The Dog’s Life FetchStix is made with natural rubber from the sap of rubber trees, so it's non-toxic and 100% biodegradable. They’re free of any harmful chemicals like BPA, phthalates, latex and vinyl and are super fun to play with! They’re durable and fun for moderate chewers and persistent chewers who like the springy resistance of this more flexible chew toy. Durable, natural rubber retains shape and stands up to tough chewing. The FetchStix combines shapes and textures to create an irresistible chew-feel with a bouncy action. Our FetchStix is cleverly designed so it’s easy for even pups or senior dogs to grasp by mouth or hold between the paws while chewing. Made from our natural rubber which is durable enough for persistent chewers yet soft and chewy enough to satisfy your dog's chewing impulse. Built for moderate chewers, FetchStix is safer than a wood stick and because it also FLOATS in water, it is perfect for fetch and water play. Natural rubber is a renewable, sustainable resource. Help protect nature for you and your pup. Dishwasher safe!
