What you need to know about dogs – Arzu Candevir

If you are a dog owner, understanding them better and acting on them will strengthen the communication between you. This week, I wanted to share the information I’ve learned on this topic, starting from the basics. Here is some of that information.

Audience: The auricle is moved by 17 muscles. Because of this, dogs may point their earpieces perpendicular to where the sound is coming from. Dogs have the ability to hear higher frequency sounds than humans. The highest hearing capacity in humans is 30,000 fr/sec in childhood, 20,000 in young age and 12,000 fr/sec in old age. In dogs, this figure rises to 35,000-40,000, and even up to 100,000 fr/sec in recent studies in Russia.

Taste: Since dogs do not have many food options in their diet, their sense of taste has remained weak compared to humans, unlike other senses. Dogs’ sense of taste comes from smell and taste, just like humans. Dogs have fewer taste receptors in their mouths than humans. Humans have 9,000 taste buds in the tongue and 1,700 in dogs. Although dogs are carnivores, they have lived under human control for many years. Therefore, there are two types of receptors in the taste buds. They are sugar receptors and amino acid receptors. Sugar-sensitive receptors have the ability to detect sugar molecules in the structure of fruits and some vegetables. This explains why dogs love sweet foods. Amino acid sensitive receptors are more sensitive to specific amino acids such as phosphoric acid, carboxylic acid, nucleotide triphosphate and histidine present in meat and meat products.

Seeing: Full visual function in the eyes begins from six weeks. The fact that the eyes are located forward and on both sides of the head gives dogs a wider viewing angle than humans. The cornea of ​​the eye is larger than a human’s and allows more light to enter the eye, while the pupil opens fully in darkness, providing quality vision even in very low light brightness. Cone cells can see in light, perceive colors and details, rod-shaped cells are dark. He has the ability to see in light and detect movement. In humans, the central part of the retina is made up of cones and the peripheral part is made up of a mixture of rods and cones. In dogs, on the other hand, their ability to see fine detail is weaker than in humans because rod cells and cones are found together in the center of the retina. Therefore, since they cannot perceive the red/orange wavelength in their retinas, they cannot distinguish colors, they can only perceive black, white and gray tones. They can only distinguish certain colors like blue and green under strong light. Dogs perceive the same image better with about three times less light than humans. Therefore, dogs can easily perceive the shape and movement of prey even in the dark at night. Since the dog’s eye is sensitive to the movement of the object rather than the detail, it may not see a stationary living creature at some distance. This can be explained by the fact that the prey remains motionless in its place before escaping at the moment of danger. It has been proven by tests that dogs cannot identify their owners who are motionless at a distance of 300 yards (275 m), whereas a shepherd is noticed by his dog when he waves at a distance of 1 mile (1610m).

Do not touch: The first sense to develop in the early period is the sense of touch. With this sense, puppies show that they react to changes in environmental temperature by seeking and finding the appropriate temperature necessary for their life. Since dogs are social animals, they communicate with other dogs and humans through their sense of touch. This is why the sense of touch is important for dogs. Indeed, human-animal communication studies have reported that light petting and touching causes a decrease in the dog’s heart rate and blood pressure through stimulation of the nervous system, as well as a decrease in heart rate and blood pressure. blood pressure in men. It is also proof that the relationship between man and dog is very positive.

Feel: The sense of smell in dogs is very developed and plays an important role in many behaviors. They often perceive their surroundings with their sense of smell. The sensitivity of smell varies between dog breeds. There are approximately 5 million olfactory receptors in the human nose. In dogs, this number is 125 million cells in the dachshund, 147 in the fox terrier and 220 million in the German greyhound. Moreover, while the area of ​​the olfactory epithelial layers in the nasal cavity is 3-4 cm2 in humans, it is 18-150 cm2 in dogs, and the olfactory center of the brain is about 10 times larger in dogs. than in humans. Add to this the length of the nose, the fact that it is dark and wet, and it is obvious how superior dogs are when it comes to smell and how inadequate humans are.

Other Features: Dogs are social animals with good learning abilities. They can express themselves through body language.

Dogs are sensitive to earthquakes and storms and can sense them in advance.

It has been said that dogs also have senses similar to the sixth sense. They announce earthquakes with howls and storms with bitter barks.

The jaws of dogs are developed in the direction of biting, plucking and chewing, they can bite with a pressure of between 20 and 165 kg with their strong jaws.

Each dog’s urine has its own unique chemical composition. In particular, male dogs have the behavior of marking the areas they roam with their urine, thus informing other individuals that they have established dominance in that area.

By scratching the ground, they leave the smell of sweat glands between their fingers in this place.

The comparisons with people are really surprising and I’m sure you were very surprised while reading it. The nice thing is that you can now understand what your dog’s movements and abilities mean.Ha you know well.

Stay with love on the days with many paws, goodbye…
