A freind of mine who hunts exclusively in snake country in montana,who also has a vet there,he calls the vet there and has the doses shipped to him for pre hunting season dosing(does them himself),He told me the doses are 15 dollars per dog.This fellow is awesome, Retired full bird col from the army,80+ years old and full of fire with 3 VERY VERY well trained pointers that would put most field trial dogs to shame.He hunts for a month straight on sharpies.His hunting partner had one get bit that was vaccinated for it,the dog spent the night at vets for observation and was then hunted the next day.
