The Honeymoon is Over

With Neon that is. The past week and a half he is testing every boundry I have set for him. The jumping and nipping behavior is back, obedience has gone out the window, and to make things even more fun, he's decided to become destructive when I'm not watching.
I expected this eventually, but he's become a hurricane! He's lost the right to be uncrated when not supervised, and we are going back to NILIF.
How long can I expect this to last? Argon's little rebellion was nothing compared to Neon, and only lasted a few days. Neon acts like he is just getting started.
It's frustrating, but I know if I'm calm and consistant, he'll shape back up eventually. How long have other dogs gone through this, and do you guys have any suggestions to keep us both sane?
As background, he is almost 2 years old, I have had him almost 3 months. He goes to daycare under my supervision 6 days a week and gets plenty of mental exercise. He does have some fear issues, which I think are playing into this. It does not appear to be SA, thank god, just a sort of general brattiness.

Ah, teen-aged "testing"
Most of my fosters go through this faze. Some dogs it lasts longer (much much longer, lol), some dogs shorter, but I feel as if the average is around 2-3wks. you've had him about 3mos - this sounds about the time they start it
I know how frustrating it can be, take deep breaths and be very consistent, and as calm as possible. I'd try to do training "games" to keep it upbeat and fun for both of you. I like "go wild and freeze", or turning the furniture and household items (broomsticks, chairs, etc) into a miniature agility course (oh the roommates LOVE that HAHA!). It sounds outrages, but it seems to teach boundaries. Like teaching a dog to speak on command so he will learn quiet.

I'd say...increase exercise and more obedience practice so you can direct him to more constructive things to do when he's getting into those moods....more structure. It's not uncommon for dogs to regress into crazy behavior. Toker still gives me a run for my money and she's 8 or 9 years old. You'd think she was a puppy sometimes....a very intense but sweet dog and generally well behaved, but she can throw surprises at me every now and then...much more so than my Chis.
