People hide genetics in American lines too. How do you think I got my blue dog from an American showline bitch? Can't target imports for that.It’s more the fact that people hide that the genes are there by hard culling the off colors. It’s one thing to know that the line carries it, it’s another to hide it like it’s a dirty secret. Off color pups I see no issues with just soft culling them to pet homes. Unless dogs are a total train wreck they should easily be able to be soft culled to pet homes if they aren’t breeding worthy.
There are countries other than Germany that dogs can be imported from, and still be from overseas, not everything imported from overseas even WGSL is going to be health tested and titled. And there’s a difference between an adult cull getting sold because they can’t breed it in Germany vs. getting a puppy from a good litter just not getting the arbitrary “best” puppy unless the puppy received has health/temperament issues. My dogs with drive are a lot easier to exercise than Shelby, and a lot more fun. They’re fine with a hike or I can do specific activities we both enjoy. You can have a mellow easy going dog and have drive, they aren’t seperate entities that can‘t co-exist. A dog with no off switch that can’t settle can happen in low drive or higher drive dogs. Our previous ASL GSD was an amazing dog. Healthy until the end with what I think was DM and died of bloat. He was easy going, great with other dogs, people, kids. He had higher drive and less energy than Shelby. A much more settled, confident, and well rounded dog temperament wise. His biggest flaw was head butts to the nose when giving him attention.
Edit/add on: I do think there is a huge genetic component but I wonder how much the fear issues and other problems have been exacerbated by early altering in the US.
OP is looking to purchase a pup. Simpler to stay on topic by discussing puppies and their parentage. You are taking this topic all over the place. We can't discuss all possibilities.
I disagree that a dog with high or strong drives being naturally mellow. That doesn't mean that high drive don't have an off switch or can't be good pets. There are other traits that interplay with drives but low drive is usually associated with soft, often mellow, dogs.
You absolutely can take a low drive, high energy dog on long hikes. I even prefer them because they are easy and I don't have to monitor them constantly. My showline will go all day. If I can't exercise him, he is always up to a good romp with one of my other dogs or at the dog park. Like I said before, low drive dogs are easy keepers.
