What is Dog Ear Infections?

Whining, scratching, and head shaking are often the first symptoms of Dog Ear Infections, it is a common condition in dogs that can affect one or both ears and is especially common to a dog who has floppy ears such as Spaniels. Most ear infections in adults are caused by bacteria and yeast, though ear mites are a common cause in puppies. You may also notice an abnormal odor from the ear or see redness or swelling.

  • Otitis Media – Which is an inflammation of the dog’s middle ear. 
  • Otitis Interna – Which is inflammation of the inner ear.

Otitis Media and Otitis Interna can be very serious and may result in deafness, facial paralysis, and vestibular signs. It is recommended to see your dog Vet for early treatment when the symptoms show to prevent it to happen.
