Abstract: Dog toys, some of a type including a rope and others not including a rope, include a biting object with a hollow interior cavity within a bounceable shell made of a tough resilient material, the biting object having at least one squeaker device within the cavity. The squeaker device within the cavity is either flush-mounted at the outer surface of the biting object or is entirely enclosed therein. Some embodiments are tug toys in which the rope extends into the cavity through a single rope opening in the shell and terminates within the cavity. The shell of the biting object preferably has a outer surface with a felt-like cover and most preferably forms a sphere.
