l canine ear hears sounds, undetectable by humans. The explanation for this theory comes from the following definitions: man between 16,000 and 20,000 captures sound vibrations per second, while the dog receives between 70,000 and 100,000 vibrations.
In turn, the dog's ears have more mobility. Each has seventeen different muscles, and a complex network that enables change of position and locate the source of sound.
The dogs ear functions as a "radar" that stores and classifies different vibration. Some of you are nice and some not so, sounds like too much treble.
Smell: A precision mechanism
The dog has two hundred million olfactory cells. The man just five million. The muzzle of the dog serves as a true precision instrument, which serves to investigate everything perfectly.
In many cases not need to see something or someone to identify or know that it can do so only using your nose. His nose is actually a "database". When you smell something that catches your eye, this place holds in the air for several seconds, record what interests you and stores it. Thanks to the chemical messages (pheromones) that records, you can tell from a distance for example, if another animal in the vicinity is another dog, detecting whether male or female, if a cat or bird, etc.
Touch: An incredible sensitivity
Just born, the dog does not hear nor see, but through touch arrives at his mother's milk and warns that supply heat siblings. The pads are so great sensitivity that can detect even the smallest ground vibration.
Taste: Companion of the smell?
Among the senses of the dog, "taste" is the least investigated. So far it is related to smell. Can preferences for taste or other, depend on the odor that emanates from the object under investigation. If you like the swallows, however if you dislike it rejects.
Vista: A blue and red picture
The view is not the most important sense of the dog. However their distance vision is very good. The dog can get a glimpse movements of 350m, but his view is not nearly as effective.
The eyes of the dogs are farther apart than those of men. This gives a viewing angle of between 250 and 290 degrees, the man does not exceed 210.
Many suppose that the vision is entirely canine black and white. Not so. The eye cells of these animals perceive colors glitter and more or less intense. As the dog has fewer cone cells than men, their vision is limited to blue and red. This disadvantage is offset by the effectiveness of night vision. When it gets dark your pupils dilate more than human, and therefore receive more light.
