I have a GSD male puppy and I purchased this when he was 7 months old and destroying EVERY toy I brought home!!! I even tried a tractor tire which he was able to disintegrate! THIS TOY...I LOVE IT!!!! He can play with it, gnaw on it, tug on it for hours and it has held up to his high-energy and rough destructo manner!! I would recommend this toy to ANY dog owner for hours of pleasure and no worries!!!
