Can I give these more than five stars? Please?? They truly deserve more than that! I have bought these bones for the last 2 years for my pitbull mix, who is a very aggressive chewer. Her favorite thing to do is just lay and chew. These bones last FOREVER! She can lay there and chew all day long and they will last her MONTHS! It’s honestly amazing! These are the best bones we’ve ever given her and they are the only ones we’ll buy her! Not only do they last forever, they’re safe and natural too! Best product ever!
