EquinePure Pellets are pine horse stable bedding pellets made from the pure heart of pine (that’s the soft wood inside of the trunk). That means our pine bedding is 100% bark and tar free. Also, unlike sawdust and shavings, there is no dust, no shards and no contaminants in EquinePure horse bedding pellets. The low resin and bark-free content of the heart of pine means higher absorbency, longer life and a cleaner, safer, healthier environment for you and your horse.
