Liz it sounds like you are making very good progress with both of them. Thats great, I think with common sense you can do it on your own without the pricey expert. We have the same trouble with Daisy and Perry, can't walk by any dog or person without them barking and attacking. If we walk one of them they are fine, it's only when we walk them both together. We are working on that, kind of let it go, but it is embarressing when you take them somewhere so trying to take some control. It just takes a lot of repetition and time.
