Thanks for all of the insight everyone!
Like Toby, I have good days and bad days. I try to keep my head up but was feeling very frustrated and down yesterday.
I thought about my situation with Toby and everything everyone said.
Toby is making more progress than I let on, its just hard to see when you get focusing on the negative. And as everyone pointed out, we've only had him for two weeks!
I just want to be clear though, when Toby explodes, he is not in the least bit aggressive, I'm not sure that I ever mentioned that. There's just a lot of lunging, barking, whining and some times yelping. Toby can quickly and easily work himself into the highest level of anxiety if I ignore his behavior, but I hesitate to use the words 'red zone' because some people relate those words with aggression, which he's shown no signs of, although his lunging can be interpreted as that by passers by (Some idiot on an electric scooter actually honked his horn at us when Toby freaked at the sight of it. Gee what a BIG help!

).
That being said, while he still barks, lunges and generally frustrates me, now that I'm in a better state of mind myself, I realize that his anxiety isn't reaching this heightened state at all anymore, that his BAD reactions are still only a fraction of how he was. My experience is with sensitive dogs and dogs who are noise sensitive, but I've not had to deal with this level of reaction before.
When I was walking him this morning and watching his reactions, I realized that a small tug on the leash and praise was enough to get him back on track some times. On a busy road he did very well walking past a large hydro truck on the opposite side, doing work on the hydro lines. He growled and fixated on it a bit, but when I gave him a gentle tug on the leash and kept going, he looked away and returned to my side.
Last night I jogged with him, which pretty much guarantee's more barking and lunging, but he's slowly doing better. I found much the same thing, since its harder to give treats while running. When he barked lunged, I pulled on the leash, which brought his head back around (the gentle leader is such an AMAZING tool for dogs like Toby) and enabled him to focus again.
Toby had a small set back Monday night. We brought him to my parents house for the first time and my mother was cleaning out the family room. She had this sun shaped decoration leaning against the back of a couch, which Toby hit as he was trotting by. It scared the heck out of him and he was very subdued and stayed by my side for the rest of the visit. Today he noticed the wreath on our door and freaked, I think because it resembled the sun decoration. He was good about sniffing it but was still afraid of it. Oh well, what can you do.
