5 curious things about dogs

5 cosas curiosas de los perros

Dogs are one of the most popular pets around the world. They are loyal, friendly and often become family members. But how much do you really know about dogs? In this article, we'll explore five curious things about dogs that you probably didn't know.


1- Dogs can smell fear

Dogs have an extremely developed sense of smell, allowing them to detect odors that humans cannot. In fact, dogs can detect up to 100,000 times better than humans. But what's even more surprising is that dogs can smell fear in humans. When we are nervous or scared, our body releases pheromones that dogs can detect. So, if you ever feel uncomfortable around a dog, it may be sensing your fear.


2 – Dogs have unique fingerprints

Just like humans, each dog has unique fingerprints. Dog fingerprints are found on the pads of their paws and are so unique that they can be used to identify a particular dog. Unlike humans, however, they are not used in police investigations because dogs' fingerprints can change over time.


3- Dogs can see in black and white

For a long time, it was believed that dogs were completely color blind. However this is not entirely true. Dogs can see some colors, but their color perception is limited. Dogs can see primarily in black and white and in different shades of gray and blue. Therefore, they don't care if their toys are red or green, which means you don't have to spend more money on brightly colored toys for them.


4- Dogs can have nightmares

Just like humans, dogs can also have nightmares. Dogs often have dreams while they sleep, and sometimes these dreams can become frightening. Dogs may move their paws, bark, and whine while they dream, suggesting that they are experiencing a variety of emotions in their dreams. If you ever see your dog having a nightmare, don't worry, it's completely normal.


5- Dogs can feel jealous

Although dogs cannot express themselves verbally, they can feel emotions like humans. A study conducted by the University of California found that dogs can feel jealous when their owner pays attention to another dog. In the study, owners were asked to interact with a stuffed dog while their dog was present. Dogs who observed their owners interacting with the stuffed dog showed signs of jealousy, such as trying to interrupt the interaction or approaching their owner for attention.



Dogs are, without a doubt, fascinating animals. They are one of the oldest species of domesticated animals and have developed a close relationship with humans over the centuries. Dogs are one of the few animal species that can read human emotions and respond to them in a meaningful way. This ability has led many dog ​​owners to consider their pets as members of their family.

In addition to their ability to connect emotionally with humans, dogs also have many other fascinating traits. For example, their sense of smell is one of the most advanced in the animal kingdom. Dogs can detect odors that are imperceptible to humans and can even detect certain types of diseases in people, such as cancer.

Dogs also have impressive physical abilities. They are capable of running at incredible speeds and jumping impressive heights. Some dog breeds also have surprising strength, making them excellent work companions for rescue teams and military forces.

Another fascinating thing about dogs is the diversity of breeds that exist. From Chihuahuas to Great Danes, dogs come in a wide variety of sizes and shapes. Each breed has its own personality and unique abilities, meaning there is a perfect dog for everyone.

In addition to their fascinating nature, dogs also make a great gift for people who love pets. There are a wide variety of pet gifts that can be perfect for dog owners, including personalized collars and toys, dog clothing, and more. These gifts can be a great way to show someone you care about that you appreciate their love of dogs and their fascinating nature.
