First, please answer some questions for me (copy paste questions with answers into followup form)

*  How long have you had this dog
*  Is she spayed, what age
*  If you had her from early puppyhood, what sort of socialization did you do
*  What methods have you attempted to stop this behavior
*  Describe "goes after any dog she sees" as fully as possible
*  Has she ever caused injury to another dog
*  Are you upset when you see another dog approaching

I need as much information as possible in order to help you counter condition (or attempt to counter condition) your dog.  Thank you.
