If you think you know absolutely everything about dogs, think again. Are you aware that a dog’s nose is not just odor-sensitive, but so unique and multifunctional that we might even describe it as a built-in minicomputer?
1. Dogs do not originate from wolves
Modern wolves are not ancestors of dogs. Our pets come from a completely different species, extinct thousands of years ago. European wolves are nowadays only very distant relatives of dogs, although their DNA corresponds to 99%.
2. Dogs have a second nose
The second nose of the dog is known as the vomeronasal organ, also called the Jacobson organ. This is a smell receptor that is not really susceptible to the usual smells that people can smell. In other words, dogs have a double nose – sensitive and hypersensitive, located on the border between the oral and nasal cavity.
3. The dog nose has a unique imprint
The print on the dog’s nose is as unique as human fingerprints, and can be used for accurate identification.
4. Dogs sometimes pretend to be sick to receive attention
Owners often say that dogs learn to pretend to be sick or injured to attract more attention. They are wonderful students 🙂
5. Dogs, however, recognize colors
For many years, it was believed that dogs see everything in black and white. In fact, they can see some colors. They distinguish between green, yellow and blue, but they can’t recognize the red color, which they see as dark gray.
6. Dogs can smile
Dogs smile, but not always for the same reasons as we do. They do this to convince their owner to show them affection. But a smile doesn’t always mean that the dog is happy. This may be a sign of nervousness.
7. Dogs sleep with the belly up only in places where they feel safe.
Sleeping with the belly up is common only to dogs that are pets (living at home). This is not surprising, since this is a very defenseless pose. Dogs won’t sleep like this if they don’t feel safe.
8. Dogs don’t feel guilty
Many owners find that a naughty dog feels guilty when he is being blamed for something he had done. Scientists, however, claim that this guilty look is simply a reaction to the gestures and behavior of the owner at this time. The feeling of guilt is a very complex emotion and the dog is simply afraid of being punished. So the pet has learned at some point that if he looks at you with a “I’m sorry” look, this will calm you down.
9. The dog instinctively seeks contact with people
Most of the time, the instincts of the little puppy tell him that the best way to survive is to be close to a person, usually their owner. That’s why a lot of dogs feel very nervous when they are left alone at home. It seems to them that they have been abandoned forever and no one will care for them anymore.
10. People who have dogs sleep better at night
Renting your bedroom to your dog can help you sleep better. However, try not to let him sleep in your bed.
