I believe there is another hidden agenda on not approving the rabies vaccine for the species canus lupus. We participated in the original blood samplings which Nick Federoff had headed up to help resolve this issue. I believe the facts stand for themselves. What is interesting is there is no guarantee that the vaccine works on every breed of dog since each individual breed was not challenge tested. If there was a huge genetic difference between the breeds of dogs and wolves, then offspring would be sterile and they're not.
