Did you try the method Ryan mentioned?

My dog is still very dog dominant but he
definetly has backed off a lot where I
can walk/train him among other dogs.

(I found a great Trainer)

I walk him at a heel with a loose leash,
if I notice another dog close by, I grabb the leash with both hands, (making shure the leash is LOOSE)and I keep on walking my normal pace so he
will not even know what I have just done.
If he starts to lunge/ or growl, I yell "OUT" and he gets a very strong quick jerk/release correction, and I keep on walking.
If he walks nicely, I am quick
to praise him.

Keep us informed. : )

As Rachel mentioned, make shure you are
doing the jerk/quick release correction correctly.
