My GSD she is eating little stones

Question
Hi.my GSD she is eating small stones,can anyone help me stopping this bad habit.

Answer
As long as she sticks to fairly small ones, they should pass harmlessly.  The problem is with slightly larger ones.  They could choke her or block her digestive tract.  The dangerous size is likely between an inch and 2 inches.  There isn't too much you can do except try to keep her away from them.
