Dr Dodds feels that a half dose is probably fine and safer, but they don't do it for rabies, I think she is implying they don't because of the law. As her and Dr Schultz's research is showing rabies titres are good for at least 5 and likely way more, years.
Vets halve vaccines in small and toy breeds because they are finding the dogs are having more adverse reactions to the vaccines (as the research shows). Co-incidence?
The problem with vets like peds is they only know what they have been taught about vaccines, which is precious little, so it isn't surprising they tout the official line. The AVMA is all but bought and paid for by big pharma and the pet food manufacturers, so nothing new there. There are some vets like Dr Schultz, Dr Dodds, Dr Jordan, Dr Pitcairn etc that actually think for themselves.
