Great for Chewers!
Flavor Name: Chicken, Size: 7 inch (Pack of 1)
Purchased for my German Shepherd Pup a few months back and it’s still going strong! It is by far his favorite chew toy. It clearly lasts a long time. It’s a nice size with some weight to it. Good for them chewers!

Not for aggressive chewers
Flavor Name: Bacon, Size: 5.25 inch (Pack of 1)
This bone is noticeably softer than most chew toys I've bought. That may be a positive for some dogs, but my dog was able to break off fairly large pieces, which made me nervous. It might work well for light chewers, but I wouldn't recommend it for aggressive chewers.

Great for aggressive chewers
These are some of the strongest bones I've ever seen. I have aggressive chewers and my puppy loved this bone. She lays on the garage and goes to town on it, not making any marks or chards or breaks like we do often have to deal with. They are long lasting as she has been chewing on it for a month now - well worth the money.

Great chewy for my dogs
My 3 dogs love these already. I smeared peanut butter on one side and passed them out. My 2 that aren't crazy active or aggressive chewers enjoyed the PB, then were done for now. Energizer bunny dog has now claimed all 3 and is alternating which one she chews on. Great buy for keeping them, especially her occupied.
