A hunk of raw meat and he’ll had them the keys.
There are videos of people that have “guard dogs” in the house. As a test people came in with meat and the dogs walked around with them wagging their tails as they freely went room to room.
My Akitas were the same way. No nonsense, family first, death before dishonor types. Jishin (malek would actively hunt down people & pin them down if he thought that they didn't belong. Little Dog (female) was not like that - she didn't play with her prey.
All that said, never saw either dog make a wrong call, not once in 25 years.
