The dog ear can pick up extremely high sound frequencies

If the way dogs see isn't so good, canine hearing makes up for it. Dogs pick up sounds at a frequency of up to 40,000 Hz - twice that of humans! That's why it's so common to see a dog scared of fireworks, as their sensitive hearing makes the sound even louder. The dog ear is divided into the outer ear (where sound waves start to be picked up and sent), the middle ear (whereis the eardrum) and inner ear (where the cochlea is located, the organ actually responsible for canine hearing and the vestibular system, which controls balance). Dog ear types are varied: there are dogs with large or small ears, erect, semi-erect or drooping and pointed, triangular or rounded. In addition, the dog ear can move in many ways, even being a form of vertical movement.This happens thanks to the 18 muscles present in the area.

The dog's body from the inside has many organs that also exist in the human body. The nervous system controls most of the animal's organs, taking care of sensory, motor, integrative and adaptive functions.
