Thanks for the input Mitch, good to see some facts being used as opposed to just opinions. I agree about the lepto being one to consider, but the vaccine against it doesnt prevent your dog from fghting off the disease fully, only lessening its severity thus improving the timescale in which to get anti biotics into their system. Its also one that even vets dont always recommend having unless there is a high incidence rate in your area so if according to the vaccine manufacturers vaccines for parvo, hepatitis and distemper are meant to be administered every 3 years then surely that shows that lepto is considered low risk even to them?
Im sure seeing these diseases is horrific, but in the same way we arent talking about cancer in humans, its no where near as prolific as that, you can argue that vaccines are the reason behind this but if you look back in history these diseases where still not as common back then. Research wont be done whilst pharmacutical companies are making millions of pounds a year, its in their interest and vets interest for annual boosters to be a requirement! Ill ask you one question Mitch as you have just stated, you believe the three year vaccines to last the lifetime of the dog, you have learnt that from your vetinary course.... so will you advise your clients pets to continue with annual boosters? Will you advise them to come in every three years instead? Im guessing not.
