-Plough for advice first thing in the morning. You could also contact Catherine Driscoll who is very knowledgeable on the subject of dog vaccines and very helpful.
her email address is:
