I have a particularly destructive girl, seek and destroy all new toys is her mission in life! The black kong is the only Kong that has lasted, even then we are missing a few bites here and there. I do keep this and marrow bones in the house. Then when we are training or playing in the house together, I pull out the soft squeaky toys and ropes where I can monitor the situation. The other toy, outdoors that my boy loves is the 10" indestructable ball (boomer ball). I am considering getting a soft ball for inside the house, but will have to keep it picked up when alone, or Saga will lick at it until it is in pieces.
