That was my concern with splitting them. Three times the preservatives and three shots for each round isn't what I'd be doing.

But I also have some reservations about just doing half b/c it takes a certain amount to get an immune response and has nothing to do with the size of the dog. So if it could be split for a small dog, then it should be able to be split for a big dog. While DOI is studied extensively and the research is available to pet owners, some of these other things are not. If she ever does a study or seomthing, I'd love to see it (or any study by a vet school, etc.), but my understanding is still that it can't be split, so I would not take the chance with my dog.

I don't even know all the companies that make rabies vaccines. The ones I'm thinking of are Pfizer and Merial, but Wyeth may make one also. So I guess we could ask them all what the difference is in their 1 and 3 year vaccines.
