This sounds more like a leash reactiveness issue, more than actual aggression.
My hubby's dog is like that; an absolute PITA sometimes on the leash, and more so with him than me; I think she differentiates between the fact that I am consistant and naughtiness is just not acceptable, and she doesn't have to try to 'be in charge' of situations while I am handling her. Hubby on the other hand is not always so consistant, and so somedays, she will be okay, and others, she can't even handle seeing a dog who is a LONG ways away.
My advice would be to seek out a behaviorist, not only for the dog, but for yourself; there is obviously something in your actual demeanor in which she finds that she needs to take control over certain situations. Find out what that is, and I bet your dog will make a complete turn around. Good luck with her! That she is fine with dogs in daycare and boarding is a very positive thing.
