The FurKidz Mighty Chomp Java Wood is a strong, natural, safe and durable dog chew that will help to satisfy your dog’s need to chew, preventing boredom and promoting dental health. It is made of sustainably grown and harvested java wood. The old, unproductive trees must be thinned, so FurKidz recycle the wood as natural chew toys. The wood is caffeine free and is simply dried and sanded to give a healthy and satisfying chew.
