going on that last ask about working vs show lines, is it worth getting a working line dog if you want to get into dog sports, like tracking, field work, nose work, agility etc. but not actually "work" the dog as part of every day life?

I think this will vary based on the lineage, honestly. Some working dogs are way, way too intense to not work every single day (I’m thinking Czech GSD for example). I think your best bet would be to straight-up ask the breeders, ask people who have previously bought from the breeders, and look into training your dog to settle in the house.

Don’t automatically discount show-line dogs from sports either! Many show-line breeders strive for versatile (but conformationally correct) dogs. Show-line dogs are more likely to have that “off-switch”, but again, it’s probably something you would need to discuss with the breeders and then work on training.
