Introduction
Canine otitis is one of the most common diseases in dogs of all ages and breeds. It is an inflammation of the ear that can cause pain, itching, and persistent infections, requiring prompt diagnosis and treatment.
What is Canine Otitis?
Canine otitis occurs when dirt, earwax, or microorganisms accumulate in the ear, promoting inflammation of the ear canal. It can be external, middle, or internal, and each form requires a specific approach from the veterinarian.
Main causes
Canine otitis can arise from allergies, moisture after bathing, parasites, entry of foreign bodies, inadequate cleaning, or hereditary predisposition. Breeds with long ears are more vulnerable to humid and warm environments.
Signs that deserve attention
Ear scratching, foul odor, discharge, redness, head shaking, and sensitivity to touch are classic signs of canine otitis . Advanced cases can cause temporary hearing loss and even imbalance.
Genetics and Canine Otitis
Canine otitis can also be related to genetics. Some dogs have allergies, structural defects in the ear, or inherited immune sensitivities, increasing the chance of recurrent inflammation throughout their lives.
