The following little-known facts about dogs will help you understand them better~
No.1 Dogs were domesticated 9,000 to 15,000 years ago
Over centuries of domestication, humans have domesticated wolves into the various breeds of dogs we know today. Although they differ in appearance, they all retain the social instincts and hierarchical group socialization inherited from their wolf ancestors.
Interestingly, all dogs are "direct descendants" of wolves. This includes the Samoyed, which looks very much like a wolf, and the Pekingese and Chihuahua, which look very different...
No.2 Dogs’ nose prints are unique and similar to human fingerprints
There are many small bumps on the tip of a dog's nose, which are uneven and form the dog's nose patterns.
Zoologists have discovered that the nose prints of each dog are unique, just like human fingerprints.
A Finnish company has developed a dog identifier that uses nose prints rather than microchips.
No.3 The hound can track the scent for up to 300 hours
Humans have 5-6 million olfactory receptors, while dogs have up to 300 million in their noses, which allows them to smell and identify odors at very low concentrations.
They can even distinguish specific scent trails, and a trained hound can follow a scent trail for more than 300 hours, or 130 miles.
No.4 Dogs are not color blind
To be precise, dogs are just a little color blind.
There are only two types of cones on the retina of dogs that are responsible for recognizing colors, while humans have three. These two types of cones allow dogs to perceive short wavelengths (such as blue) and medium and long wavelengths (such as yellow) of light, but they cannot perceive red, orange, and green light like humans.
So dogs can distinguish blue and yellow, but they see red as dark brown and green as grayish white.
No.5 Dogs can hear special electrical sounds
Dogs can hear twice as many frequencies as humans. They can hear sounds from 40 to 60,000 Hz, while humans can only hear sounds from 20 to 20,000 Hz.
During a thunderstorm, they will hear louder and noisier sounds. During a thunderstorm, dogs may also hear the "electrical sound" in the clouds, which is very unpleasant to dogs. Therefore, some dogs hide or become irritable during thunderstorms.
No.6 Fear of heights and digging holes are two natural instincts of dogs
Many dogs become very scared and become motionless when they are picked up. This is because most dogs are afraid of heights and are instinctively afraid of the feeling of having their limbs in the air.
Another instinct of dogs is to dig holes. This is also their survival nature. Doing so can create a cool and slightly humid underground space for dogs in the summer; it is easier to keep warm in the winter; and it can be used to bury leftover food.
No.7 Dogs also dream
Research data based on monitoring of dog brain waves confirms that during sleep, dogs experience brain waves similar to those in humans when they dream, meaning that dogs also dream.
By observing the dog's body movements and facial expressions when dreaming, researchers speculate that most of them dream about playing with their owners. (Of course, they also have nightmares, but the specific content is unknown)
No.8 Dogs can remember at least 200 words
Studies have shown that most dogs only need a little training to understand about 160 to 200 words, and correspond them to "specific actions", "specific behaviors", "objects" and "people". For example, "sit down", "stay", "apple", etc.
In subsequent training, researchers found that some particularly smart dogs (such as border collies) could understand a vocabulary of up to 1,000 words after training, and could also understand and execute complex commands of these word combinations, such as "go to the door and sit down", "find the apple and bring it back", etc.
No.9 Interaction between people and dogs can improve the health of both parties
Research published in Clinical Veterinary Medicine shows that when humans pet dogs, their blood pressure decreases; their heart rate decreases and becomes more stable (helping to prevent potential heart attacks); their muscles relax, and they secrete oxytocin and endorphins, which can effectively relieve anxiety and stress.
Not only that, dogs' blood pressure also drops when they are petted by humans, especially when their heads, which are covered with a large number of touch receptors, are petted, which makes them more relaxed and happy.
No.10 The longest-lived dog lived to 30 years old
Bobi, a Spanish dog, was named the world's oldest dog by the Guinness World Records in 2023. He died at home in October 2023 at the age of 30 years and 266 days.
According to the Guinness Book of World Records, the previous longevity record was held by Australian sheepdog Blue, who lived for 29 years and five months.
The average age of a dog is usually between 10 and 15 years old, but it is affected by many factors, such as breed, body size, living environment, feeding method, nutritional status, etc.
Let us work together to provide them with a good living environment, a proper diet, careful care, and complete medical support, so that the dogs can stay with us longer and longer in good health.
