I’d generally agree, but OTOH my aunt has had and bred farm BCs for decades. She has let her children and nephews take those puppies and they have not had much trouble with them in normal suburban life.
I’m still a GS person and still never forget how my long-gone dog outsmarted her BCs in their own house!
GSs are great dogs, too, and smart. All the herding breeds have to have some smarts to do what they do. GSs make good guard dogs as well, which BCs, generally, do not. BCs are a little small to excel at that, a bit too curious, and well aware of their limitations. They do make great watch dogs, however, as their senses are exceedingly keen.
