Deceptively light and incredibly strong, the Cirq is a super-durable square-in-a-donut toy that can be thrown like a disc and is easy for dogs to pick up and carry. Part of the goDog Rhino Play line, all toys in this collection are exceptionally durable to withstand rough play for long-lasting fun. Created to encourage play between dogs and their people, every purchase helps support charities that promote play and work to enhance the bond between humans and animals. Rhino Play toys are made from PopFoam, a non-toxic, lightweight and durable material that stands up to tough play. This material is made with environmentally sensitive manufacturing processes and the toys all meet child safety standards. The Cirq Junior is ideally sized for smaller dogs.
