These bones LAST (at least for my 55lb Black Mouth Cur). I've bought another brand's bones for a couple years because my dog only likes bones she can actually eat (and taste good) and so having ones that last and can't be eaten like a Milk Bone is crucial to me. I didn't actually think she would even like these because they're very different her norm but she's loving them! I bought 3 packages of the other bones and now I wish I had gotten several of these instead to last her a week or two. So far, these last her at least around 2 hours which is crazy. I also got bully sticks to try this week (in the name of long-lastingness) and she couldn't be less interested - These are, in my opinion, as good as it gets for dog taste appeal, durability against consistent chewing, and not making a terrible mess like some products do. I was honestly just hoping they'd last 30 minutes or so but again, they last hours. The bone she is chewing now was given to her about 3 hours ago and has like.. almost all of it left, and she's been busy at it nearly the entire time besides a potty break!

We like these for our dogs because they are the only chew treats that do not make my dogs sick. We get the ones that are for active chewers because our dogs are quick to chew through any treat. They do chew through the active tour ones in under five minutes, however it seems to satisfy them and we can't find anything else to last longer.
