Do you know about the world in a dog’s dreams?

Through the observation of brain waves, it has been discovered that dogs, like us, also enter into deep sleep phases. During this time, there are rapid eye movements and changes in breathing, much like when we dream. You may notice that dogs start to move their paws and even make some strange sounds during this time, which is actually their way of sleepwalking!

For many new pet owners, seeing their dogs shake or twitch their bodies while sleeping may cause concern, leading to worries about seizures and rushing to seek medical help. However, these movements are often just signs of dogs being deeply asleep and feeling quite comfortable.

These movements that deeply sleeping dogs make are often related to their activities during the day. It’s like the concept of “daydreaming at night.” These movements may be because dogs are re-experiencing their adventures from the day, such as chasing balls or playing with other dogs. So, when you see your dog exhibiting such behaviors during deep sleep, you can rest assured that it’s likely just a manifestation of pleasant memories deep in their minds, showing trust and a sense of security towards their family and environment.

☑️ Paw Shaking

When you see a dog’s paws shaking or moving back and forth, it’s very likely that they’re dreaming about walking or going for a stroll.

☑️ Eye Rolling

If a dog’s eyes are rolling during sleep, it’s very likely because they’re dreaming about their beloved owner or anticipating a delicious treat in front of them.

☑️ Tongue Protrusion or Mouth Closure

When a dog’s tongue is slightly protruding or its mouth is closed during sleep, it’s very likely because they’re dreaming about enjoying delicious food.

In fact, dogs are indeed color blind, but that doesn’t mean they can’t play important roles, such as guide dogs. How do they navigate between red and green lights to guide visually impaired individuals?

The visual system of dogs differs from humans. They primarily perceive shades of gray and yellow-blue colors, with little sensitivity to red and green hues, due to fewer types of cone cells in their retinas compared to humans. While this deficiency in color perception exists, dogs excel in low-light vision, making them see clearer in the dark, which is one reason why they navigate better at night.

Despite being color blind, guide dogs are still able to discern between red and green lights at busy intersections, thanks to their specialized training that cultivates exceptional intuition and reaction time. During training, they learn to recognize the shape, brightness, and position of traffic signals, ensuring visually impaired individuals can safely cross the road.

French Bulldogs, these little companions, have always been beloved for their unique characteristics. Now, let’s take a look at the four key traits of these adorable dogs:

1. Suitable for urban livin

The French Bulldog is considered one of the most human-friendly dog breeds. Despite their slower pace, they typically exhibit friendly and gentle traits when interacting with other dogs, avoiding attempts to assert dominance. It’s worth noting that they have relatively low exercise needs, requiring less time for walks, making them an ideal choice for people living in urban areas.

2. Highly sensitive personality

Although they may appear a bit goofy, never mistake them for being unintelligent. If you shout at them or scold them loudly, they can feel extremely disheartened. In fact, research indicates that about 80% of French Bulldogs are highly sensitive to their owners’ language. Positive expressions of praise and encouragement contribute to their overall health and happiness.

3. Long-distance travel is a challenge

Many airlines refuse to transport French Bulldogs due to their short noses, which can lead to various respiratory issues during flights. Additionally, the combination of high-altitude pressure and unsuitable temperatures poses challenges for this breed; hence, they are declined for transportation.

4. Expressing emotions in a gentle manner

French Bulldogs express emotions in a rather quiet manner. Unlike other dogs that release emotions through barking, they tend to prefer behaviors such as gazing, drooling, and yawning to communicate their needs. Additionally, French Bulldogs are considered somewhat homebodies, with relatively low exercise requirements.

Why do Chihuahuas always love to bark? Actually, there are reasons behind it!

1. Related to Brain Structure

Due to their extremely small size, their brains are relatively petite. This compact size results in higher cranial pressure, causing some physiological stress and making their emotions more sensitive.

2. Want to Drive Away Threats

Naturally alert, they are particularly sensitive to subtle sounds in their surroundings. When they sense anything unusual, they start barking. Even though their aggressiveness is limited, they hope to deter threats through barking.

3. Emotional Insecurity

Typically of a timid nature, this leads to a lack of emotional security, causing them to become sensitive and nervous. This insecurity can result in some intense behaviors, such as excessive barking.

4. Health Issues

Compared to other dogs, their bodies are relatively fragile, making them more susceptible to illnesses. When they feel unwell, they seek assistance from their owners and express this need through barking.

Cats possess agile movements and move silently, making them seem like potential spy candidates. Could they really be used as cat spies?

In the 1960s during the Cold War between the United States and the Soviet Union, the U.S. attempted to train cats as spies to gather intelligence from the Soviet Union. They implanted batteries and transmitters in the cats’ bodies and placed listening devices in their ears. After a series of training sessions, the hope was that these cats could eavesdrop on conversations in settings like meetings or restaurants.

Throughout the entire “spy cat” program, the United States spent five years and a total of 13 million dollars on research. During the research, they discovered that the biggest challenge was that the cats might leave their mission due to hunger, resulting in the recorded sounds being irrelevant. To address this issue, they even performed surgeries on the cats to reduce their hunger.

Unfortunately, the first official mission ended in tragedy when a taxi hit one of the cats, leading to the failure of the entire program. Ultimately, the United States abandoned the project, keeping it classified until it was declassified in 2001.
