Dog Keeps Shaking Head At Night

It can be unsettling when your dog starts vigorously shaking their head just as you're settling down for the night. While an occasional head shake is normal, persistent and repeated shaking, especially at night, signals that something is irritating your dog's ears or head. This behavior is a clear sign of discomfort, and as a responsible pet owner, understanding the cause is the first step toward relief.

Quick Q&A: Common Questions

Question: Why does my dog keep shaking their head at night?

Answer: Nighttime head shaking is usually caused by an underlying irritation that becomes more noticeable when your dog is resting. Common culprits include ear infections, ear mites, allergies, or a foreign object like a grass awn lodged in the ear canal. The quiet environment and lack of daytime distractions make the sensation feel more intense to your dog.

Why Nighttime Head Shaking is Different

Head shaking during the day might go unnoticed or be dismissed as a minor annoyance. However, when it happens at night, it can disrupt both your dog's sleep and your own. More importantly, nighttime head shaking often indicates a condition that has been building throughout the day. The horizontal position and warmth of the bed can increase blood flow to the ears, making inflammation or infection feel more pronounced. Additionally, dogs are less active at night, so they have more time to focus on the irritation.

Common Medical Causes

Ear Infections (Otitis Externa)

This is the most frequent reason for persistent head shaking. Bacteria or yeast overgrowth in the ear canal causes itching, pain, and a feeling of fullness. Dogs with floppy ears, like Cocker Spaniels or Basset Hounds, are especially prone. Signs include a foul odor, redness, discharge, and your dog tilting their head to one side.

Ear Mites

These tiny parasites are highly contagious and cause intense itching. They are most common in puppies but can affect dogs of any age. You might notice a dark, crumbly discharge that looks like coffee grounds. Ear mites are often more active at night, which can trigger increased shaking.

Allergies

Environmental allergies (pollen, dust mites, mold) or food allergies can cause inflammation in the ear canal. This is known as allergic otitis. The ears may look normal on the outside but feel itchy and irritated inside. Dogs with allergies often have other signs like licking their paws or rubbing their face.

Foreign Objects

Grass awns, foxtails, or small seeds can become lodged deep in the ear canal. These objects cause constant irritation and can lead to a secondary infection. If your dog has been outdoors recently, this is a strong possibility, especially if the shaking started suddenly.

Other Causes

Less common causes include polyps or tumors in the ear canal, aural hematomas (blood blisters from shaking), or neurological issues. These are more likely in older dogs or those with a history of ear problems.

What You Can Do at Home

Before heading to the vet, you can take some safe steps to assess the situation and provide comfort.

Visual Inspection: Gently lift your dog's ear flap and look inside with a bright light. Do not insert anything into the ear canal. Look for redness, discharge, swelling, or any visible foreign objects. If you see a grass awn or seed, do not try to remove it yourself, as you may push it deeper.

Clean the Outer Ear: Use a veterinarian-recommended ear cleaning solution. Apply a few drops to a cotton ball and gently wipe the outer part of the ear flap and the visible part of the canal opening. Never use cotton swabs (Q-tips) as they can damage the ear drum or push debris further in.

Provide a Calm Environment: Reduce noise and light in the bedroom. A calming pheromone diffuser or a soft, comfortable bed can help your dog relax and may reduce the perception of irritation.

Monitor for Other Symptoms: Check for head tilting, pawing at the ear, loss of balance, or changes in appetite. These signs indicate a more serious problem requiring prompt veterinary care.

Do Not Use Home Remedies: Avoid putting any oils, vinegar, or over-the-counter drops into your dog's ears without a vet's guidance. These can worsen an infection or cause chemical burns.

When to See the Veterinarian

You should schedule a veterinary visit if the head shaking continues for more than 24 hours, or if you notice any of the following:

• Strong, unpleasant odor from the ear
• Yellow, brown, or bloody discharge
• Swelling or redness of the ear flap
• Your dog is in obvious pain (whining, flinching)
• Head tilt or loss of balance
• The shaking is causing your dog to wake up repeatedly

A veterinarian will perform a thorough ear exam using an otoscope to see deep into the ear canal. They may take a sample of ear discharge to look at under a microscope to identify bacteria, yeast, or mites. In some cases, sedation is needed for a complete exam.

Treatment Options

Treatment depends entirely on the underlying cause. For bacterial or yeast infections, your vet will prescribe medicated ear drops or ointments. These typically need to be applied for 7 to 14 days. For ear mites, a topical antiparasitic treatment is used, often combined with treating other pets in the household.

If allergies are the cause, your vet may recommend antihistamines, a hypoallergenic diet, or allergy testing. Foreign objects usually require removal under sedation or anesthesia. In severe or recurrent cases, surgery may be necessary to correct anatomical issues or remove growths.

Prevention Tips

Preventing nighttime head shaking starts with good ear hygiene and regular check-ups.

• Weekly Ear Checks: After baths or swimming, gently dry your dog's ears with a soft cloth. Check for any signs of redness or discharge.
• Routine Cleaning: Use a vet-approved ear cleaner once a week for dogs prone to ear problems. For others, clean only when needed.
• Manage Allergies: Work with your vet to identify and manage your dog's allergies. This may involve diet changes, supplements, or medication.
• Avoid Irritants: Keep your dog away from fields with tall grass or foxtails. After walks, check their ears, paws, and coat.
• Regular Vet Visits: Annual exams allow your vet to catch early signs of ear disease before they become a nighttime problem.

The Bottom Line

A dog that keeps shaking its head at night is not just being annoying. It is trying to tell you that something is wrong. While occasional shaking may be harmless, persistent nighttime head shaking warrants attention. By understanding the common causes and taking prompt action, you can help your dog get the relief they need and ensure peaceful nights for both of you. When in doubt, always consult your veterinarian for a proper diagnosis and treatment plan.
