Ear Infection In Dogs

Ear infections in dogs are an inflammatory disease acute or chronic, affecting the ear, the ear canal, and the eardrum. L ‘ ear inflammation is widespread in dogs and is caused by various types of pathogens such as parasites (the most common is a mite, Otodectes the cyanosis), and fungi. In this article, we will give you a complete guide about Ear Infection In Dogs.

It can also develop due to foreign bodies, allergies, keratinization disorders, endocrine disorders, glandular disorders, autoimmune diseases, viral diseases, and cancers. This article gives you full-on information about ear infections in dogs.

How is the dog’s ear formed?

The dog’s ear can be divided into three main sections:

  • Outer ear: This area consists of the auricle and the tube-shaped ear canal.
  • Middle ear: starts from the eardrum (also called the tympanic membrane), a fragile membrane that can easily injure itself and cause serious diseases of the dog’s ear. The middle ear comprises three small bones (ossicles) called: hammer, anvil, and stirrup.
  • Inner ear: houses the nerves that send sounds to the brain and help the dog stay balanced.

Ear inflammation in dogs: the causes

Some of the pathogens that can live and grow inside an infected ear, aggravating the inflammatory process, are mainly yeasts ( Malassezia pachydermatis) and bacteria (Staphylococcus sp, Pseudomonas sp, Proteus sp, and E. coli). In dogs, the disease can be difficult to treat because one must first identify the type of organism causing the inflammation before starting treatment. A good diagnosis is also important to treat the disease and prevent recurrent ear infections in dogs.

If neglected, dogs’ ear infections worsen, reaching the middle ear ( otitis media ) and becoming more difficult to treat. Ear inflammation in dogs causes discomfort, itching, and pain. The dog often bends down and shake his head, scratch himself to cause lesions in the areas near the ear, cry, moan, and even bite you. Generally, you may notice foul-smelling pus or earwax coming out of the ear.

Predisposing factors

These factors make dogs more prone to inflammation and infection of the outer ear. If the ear canal is closed or too narrow, it can allow secretions and ear wax to build up, promoting infections.


  • Parasites like ticks, fleas, and other mites are among the leading causes of dogs’ ear problems.
  • Allergies: Dogs with food or skin allergies can develop ear infection in dogs
  • Foreign bodies such as small branches or small stones get stuck in the dog’s ear canal.
  • Polyps and tumors
  • Hormonal Disorders: Various hormonal problems (such as hypothyroidism and hyperthyroidism ) can cause skin and ear problems.
  • Genetic and hereditary diseases
