Yes the experienced owners I know ( they used to have lovely rescues - GSD,s sometimes three at once in the extended family- None were ever a problem.
Due to arthritis they can’t manage GSD’s any more, so got a Romanian dog 5 yrs ago that they were told the usual huff about
“Good with people, good with other dogs, good at maths- Made him sound an easy dog.
He’s infinitely worse than they were told- seems the “ Good with” is just a party line that people are told.
Had this family not been so experienced with big shepherd guarding types, they’d have been on over their heads-
When they see me and my well behaved quiet dog approaching, they ask if we can cross the roads
We do, but the dog still lunges and is strong, despite being much smaller than their past GSD’s
A Kangal belonging to someone else ( imported) bit a woman’s hand very badly after they were told it would be ok.
That was returned as aggressive.
These are dogs that would probably be far happier living outside -
Having said that- Macau Canidrome greyhounds were shipped to U.K. and after assessments those appear to have settled very well into homes ( although some were Irish or Australian reared dogs) so at least had daily dealings with people to socialise them a bit.
A lot had very expensive dental issues and cancers though, but were / are sweet natured dogs.
