The Veterinary Oral Health Council ensures quality and accountability in pet food. First developed in the 1980s, the VOHC was actually launched in 1997 after much consultation and collaboration with a number of veterinary bodies. It is currently based out of Philadelphia. The VOHC Seal of Acceptance, now a recognized symbol worldwide, was first awarded to Hill’s Pet Nutrition for its Hill’s® Prescription Diet® t/d® Canine pet food in 1998.

The VOHC’s purpose is to recognize products that meet pre-set standards for plaque and tartar control in cats and dogs as well as authorizing use of the VOHC Accepted Seal on these products.

How the VOHC Works
The VOHC reviews data and materials submitted from clinical trials, conducted according to stringent VOHC protocol.

What Does the VOHC Seal of Acceptance Mean?
Products awarded the VOHC Seal of Acceptance have passed their review process and met the pre-set standards. These products live up to their claims to aid in controlling tartar and plaque development in dogs and cats.

Why Is Plaque and Tartar Control Important?
More often research studies are showing a connection between oral health and a pet’s overall well-being. The build-up of plaque and tartar can cause gingivitis, which if not treated, can turn into periodontitis. This can set off a ripple effect of poor health throughout the body as bacteria circulates in the bloodstream. Periodontal disease is a major contributor to poor systemic health and veterinary studies in dogs indicate changes in an animal’s heart, kidneys and liver can all be linked back to poor oral health. By controlling plaque and tartar, pet owners reduce the risk of their pet developing gingivitis or periodontitis, giving their cat or dog a better chance at overall good health and wellness.
