Query: Not for hardcore chewers

I bought this product for my 9 month-old, 30lb puggle. She is a crazy chewer so I figured it would keep her busy for at least a few hours.After 5 minutes, she had chewed a few tiny chunks off of one end. After 10 minutes, maybe half an inch max was missing from the same end.After 15 minutes, 90% of the bone was gone. I don't know what happened but she must have figured out a way around the chewing. For the next 24 hours she was obviously in discomfort as her body passed the chew, and she drove us crazy acting out because of it.This product is nothing more than a really expensive dog biscuit. DO NOT BUY if your dog is an intense chewer. Light chewers may be able to make it last, but honestly I wouldn't risk your dog's health. Stick to original nylabones.
