I adopted my now 2 year old husky/shepherd mix from a local shelter about 6 months ago. He was a tough case as he had been in the shelter most of his life and had no training (if you know anything about husky's, you know they are hard to begin with!). Through lots of professional training, we got his behavior under control but his chewing is unending!! He destroyed toys and other chewys in 20 minutes tops then would move on to furniture. UNTIL THESE CHEWYS! I went to our local pet supply store and they suggested these. I have never been so excited over a dog treat/toy! One of these babies will last him DAYS, and he LOVES them!! They are the only ones that last and our furniture has been completely left alone! There is no residual smell either. He also loves the Buffalo Horns, he has had his for over a month and it's still going strong-but warning it does have a sulfur smell when he's really chomping on it so it's a "floor only" chewy. For SUPER MEGA chewers, these could very well be your solution! They were for us!
