I buy these bags because they are biodegreadeable and really inexpensive. We also get her these sticks since they were the cheapest option per stick for us. We break them in half before giving them to her. I don't know if they help her teeth, but she goes nuts for them and they helped us train her to be alone when we are at work. *Nylabone nutra dents are also gluten free, which we try to stick to when giving Molly any food or treats.
