I got one GSD BYB Max that reacts to noise poorly, my other two working line girls Roxie and Erika are neutral to noise, Drago however LOVES to generate noise. He goes out of his way to bang things around, he'll take his stainless steel bowl and drop it repeatedly, he takes it to the top of the stairs and sends it down. he knocks thing over just to hear the noise. his favourite toy is my son's screaming monkey http://www.officeplayground.com/Slingshot-Flying-Monkey-P225.aspx?gclid=CNianurQmKsCFQ5y5QodZlyUKg
He doesn't chew it just shakes it or bites it just hard enough to let out a scream.

The other big difference is his total lack of grace and inhibition. My other three move thru the house efficiently and silently while Drago will bang into things and knock things over with his tail. You know he is going down the stairs because his tail is slamming both walls on the way down. If he decides he wants on the couch he'll jump right over the coffee table to get there. I'm trying to figure out how to "uncrate" him. He thinks anytime he is out of the crate he must be doing something energetic. Fortunatly when he goes into his crate at bedtime I hear a thump and he's asleep in seconds. In the morning he's quiet until I uncrate him and he's off to wake everybody up. I really want to leave the crate open, he's no use as a guard dog if I have to crate him to turn him off. If I don't supervise him he WILL get into mischief. any advice on how to do the transition would be appreciated.

You just described my younger GSD Trooper.
Classic bull in a china shop.
Both my dogs are outside 24/7 but Trooper can knock over the BBQ pit, slam into the fence/gate when he's at a dead run and has NO spacial awareness with people. I must step on his feet twice a day and he walks in front of me when I have my arms full of whatever. He then acts like the sky fell when I trip over him.
When he jumps in the back of my Pontiac Vibe hatchback he hits the seats in front of him like he forgot they were ever there. I think they are the only thing that keeps him from going through the front windshield sometimes.
On his runs around the yard he might slam into Thunder. He pays for that but it doesn't seem to carry over into the next 5 mins.
I've always been a believer that if you step on a dogs toes a couple of times they learn to stay out of you way. NOT Trooper. It's a new experience every time it happens.
A few day ago he was crashing into everything in the yard while he was chasing a hummingbird. The bird was totally in control and made him look like a big dufus, staying just about a foot or two in front of Trooper!
I think Thunder was just watching and snickering at the idiot!

At present Erika is still my dance partner. Drago is not comeing by it naturaly, the up side is he is a tug monster. loves the bite pillow and he alerts to strangers quickly

I used tethering. Up until he was about 2 Ryuk loved to knock into things on purpose (this is the dog who can run across a room littered with puzzle pieces and not touch a thing...I KNOW it was intentional). I've been lucky that I have a dog who loves to make noise using other things (he's not a barker, whiner, etc). I associated time out of the crate as time not always training or playing. If he got up I'd put him back down repeatedly until he was calm. I supplied interactive but hard to weaponize toys (everlasting treat ball vs tug-a-jug) or chews after he'd laid down. The chew was removed when he started trying to move around.

Now (FINALLY) at 2.5 I can leave him alone in a room and he's out at night. I still crate him if I'm gone during the day but I don't really have to. I've left him hours at a time out of his crate. When I'm home he's never in anymore but stays quiet and polite until training or play time.

He's 75 pounds already, tethering is going to be interesting

It almost sounds like he's being that way for his own entertainment. He may be getting the physical exercise, but what about mental? How much ob do you do with him? It's as though his brain is driving his body while its in overdrive to keep himself mentally stimulated. JMO

not enough

I had a "guard dog" type once that alerted on noises at night and people coming to the door during the day. I taught him basic security type tasks , like if I was upstairs with the kids and heard something downstairs, I would tell him to go check. He would run downstairs to the other end of the house and stop, then come back. Tell him "door" and he would run to the door. If I asked him ,"what's that?" , he would perk up and bark a few times and run downstairs.

If you want him to guard your house, teach him how, and the extra training will keep his brain busy to and give him more useful functions. Just something to think about.

Perhaps some obstacle course work to not only make him more aware of his body and surroundings but it will also stimulate him mentally and physically.

Dennis, he sounds like my Touche'......who was a total bulldozer. He got put to work helping me with clearing brush and hauling dead trees up to the firepit........he also got very good at digging up tree stumps. That dog was like a bunch of different heavy equipment all rolled into 1 98 lb. 4-legged dynamo.
Enjoy!!
