Two clinical studies on dogs performed by Jerzy Gawor, DVM, PhD, DipAVDC/EVDC and his team have shown that ProDen PlaqueOff® Powder significantly reduce the formation of plaque and tartar. Data from these studies were submitted for review by the Veterinary Oral Health Council (VOHC®), which awarded the Seal in the VOHC "Helps control plaque and tartar" categories. Swedencare announced that ProDen PlaqueOff Powder is now permitted to carry the VOHC® Accepted Seal.
