Knowledge of Dogs

In the story "In Trouble" the author said "they had great, old knowledge; they had something we had lost". To me, it means that dogs have skills and knowledge that we don't have. For example, dogs are great at hearing and smelling, we can't do that. Dogs can also tell wether foods are edible or poisonous, which we can't. They are born to do these tasks. Some dogs are trained to do special tasks such as guard dogs. They are trained to tell wether a person is or is not a person that they wanted. Dogs in airports, they are trained to tell wether a person's luggage has things that shouldn't be carried. People can sometimes learn from dogs, such as how they act. When you are nice to a dog, it will be nice to you because of what you did to him. Basically, dogs followed the golden rule every time. Which is treat a person the way you wanted them to treat you. For example, if you give a dog a piece of cookie, or you petted him today. He might come back to you and starting to play with you because he liked you because of what you did.
