What breed

Hi this is my pretty girl that i found thrown out on the streets when she was like 3 months old and she is almost two years old now.I have always been fascinated on what breed she is,but i live in a place without really good dna tests and they are kind of expensive.I ve always know that she has a shepherd in her and people always think she is a purebred,but when i tell them she is a stray they all get surprised haha.Generally want to hear your opinions so thanks in advance!!
