Things have just been odd..... until all of the dust settles I'm withholding the breeder name - for now I'll simply disclose they are in Washington and don't refer to themselves as a 'Kennel'.
The 'Kennel' we did work with, on the other hand, is doing great things. They have some unsavory reviews online, but ownership has changed hands in the past couple years (reviews were prior to that) and major changes have taken place there - with facilities, breeding program, and training. That breeder/kennel is Von Walberg Kennels.
We chose one of their prized 'young adults' because his temperament was so similar to our passed 5 year old it wasn't even funny - and I can tell you, that temperament is quite rare.
With that type of personality we should have taken a step back and thought/remembered what the bond was like between my wife and our passed pup. In that situation, my wife got her when the pup was 2 years old but didn't have the interaction/bonding/training that is equivalent to what Von Walberg offers. So when my wife got her, the pup bonded with my wife almost immediately. Even after years of being with her myself, the bond was strong but never what it was with my wife.
We believe the pup we got from Von Walberg had made that 'bond' with one of their trainers. He refused to eat (in 4 days he ate about 1lb of fresh food), didn't make a sound, and after 2 days (though we did our best to entice him, give him praise, attempt to give treats, go on walks, take him with when we went places) he just short of refused to leave one of the dog beds we had set up in our living room (and I was sleeping on the couch next to him during the night).
It unfortunately didn't work out - most of those traits/concerns are trainable or will change with time, but not drinking water and not eating was sort of the big concern.
We took him back on day 5.
While that wasn't fun, when I dropped him off he immediately perked up. After a week we got a follow up that he was "back to his loud rambunctious self" - none of which we saw.
We have decided to wait until 2019 to at least start talking about another pup.
