Apparently, German Shepherd Proof
Reviewed by Anonymous from Southern Arizona on Saturday, November 12, 2016
My 4 dogs-3 German Shepherd mixes, plus a Golden-like these toys and, miraculously, do not destroy them quickly. For example, they destroy an average "stuffie" within an hour, and a "super, indestructible" stuffie within a few days. The nerf toys usually last for a month or more: nerfs last longer than any other squeaky dog toy I have ever purchased.
