There must not be any veterinarians with PD on this list. I was married to one ( w/o PD) for 12 yrs. As far I know it was developed and used as an emetic---We used it for dogs thst had eaten slugbait, popsicle sticks, etc to get it out of their bodies fast. I cannot imagine taking it --ihese poor critters were sick and appeared to be dizzy until it wwore off!! If I am ever offered the stuff, I'll pass, thanks! Rebecca Hudson
