Abstract: A dispensing system (200) for chewable pet toys (100) contains multiple toys and dispenses them at intervals determined by one or more modes of operation. A display (220) and keypad (400) are used to enter programming data into the memory of a microprocessor (315). When the system is in operation, the display indicates progress through the program, the mode of operation whether MANUAL, RANDOM, or BMOD (behavior modification), the time elapsed, and the number of toys remaining. At various times, sounds emanate from a loudspeaker (320), vibration emanates from a vibrator (328), light emanates from a light source (325), and odor emanates from an odor generator (327). Toys are dispensed down a ramp (225), at predetermined times, or at predetermined times modified by random numbers. Predetermined dispensations permit modification of the pet's behavior (BMOD). Random variations on a predetermined schedule of dispensations (RANDOM) prevent the pet from memorizing a schedule.

Abstract: A closure (400) for a hollow pet toy that holds edible materials contains a cut-out relief (410) that extends above a desired shear plane (170). When fully inserted into the large opening (110) of a pet toy (100) the top (420) of the cut-out relief lies above the shear plane, outside the toy. If the pet bites into the closure or wets it with saliva, it will break or disintegrate into sections (510, 610, 620) which are too small or too large to lodge in the large opening of the toy. Thus when the pet bites or wets and breaks the closure, none of the pieces of the closure can lodge in the opening of the toy and prevent the pet from reaching and eating the contents. An alternative embodiment is provided with a cylindrical top (710) which can be eaten by the pet, cannot lodge in the pet toy opening, and which can be printed or embossed with a logo.
