Fun plush character toys with recycled water bottles inside. Dogs love the cute toys, and the crinkle of the replaceable water bottle provides hours of fun. Simply remove the bottle cap and rinse out the inside of the bottle, then insert the bottle into 1 these 3 cute & cuddly Bottle Buddy characters (being sure to dry the inside of the bottle first to prevent mildew). And there you have it: your dog’s new favorite toy! Dogs love the feel of the soft plush material on the outside, and the crinkly sound of the plastic bottle on the inside gives it an extra kick. When the bottle loses its crinkle, simply replace it with another bottle.
