"We reluctantly accepted a sample of these when they first appeared on the scene, reluctantly because one of my girls has digestive issues and is very picky. Well, she loved them and they are a god-send for our other girl who has a big tartar problems, even with regular dental cleanings and brushing. These are excellent when traveling, which we often do with our girls...5 trips alone last year! What convenience! We use these to supplement their diet at home, in addition to high end dog food & many supplements. People often come up to us and remark how healthy they are...must be doing something right :)"
