These Dogs Are Real Life Sherlock Holmes

a dog can detect a spoon of sugar in millions of litters of water or if you can sniff chocolate cookies, a dog can sniff chocolate, eggs, flour and all of the ingredients. This is possible because dogs have a sense of smell 10,000 to 100,000 times better than that of a human, so for 1 human olfactory receptor, a dog has 50. With these receptors, a dog can also notice fear, anxiety and even sadness in humans, because in these situations we secrete a hormone called adrenaline which dogs can detect. Not only in these situations but also if people are dying or grieving, dogs can detect it in a way still unexplainable to humans. So, dogs can sense your emotional state and adapt your emotions to his, your concern becomes his concern as well.
This ability has been used and continues to be used for police and military work, sniffing drugs and bombs, detecting illegal imports at airports, helping find wildlife animals and finding missing persons. It is even said that in a police mission, a dog managed to detect 35 pounds of marijuana immersed in a gas tank. Besides their sense of smell, these dogs are trained to ignore thousands of scents in the air and focus on just one in order to not get distracted and be as effective as possible.
