The external ear The external ear includes the auricle and the external canal, which are sound receivers; the auricle and the canal together form the ear, which is covered externally with fur and is formed by the vertical ear cartilage. The microenvironment of the external ear canal: pH 6.1, temperature 38.2°C, humidity about 80%, the presence of a small number of microorganisms, once inflammation occurs, it means that the environment changes and becomes a suitable breeding ground for microorganisms to multiply. At the same time the ear canal is prone to accumulation of grease, dust and moisture, especially in large-eared dogs, where the drooping ear shell often covers the ear canal, or the long hair near the ear canal can also cover the ear canal, so that the ear canal is prone to accumulation of dirt and moisture due to poor air circulation and inflammation of the ear canal.
Middle Ear The middle ear consists of the eardrum, tympanic chamber and auditory tube, which converts sound waves into mechanical vibrations.
The inner ear consists of the auditory and balance organs that convert mechanical vibrations into electrical impulses that can be recognized by the central system of the brain.
