About the VOHC

VOHC exists to recognize products that meet pre-set standards of plaque and calculus (tartar) retardation in dogs and cats. Products are awarded the VOHC Seal of Acceptance following review of data from trials conducted according to VOHC protocols. The VOHC does not test products itself.

The VOHC Seal is displayed on products that have been awarded the Seal.

Regular use of products carrying the VOHC Seal will reduce the severity of periodontal disease in pets.
