Element of Variety
This product was a Godsend for entertaining our 15-month-old Boxer-Shepard mix. He has an extremely short attention span, but the intermittent movements of the device and the sounds emitted from the cell phone app kept him confused and engaged. He ended up treating it somewhat like a friend and carried it around the house with him. Our dog is a super-chewer, so we're always buying the most durable products possible - most of which last 5 minutes.
