Query: Quite the opposite...Not for extreme chewers

I bought this item thinking it was going to be any different then the other kongs, but I was very wrong. After my dog got all the peanut butter from the inside, she chewed the thing right up. It didn't even last for 15 minutes before she completely destroyed it. This is not a good product for extreme chewers. The only thing that's lasted on my dog is the nylabone, we are going on 6 months with that. If you have an extreme chewer, do not buy this item. It will be a huge waste of your money.
