Dog Ear Infections: Causes, Symptoms, and Treatment
September 29, 2025

Does your pup scratch their ears constantly, shake their head, or have an unpleasant odor coming from their ears? These are common warning signs of ear problems, which definitely require veterinary attention. At Veterinary Health Center in Saginaw, MI, we regularly treat canine ear infections and guide families on how to prevent them from recurring.

By understanding the causes, recognizing symptoms early, and exploring treatment options, you can protect your canine companion from the discomfort and complications of ear infections.

Common Causes of Dog Ear Infections

Dogs are prone to ear infections for a variety of reasons. Some of the most frequent causes include:

  • Moisture in the ears, especially after swimming or bathing, creating the perfect environment for bacteria and yeast
  • Allergies, which can inflame ear canals and lead to secondary infections
  • Ear mites, microscopic parasites that irritate the ear canal
  • Foreign bodies, like grass seeds or dirt, becoming lodged in the ear
  • Excess wax buildup, which can trap bacteria and debris
  • Underlying conditions, such as hypothyroidism or skin disease, that make infections more likely

Floppy-eared breeds, like Cocker Spaniels or Labradors, are particularly susceptible because less airflow reaches the ear canal.

Symptoms of Dog Ear Infections

Knowing the signs of infection helps owners seek treatment quickly. Common symptoms include:

  • Frequent scratching or pawing at the ear
  • Head shaking or tilting
  • Redness or swelling inside the ear
  • Discharge that may be brown, yellow, or bloody
  • Strong odor coming from the ear canal
  • Crusts or scabs around the outer ear
  • Sensitivity or pain when ears are touched

Severe cases may also cause loss of balance, hearing difficulties, or changes in behavior due to pain.

Diagnosing Ear Infections in Dogs

Veterinary Health Center uses several methods to diagnose canine ear infections:

  • Physical examination, checking for inflammation or discharge
  • Cytology testing, examining ear debris under a microscope for bacteria, yeast, or mites
  • Ear swabs and cultures, when infections are chronic or resistant
  • Underlying condition assessments, to identify allergies or endocrine problems

Accurate diagnosis is key to providing effective treatment.

Treatment Options for Ear Infections

Once diagnosed, treatment often involves:

  • Ear cleaning, to remove debris and discharge
  • Topical medications, such as antibiotic or antifungal drops prescribed by the veterinarian
  • Oral medications, if the infection is severe or recurrent
  • Managing underlying conditions, like allergies, to prevent reinfection
  • Follow-up visits, ensuring the infection is fully resolved

Owners should avoid using home remedies without veterinary guidance, as some can worsen the condition.

Preventing Future Ear Infections

Prevention is as important as treatment. Steps you can take at home include:

  • Dry ears thoroughly after swimming or baths
  • Clean ears regularly with a vet-approved solution
  • Monitor for allergies, as skin and food sensitivities often cause recurrent ear problems
  • Trim excess hair, around the ears if recommended for your breed
  • Schedule routine exams, so veterinarians can catch problems early

Prevention keeps ears healthy and reduces the likelihood of chronic issues. Of course, taking care of those cute ears is just one part of Fido’s beauty regime. Want more insights? Click here for another dog grooming blog.
