The SPOT Love the Earth Coffee Wood Dog Chews are skillfully hand-made from branches of coffee plants that no longer produce coffee beans. This by-product of coffee farming provides a safe, strong material that is 100% natural, sustainable and free from chemicals and artificial ingredients. Coffee wood is naturally dense and heavier than most wood. As dogs chew, the stick whittles down slowly, softening the fibers making it less prone to splintering. Resilient coffee wood chews provide satisfying and long lasting enjoyment. Dogs instinctively chew to entertain and occupy themselves. As they chew, natural hormones are realeased in their brains that help to relieve stress. While chewing, the wood is softened and flakes away exposing tiny, harmless fibers that act as floss for healthy dental hygiene. Daily chewing also exercises jaw muscles.
