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.

Great Product!!!
Color: 1PC-Beef-Red
This is the first toy my dog has not demolished. I need to buy more just like it just in case something happens to this one. It's worth every bit of the money I spent on it.
