Snack time just got more fun with the Cookie Cup system! This long-lasting dental treat cup grinds down like a natural bone to help clean the teeth and gums for a healthy canine smile and fresher breath. It's also fully edible and digestible with all-food ingredients and no wheat or corn. The deep cup enables you to stuff it with your dog's favorite healthy fillings, like mashed fruit, yogurt, or nut butters. The Cookie Cup Jar is made of our proprietary dog-tough material that's puncture and tear resistant to withstand strong chewers. Create a snack time interactive challenge by inserting the Cookie Cup treat into the Cookie Cup Jar and filling it with the healthy treat of your choice. Freeze the stuffed treat and toy together for a cool snack or to increase the chewing challenge.
