There are many reasons for the occurrence of otitis media. The main reasons are a violation of the normal state of the external auditory canal as a result of hypothermia, ingress of water or some other foreign objects into the ear canal. Also, otitis media is caused by allergies and parasitic diseases. The video discusses approaches to treating otitis media in order to cure otitis media the first time, rather than heal it. After all, treatment of otitis media without eliminating the cause leads to its constant relapses and turns acute otitis media into a chronic form, with which the dog will have to live for a very long time, if not the rest of its life. When chronic otitis media occurs in the dog's body, many mechanisms are triggered that support the persistence of otitis media.
