How to Tell if Your Dog Has an Ear Infection
Dogs shake their heads occasionally, which is a normal behavior often used to dislodge irritants like water, dirt, or small objects. However, persistent or vigorous head shaking may indicate a deeper issue such as an ear infection.
Common Signs of a Dog Ear Infection
Ear infections are one of the most frequent causes of head shaking in dogs. Symptoms may include:
- Redness and inflammation in or around the ear
- Discharge from the ear canal, often foul-smelling
- Persistent scratching of the ears or rubbing against furniture
- Head tilting or imbalance
- Reluctance to be touched near the head or ears
Types of Ear Infections
There are various types of ear infections, typically caused by:
- Bacterial or yeast overgrowth
- Ear mites—more common in puppies
- Fungal infections
Other Causes of Head Shaking
Though ear infections are the most common reason, other issues may include:
- Allergies—to food or environmental factors like pollen and dust
- Water trapped in ears after swimming or bathing
- Foreign objects such as seeds or debris lodged in the ear canal
- Tumors or growths in or near the ears
- Neurological conditions, including head tremors or vestibular disease
When to See a Veterinarian
Seek veterinary help if you notice:
- Frequent, intense head shaking that lasts more than a day or two
- Swollen, red, or painful ears
- Discharge with a strong odor
- Visible discomfort or mood changes
Untreated ear infections can lead to complications like aural hematomas, where blood vessels in the ear burst, sometimes requiring surgery.
How Vets Diagnose Ear Infections
A thorough physical and otoscopic examination is usually the first step. If necessary, vets may also recommend:
- Food elimination trials to identify allergies
- Skin or blood tests for environmental allergens
- Neurological exams or imaging if a neurological issue is suspected
Treatment Options
- Topical or oral medications for bacterial or yeast infections
- Manual removal of foreign objects—never attempt this at home
- Treatment plans tailored for allergies or structural issues
Always consult with your vet before applying home remedies or over-the-counter products.
Prevention Tips
- Keep ears dry during baths or swimming—use cotton balls as barriers
- Regular ear cleaning with vet-approved solutions
- Promptly address any signs of discomfort to avoid escalation
Head Shakes vs. Head Tremors
It's important to differentiate between voluntary head shaking and involuntary head tremors. Tremors often:
- Occur at rest
- Last less than five minutes
- Are associated with neurological conditions or idiopathic causes
Some breeds like boxers, labs, bulldogs, and spaniels are more susceptible to idiopathic head tremors.
Conclusion
While occasional head shaking is normal, persistent or intense shaking may signal a serious condition like an ear infection. Timely diagnosis and treatment can prevent further complications. Always consult your veterinarian when in doubt.
