If anyone will come up with an absolute cure for PD...it will probably be a vet. I have always said..if I get sick...take me to an animal doctor...I trust them more with all the background they have and their caring ways . I think they actually have more training...dealing with many kinds of animals and most are not specialists...they learn it all. Vet research is not so restricted by the government, because they are ONLY dealing with what the government would consider a lowly creature put here for our use anyway. I had an uncle that was a professor of animal husbantry at Penn State and know they have a superior program there for students. GO PENN STATE!!
