Well, if your puppy is around 4-6 months old and a aggressive chewer, finish chewing pedigree dentastix within 2-4 minutes. Then it's a good option for you. There are 3 hard bars, even after 2 hours my puppy is still chewing it. One bar at least lasts for 3-5 days( 2-3 hours chewing per day). The bars are hard.but my pup enjoys it. She and me very satisfied with the product. Thank you.
