I could not agree more with what ShadowBuck just posted.
They need to be able to run free in the house once trained and they need to go places with you and be part of the family and exercised like Shadow mentioned, and if you will do that, you will end up with about as mild mannered dog as one could have.
Neither one of our dogs have ever dug in the yard, but once I get them out where they smell mice, squirrels, etc, my female is a digging machine and Oxford digs too, but not like Lexi.
We have a doggie door in our house and they come and go as they please into the fenced backyard. Never once have they tried to escape over the wall or fence which in one section is only 3 feet high.
Oxford loves the water, Lexi is just opposite.
When I am gone hunting, the wife works and walks the dogs before she goes to work, and the rest of day they just sleep in the house and full roam. Never once had they destroyed anything once they left the puppy stage. But when Oxford was a pup I lost a number of my favorite hats to his teeth, along with a few pair of shoes. But now we trust them unequivocally.
I don't know a lot about dogs in general, but I do think I know a lot about Weimaraners and if you ever want to call or PM on anything, feel free to do so.
Here's the digging machine at work. I have often told the wife I can't believe Lexi doesn't dig at home.
I would sure like to see some photos of you new pup. There's not many puppies cuter than this breeds, blue eyed pups.
Have a good one. BB
