This invention relates to a modular dog toy comprising three disparately sized and shaped components, each having a hollow cavity for the reception of foodstuffs. The components each comprise a male connector and a female connector. One of the components has at least one additional connector about its surface. These three disparate components may be connected in a variety of different configurations to modify the difficulty of obtaining the food for the dog. This allows the modular dog toy to be tailored to suit the requirements and physical abilities of the dog.
