Keep socializing i'm sure there were signs which means she also needs some training, id definitely consider some training classes. but also dog parks where both small and large dogs can play together is 99.9% a no-no even if that dog didn't attack the dog can u imagine 90 pounds of dog trampling over a little chiweene(sp) even if just trying to get a ball... im pretty anti dog parks and pro play dates as Crnosrce brought up
