NON-TOXIC NATURAL RUBBER: Made of 100% natural rubber, the chew ball is durable but won’t crack your dog’s teeth like some hard plastic balls. It’s suitable for aggressive chewers, but it’s gentle on their gums. Dental Chew Ball: This chew toy has dental ridges that help keep plaque away and reduce tartar build-up. Its soft material can soothe teething discomfort in puppies. Real Beef Flavor: The beef flavored toy can provide mental stimulation, stimulate animalistic instincts and prevent destructive chewing. It’s a great choice for playing fetch with your dog.
