“We are focused on delivering safe and effective products like Safe-GuardR and Safe-GuardR Power DoseT to horse owners so that they can keep their animals in peak health, ” said Stacy Basinger, retail marketing manager for Intervet/ Schering-Plough Animal Health. “We understand that the bond between horse and owner is unique and very strong. Equine parasite infection is the single biggest health risk that faces our customers and we are committed to educating horse owners about how to get rotation right. Parasites are just a fact with horses, but with the right program, it is easy to control. Our website, GetRotationRight.com, is packed with essential information about how best to implement a deworming program.

In keeping with our healthy horse philosophy, we continually strive to come up with promotions to better the bond between horses and people. This horsemanship clinic sweepstakes is just a small way that we can thank our Safe-GuardR customers while providing a truly life changing experience for both horse owner and horse.”
