I read quickly and am not sure that I got the whole gist of the thread in doing so.  On one hand I read something about no medical issues, on the other hand I read this in a post near the end:

"she has been on 2 bladder muscle control meds and multiple antibiotics for UTIs"

This post really strikes me as more of a medical issue, and that is because we had serious potty training issues at our house with the latest pup that sound similar to yours.  None of it was due to her inability to learn, but more with a condition called puppy vaginitis concurrent with what I believe most would call an innie vulva.  You can google both of those for information.  Anyway, an innie vulva is a vulva that isn't pronounced, but rather tucked into fat folds and harbors bacteria.  Since the anatomy will not change until the first heat cycle, when swelling occurs, you can end up in a cycle of UTIs in the meantime.  I believe pups have can have puppy vaginitis, without the innie vulva, as well.  Anyway, this is my experience with my youngest pup, and from the reading I've done--it is very common.  I think my girl was on antibiotics 5x from 2.5 to 7 months old.  As she aged, she got better about holding it longer, but still had numerous accidents every day during that period...and we put her out like clockwork--sometimes as often as every 20 minutes.  She also had occasional pooping accidents, but I attribute that to her not really knowing what was acceptable, due to a condition that forced her to pee somewhat uncontrollably at times.  She has been UTI free and completely potty broke for the last 2 months, but despite my hard surface floors, it was a frustrating time.  I do not know if it did any good, but I did and still am supplementing with Acidophilus chewables and Cranberry gel tabs.  Some folks swear by that.  So long story short, I am NOT saying this is what your puppy has, but it sure sounds familiar.  If she has had multiple UTIs, I would think you have an underlying issue of some sort.  Sorry if I'm way off base.

your pups condition sounds very similar to mine. I have not closely monitored her water intake as I have the one gallon bottle that fills the bowl as it gets low. My pup will sit and suck water for long periods and tank up at night but she rarely has problems at night it is usually during the day when she is active and I rarely see her suck alot of water during the day. I will try to monitor her water intake if possible and see what that tells me.

that is an interesting point, I say "I don't believe" its medical because even after being on all those meds nothing ever changed. Both muscle control meds did nothing to change the behavior. she had a UTI/bladder infection combination about 4 months ago.  I said multiple meds because the first 2 didn't work so vet came to believe it was the food causing the urinary problems (hence all the food changes) so with a food change and yet another antibiotic she finally got over the urinary infections. After being on the urinary meds is when the pooping initially started...antibiotics kill good bacteria too i guess...after 2 months of yogurt and no poop accidents I thought the bout with the poop was over until last week when she did it again (might have been my fault) it was after she strained for almost 10 minutes to go that I had her come in the house and as she was running into the living room she stopped hunched up and went almost as if she had no control over it.

I guess I am extremely hopeful that it is not medical also because I have been laid off for almost 6 months and the vet bills just can't keep going gotta feed my family before I can worry about a puppy. I am doing my best to prevail cause I really don't want to give her up but I have to have priorities...

keep the suggestions coming I will try almost anything...cost permitting

Just a thought regarding water intake and keeping her hydrated.  My vet recommends pedialyte ice cubes.  It can slow down the drinking and keep them hydrated. 

Nate-

Besides the peeing, how is her behavior otherwise?  Has she been easy to train and work with in the field?  How does her behavior differ from Dakotas or other GSPs you have been around?  How often does she pee outside when in the field?

To me, it sounds like you and your wife are doing everything right.  I can completely understand how frustrating this must be, especially combined with a layoff.

I guess my questions above stem from the fact that if you chose to rehome her will this even be a solveable issue?  Or...will she just need to be an outside dog exclusively?  There are many dogs that are easy to train, fun to hunt, live very happy/productive lives, but never even set foot inside a house.  Besides a medical condition, it makes no sense to me why she isn't housebroken yet.

My boyfriend was getting frustrated with Koda because is took her until about 7 or 8 months to be trustworthy with the potty training.  He threatened to get rid of her, although he was the one that got her, but I convinced him that you need to stick with the potty schedule, correct accidents, and reinforce the right spot to go.  Hope things start to turn around for you soon. 

Yes!! We all love pictures on this forum. Rocky meeting Schatzi, first GSP pup last summer with GSP Nate and his family last summer.

Schatzi GSP pup looking sweetly up at her Daddy for pup direction. Just adorable sweet puppy face.

It seems interesting that there are not problems at night.
Or, as I read in an earlier post, if you leave her in the crate while you are gone from 7 to 7.
The pee just doesn't leak out, does it? She squats, right?
Oh, both. Hmmmm......

Is your household noisy/exciting/kidchaos while she is active and peeing inside? What if things are calm?

My Bearoff drinks a lot of water and has to pee a lot. Not just a quick squirt on everything, long pees. He doesn't go in the house any more though.   It seems like Bearoff has fast metabolism, hence more peeing. My other dogs don't drink or pee nearly as much as he does. Is she just growing and metabolizing faster than her bladder can handle? Metabolism being slower when sleeping at night, much faster when active during the day.

I do think she will outgrow it but I don't have any better insights than anyone else. I don't think I would spend any more money on vets though. Not unless there is an obvious medical condition. In my experience, vet bills can run up fast while not getting much value for the funds spent. I know it has been happening for a while now and it is very annoying to clean up pee all the time, but I'd just observe and keep working with her. I didn't think Bearoff would ever learn not to go in the house.  If you are unemployed, you probably have more time to spend with her now. I think that makes a big difference for them.

 Good Luck  !!!

Hmmm.....fonts are challenging....
