Special pets, no? Our Sam was a sweetheart, unless someone went after one of us. Then he’d show his teeth (or more)!
My parents had a male Akita. That breed especially the males can be aggressive around other dogs and strangers. My sister had a poodle that my parents were temporally sitting while they moved. They had to keep the poodle in the basement. When the Akita passed, my parents switched to poodles.
