border collie,dogs

Question
will my border collie protect me?
details: see i have a border collie female. i adopted her. it was actually accident i met her. see a year ago i begged my parents to get me a border collie. FOR A YEAR! they finally said yes but there weren't any male dogs. i got a white german shepherd instead. we were in houston at the time now brownsville, i found  her. i was looking supplies for a project, when we saw some dog. my mom said we could go look at the dogs. so we went and i saw sophia (my border collie) and her brother, jake. i walked both dogs and liked sophia. i begged my mom and she said yes, after some time. we brought her home and yeah had her since.
info about sophia: she is friendly doesn't really growl only barks., and is sweet to me and my family.but there have been times when she's with me and then coco(my white german shepherd) came and he was stepping on my foot so i said OW! she snarled at him and bit at the nout (not too hard though) then came back. idk if it' s just playing or to protect me. she's a year old. and yeah sorry this is so long. i want to know if she would protect me, like if someone broke in or attacked me. she follows me around and listens to me. since day she did that. once someone was walking by and she flashed by (in our backyard) barking i went and told her to stop she did and was submissive. so yeah. i think she thinks of me as her master. do you think she would protect me? again sorry for it being so long. :)

Answer
Both your shepherd and your border collie have the potential to protect you.  They both have protective qualities in their breeding.  If you were being attacked either would probably protect you.  You have to know though, that unless they are trained for protection, they would not be a match for a human who knows how to handle dogs.
