I have three small dogs and only one can destroy any toy we give her EXCEPT the Kong Wubba!  I love that she is stimulated and challenged trying to make it squeak, it is small enough for her to chew, she can pick it up and take it with her from room to room.  Prior to getting her the Kong Wubba, she destroyed every toy (and other things!).  She loves to try and chew through the toy to get to the sqeaky - she has had no success during the last six months since receiving her Kong Wubba from her daddy!!
