Abstract: A pet treat comprises a frozen mixture, the frozen mixture including protein, water, and a therapeutic substance such as glucosamine and/or chondroitin. The frozen mixture can be homogenized and further include entrained air bubbles, and optionally may have a meat flavor such as beef, chicken, lamb, or pork. A support structure, such as a stick, cone, push-up tube, or cup, can be provided to facilitate provision of the pet treat to the pet.
