I have an 85 lb Pitbull and he loves to chew on those kind of hard bones but the meat flavor and scent is only in the middle the knobs on the end are just plain nylon and yes it is taking him a long time to get through them but little white fibers keep coming off I find them on the couch and he nibbles and tries to eat it so I believe he's eating the nylon and still has yet to get to where the beef flavor is in the center he doesn't chew from the middle he goes from the end all of his other chew toys he has he has demolished this one not so much I only gave four stars because my dog doesn't like it so much it is a very good sturdy toy though and has a good beefy smell. And a fair price.

Long lasting and the dogs really like them

Color: 1PC-Beef-Red

I purchased these over a year ago and they are still standing up to 2 heavy chewers and a medium dog.

For aggressive chewers means just that!

Color: 1PC-Beef-Red

Large size means large. Very well constructed and made for the aggressive chewer I have at home.

Not completely indestructible but definitely long-lasting with plastic bits everywhere

Color: 1PC-Beef-Red

It's destructible it just takes a long time and tons of tiny little plastic pieces everywhere and even in your dog's stomach would not recommend due to wear and tear on dog's teeth and the plastic chips off.
