We all know that dogs are the best friends of our human race, that they are indispensable in our lives, that guide dogs and rescue dogs and so on, and that they can't do it! And sometimes they're very human, even if they don't teach them, they learn their own skills!
There's one who runs a factory. And for the safety of the factory, there was a dog watcher. And the dog lived here when he was a kid, almost years in a factory doorkeeper. And every day they watch workers work, and dogs learn certain skills, such as the failure of quality tests for the products they produce. Every time the conveyor belt delivers the products, the dog bites to see if they're defective!
I can't believe a dog can become a quality examiner one day. It's a good thing to have a dog, to work as a worker in the daytime, and to keep it as a security guard at night, and to ask someone who can do that? And it doesn't have to be paid, it's enough to feed it every day. The master must treat it well. That's why the dogs are rich.
