@carrow83 - Welcome to BYH! I've moved your post to it's own thread where it will get the attention that it deserves and where it will not detract from the other thread. I don't know much about working dogs or LGDs, but I'm sure that some of our other helpful members will be along soon.
Don't have experience but I think it would depend on if the LGD understood what was happening. If not it would probably go after the other dog(s), simply cause it would see them as a threat. It would also depend on the individual dog, some would do better than others.
