Nápreva K9 for dogs is based on the same proprietary, pure terpene formula we use for our human products. Veterinarians and owners use it to help dogs suffering with chronic pain from aging, arthritis, sports injuries and many of the same conditions as their owners. They also say it also works for anxiety, poor appetite and improved sleep. Nothing in Nápreva K9 has known negative side effects. It’s not addictive. Dogs fed well-formulated diets eat terpenes, including those found in Nápreva K9, every day. But the precise combination and concentration of terpenes in Nápreva K9 ensures rapid relief and maximum benefit with minimal risk.
