Dog
Cold Facts Dogs are the most popular pets worldwide, and their breeds are diverse in their sizes, shapes, and traits. Many of us might have lived with dogs for years, but what we know about their world is only a small part of what they are capable of. The following are some of the surprising and fascinating facts about dogs that you probably have not heard before.
1. Dogs Can Detect Diseases Dogs have a sense of smell that is 100,000 times stronger than humans. This incredible sense enables them to detect diseases such as cancer, diabetes, and epilepsy. Research has shown that dogs can sense changes in our breath, urine, and sweat, and identify the presence of cancer cells. Scientists are now studying dogs to develop new technologies for detecting cancers at early stages.
2. Dogs Can Recognize Emotions It is not a secret that dogs are capable of understanding human emotions. They can sense when their owners are happy, sad, or angry. However, recent studies have shown that dogs can differentiate between happy and angry expressions of human faces. For example, they tend to approach a person with a happy face while avoid the one with an angry one.
3. Dogs See the World in a Different Way Dogs see the world differently from humans. They have fewer color receptors in their eyes, which means they can not distinguish between some colors, such as red and green. However, they have better night vision and can see better in dim light than humans. Also, they have a wider field of vision, which enables them to detect movement from a distance. This is why dogs can detect the presence of animals in the dark that are hard for humans to see.
4. Dogs Experience Dreams Have you ever noticed your dog twitching or moving their paws while sleeping? That is because dogs experience dreams just like humans. Scientists studied dogs' brain activity during sleep and found that they go through similar stages of sleep as humans do. During the REM stage, dogs tend to show physical responses to the dreams they have, such as running or barking.
5. Dogs Have Unique Nose Prints Just like human fingerprints, dogs have unique nose prints that can identify them individually. In fact, some dog breeds are more prone to having nose prints with specific patterns, making them easier to identify. Police and security forces have started using nose prints as a unique form of identification for dogs. In conclusion, dogs are amazing creatures that have many abilities and characteristics that we still do not fully understand. They are not only loyal companions but also can be trained for various tasks, thanks to their exceptional senses and intelligence. It is worth noting that dogs, just like humans, need proper care and attention to live a healthy and happy life.
