Our dogs are both under 25# and they love to chew on these and they last for days. They keep there teeth clean and satisfy their need to chew.I found that bigger dogs eat them too fast. I think that's not good for them.My English bulldog went through the bag quickly. They seem 'powderly' when my dog began tearing them up and make more mess than expected. Also, I caught her trying to cough up the middle part that was partially in her mouth and throat; not sure if these are very safe. Based on my experience, I would not purchase again.matters not what I like or dislike about this product. what matters is that our dog enjoys them & she doesI have very picky pups. Your chew bones are just the right size and help keep the peace!My dog really seems to love these bones. She is a large breed German Shepard and she is still a puppy meaning she can be busy and destructive. These Boone’s keep her distracted and last her 2-4 days which is amazing. She goes through bones very quickly and can destroy some bones in a matter of hours! These also have the added digestive bonus. I notice when she has her bones, she goes super regular. Overall a good deal for some pretty good bones especially for large dogs.My dog loves these! Perfect size! Best rawhides!!The bones made the dog sick. He vomited. After we could not return the bones and get our money back we threw them away. We will never purchase again. The packag was open when we received it as well.Good quality bones. I have a large lab mix who can chew through the cheaper bones within an hour. These last at least a couple days. Would be nice to get more of a discount since buying in bulk but I'd still rather spend a little more for bones of this quality that will last longer. I recommend these bones!
