Wow that guy sounds like a real jerk!! No wonder he still has puppies available lol not to mention, I can’t imagine a show dog would actually be that great of a worker? Nothing against show dogs, I like them, but they’re usually bred for totally different purposes and a lot of working and show line dogs may as well be two separate breeds haha like Labs, GSDs, and most spaniels for example. But maybe they are not there yet. although considering how many people have them for pets nowadays, I wouldn’t be surprised haha anyway, seems like you dodged a bullet with that one.
A lot of LGD show dogs actually are actively working dogs. Not all, but a great deal are. They're bred for confirmation and health, but also to do a specific job, so really you've gotta have the trifecta or what use are they are farm dogs? Great Pyrenees are often poorly bred, so finding a solid, health tested dog that is doing what they're bred to do is like a diamond in the rough, I'm learning.
