Types and symptoms of ear diseases in dogs

Inflammation of the external ear or external otitis is manifested by itching, as a result the dog scratches its ears with its paws, rubs it on furniture, rolls on the ground. One of the main diagnostic signs of the disease is the smell of discharge from the ear in the dog, which can be both sugary and sweet, and fetid.

The secretions themselves can be either serous or purulent. This infection can be caused by parasites (ticks), sensitive microorganisms (yeast, bacteria and fungi), foreign bodies. Also, the disease can be triggered by chronic diseases, for example, hyperadrenocorticism, hypothyroidism and others.

The insidiousness of the inflammation of the outer ear is that almost always it passes into a chronic form and, regardless of the medications used, is repeated again and again. Therefore, prevention is very important. Otitis of the inner and middle ear is manifested by more severe symptoms. The dog begins to lose balance when walking, falls, stumbles, or turns in one direction.

Otitis media in the middle ear develops in most cases as a result of penetration through the tympanic membrane from the external ear. If the ear is suppurating it can be a question of the perforation of the tympanic membrane and the danger of the passage of inflammation to the meninges.

Anxiety in the dog is caused by ear mites (Otodectes cyanotis). Tiny parasites are noticeable even to the naked eye. They settle in the external auditory canal and cause not only an itch, but also various inflammations. From the ear also exudates exudate, reminiscent of the color and consistency of dry "ground coffee".
