Dog knows

The police in Dicos Town have high professionalism, so the town's security is very good. Among these police officers, McGray is the best. Usually, McGray always looks careless, but he can tell who the thief is just by looking into the street. This stunt is very envious of young police officers.

　　On this day, McGray was wearing a police uniform and smoking a pipe, walking leisurely on the street. Not far away, the door of a villa was suddenly opened, and a man came out.

　　The man was dressed in a suit and leather shoes, his hair was meticulous, and the leather shoes on his feet were spotlessly polished. Despite this, McGray always felt that something was wrong. McGray deliberately looked at the leather bag that the man was holding under his arm. The bag was so stuffed that the fine leather bag lost its original shape.

　　McGrey strode forward and said, "Sir, please stay!"

　　Everyone would be startled when such a sturdy police officer suddenly rushed in front of him. This gentleman was no exception. He took a few steps back, looked at McGrey with puzzled and resisting eyes, and asked, "Mr. Police, what's the matter with you?"

　　McGray took out his police card, shook it in front of the man in the suit, and said bluntly, "Did you just steal something?"

　　The question was so direct that Mr. Suit froze for a moment and couldn't help laughing. He tried to calm himself down and said to McGray, "Mr. Police, please consider what you just said."

　　McGray replied: "Of course I know, my judgment is very accurate, and I can't be wrong."

　　Mr. Suit looked extremely impatient and said, "The police need evidence to handle a case. If you frame a good person, I can sue you!"

　　McGray ignored Mr. Suit's attitude, still holding his pipe and asking, "Tell me, why are you sneaking around?"

　　"Humph!" Mr. Suit sneered, "Am I being sneaky or are you nervous?" After speaking, he didn't look at McGray, and strode forward, intending to leave here.

　　After several exchanges of words, Mr. Suit has always been righteous, which made McGray a little suspicious of his own judgment. McGray looked at the window of the villa. When he questioned Mr. Suit just now, no one came out of the room, indicating that the villa was empty. And this Mr. Suit doesn't look like the owner of this villa. If he was let go like this, wouldn't it be possible to let a criminal go?

　　McGrey took a big step in front of Mr. Suit, blocked his way, and said politely, "Sir, please come with me to the police station!"

　　Infuriated by McGray's request, Mr. Suit pointed to the door of the villa and said, "I'm the owner here! Do you suspect me of stealing my own stuff?"

　　McGrey said uncompromisingly, "Then how can you prove that you are the master and not the thief?"

　　Mr. Suit was suddenly stumped by McGray's question, apparently he was not at all prepared to prove his identity to others. Just when he was in trouble, a long-haired dog suddenly ran out of the villa. It came straight to Mr. Suit, circled him, and sniffed his hands affectionately.

　　The dog's performance gave Mr. Suit confidence all of a sudden. He touched the dog's head affectionately, and then looked at McGray with a little pride.

　　Seeing this scene, McGray began to believe Mr. Suit's words. Obviously, Mr. Suit is very familiar with dogs and cannot be a thief. McGray could only say: "I'm sorry, it seems that I really suspected wrong."

　　McGray was about to let Mr. Suit leave when the long-haired dog suddenly barked "woof". Mr. Suit glanced at McGray and shouted to the big dog, "Mary! Don't bark!"

　　The long-haired dog named Mary heard Mr. Suit's scolding, and suddenly stopped making a sound. It ran under the telephone pole on the side of the road, raised one leg, and urinated. McGray watched the long-haired dog finish urinating and crouched down beside Mr. Suit obediently.

　　Mr. Suit watched the long-haired dog do all this with satisfaction. He held McGray's outstretched hand and planned to say goodbye to him. But the word "goodbye" suddenly retracted from McGray's mouth. He watched the long-haired dog pee thoughtfully.

　　Suddenly, McGray took Mr. Suit and twisted his hand behind his back. Mr. Suit shouted angrily: "Hey! What do you want to do?"

　　McGrey smiled and said, "Sir, stop pretending, you are a thief!"

Mr. Suit was taken to the police station, and he kept yelling in disbelief, claiming that McGray had wronged him and wasted his precious time. McGray, on the other hand, sat there calmly, letting him make trouble. McGray finished smoking a cigarette, sat at the table and asked Mr. Suit, "Do you want to know why I'm arresting you? It's up to you to call that long-haired dog Mary!"

　　The man in the suit said dismissively: "Is it against the law for me to name my dog?"

　　McGrey shook his head and said, "Of course it's not illegal, but you're lying! Please tell me, is that dog male or female?"

　　This time, Mr. Suit was stunned for a moment. He seemed to be trying to remember, and hesitated: "It is... it is..."

　　McGray continued: "You don't even know the gender of your dog, do you? How dare you say it's your dog?"

　　Mr. Suit calmed down for a moment and said in a gamble: "Of course I know, it's a bitch, otherwise why would I name it Mary?"

　　McGray said, "Okay! Then let me ask you, what's the difference between a male dog and a female dog when they pee?"

　　Mr. Suit didn't know what McGray meant, and was still hesitant to speak. McGray stood up and walked around Mr. Suit before saying with a smile: "When a male dog urinates, it raises one leg and spreads it, but a female dog is different. Even a three-year-old child knows. Now, do you remember how that dog urinated?"

　　Sweat seeped from Mr. Suit's forehead, and he began to understand what McGray meant by asking. When the long-haired dog was urinating, it did raise its hind legs and spread them out, so it was a male dog.

　　"It was the dog who exposed your lies. Didn't you think of this?" McGray said while laughing, "That dog is a long-haired breed, so it is difficult to distinguish between males and females in appearance. But when it pees The movements that appear at the time indicate that it is a male dog. But who would name a male dog Mary? How can a dog owner not know the gender of his dog?"

　　There was a lot of cold sweat on Mr. Suit's head, but he still looked up and asked McGray: "Then how do you explain that dog is so close to me? It revolves around me like it welcomes its owner! Could it be so close to a thief?"

　　This question was difficult for McGray. He thought about it and said, "The answer is very simple. When you entered the house, you must have fed it meat slices or something, that's why it was so affectionate to you. Dogs are beasts after all."

　　Mr. Suit's psychological defenses finally collapse, and he admits he's a thief.
