Dog Scratching Ears And Licking Paws

Watching your dog repeatedly scratch at their ears or obsessively lick their paws can be concerning for any pet owner. While occasional grooming and scratching are normal, persistent or intense behavior often signals an underlying issue. This article explores the most common reasons behind this combination of symptoms, provides practical home care advice, and helps you understand when a trip to the veterinarian is necessary.

Quick Q&A: Common Questions

Question: Why is my dog scratching its ears and licking its paws so much? Answer: This combination of behaviors most often points to allergies, either environmental (pollen, dust mites, mold) or food-related. When a dog experiences an allergic reaction, the paws and ears are common sites of inflammation and itchiness. Secondary yeast or bacterial infections often develop in these areas, worsening the cycle of scratching and licking.

Why Do Dogs Scratch Their Ears and Lick Their Paws?

The underlying cause is typically itchiness, medically known as pruritus. When a dog feels itchy, they naturally scratch, rub, lick, or chew at the affected areas. The ears and paws are particularly vulnerable because they have a rich supply of nerve endings, are often exposed to allergens, and can easily trap moisture.

Allergies: The Most Common Culprit

Allergies are the leading reason dogs develop itchy ears and paws. They generally fall into three categories:

• Environmental allergies (atopy): Triggers such as tree pollen, grass, weed pollen, dust mites, and mold spores can cause seasonal or year-round itchiness. The paws and ears are often the first areas to show signs.
• Food allergies: Some dogs develop adverse reactions to specific proteins (like chicken, beef, or dairy) or carbohydrates in their diet. This can manifest as chronic ear infections and persistent paw licking.
• Contact allergies: Direct exposure to certain materials like carpet cleaners, lawn chemicals, or specific fabrics can irritate the paws.

Ear Infections

Dogs with floppy ears, like Cocker Spaniels or Labrador Retrievers, are especially prone to ear infections. However, any dog can develop one. Signs include head shaking, a foul odor from the ear, redness, discharge, and persistent scratching. Paws may be licked as a secondary response to overall discomfort or because the dog is spreading yeast from infected ears to other areas.

Yeast and Bacterial Infections

When allergies or moisture create an imbalance in the skin's natural defenses, yeast (usually Malassezia) and bacteria (such as Staphylococcus) can overgrow. This leads to intense itchiness, redness, and sometimes a greasy or crusty appearance on the paws and inside the ears. The ears may develop a dark, waxy discharge, while the paws can become red between the toes and have a musty or corn chip smell.

Behavioral or Compulsive Licking

In some cases, the behavior starts due to a physical cause but becomes a habit. Dogs may lick their paws out of boredom, anxiety, or stress. This is more common in dogs left alone for long periods or those with a history of trauma. The constant moisture from licking can then create a secondary infection, making the cycle difficult to break.

What You Can Do at Home

Before you schedule a vet visit, there are safe steps you can take to provide relief and assess the severity of the problem.

Perform a Thorough Check

Gently examine your dog's ears and paws. Look for redness, swelling, discharge, debris, or a bad smell. Check between the toes for any foreign objects like grass seeds or burrs. If you see anything sharp or embedded, do not attempt removal yourself.

Keep the Areas Clean and Dry

• Ears: Use a veterinarian-recommended ear cleaning solution. Apply the solution to a cotton ball (never use a Q-tip) and gently wipe the outer ear canal. Never probe deep into the ear.
• Paws: After walks, wipe your dog's paws with a damp cloth to remove pollen, dirt, or chemicals. Dry them thoroughly, especially between the toes.

Use an Elizabethan Collar (E-Collar)

If your dog is licking or scratching excessively, an e-collar can prevent self-trauma. This allows any minor irritation to heal while you address the underlying cause. It is especially helpful at night when your dog is unsupervised.

Try a Hypoallergenic Diet Trial

If you suspect food allergies, talk to your vet about a strict 8 to 12 week diet trial using a novel protein or hydrolyzed protein food. Avoid all treats, chews, and flavored medications during this period.

What to Expect at the Vet

When you take your dog to the veterinarian for scratching ears and licking paws, the visit typically involves a few key steps to pinpoint the cause.

Physical Examination and History

Your vet will perform a thorough physical exam, focusing on the ears, paws, and skin. They will ask detailed questions about the onset, duration, and seasonality of the symptoms, as well as your dog's diet, environment, and any recent changes.

Diagnostic Tests

• Ear cytology: A sample of ear discharge is examined under a microscope to check for yeast, bacteria, or ear mites.
• Skin cytology: A tape strip or swab is taken from the paw pads or between the toes to identify infection.
• Allergy testing: If allergies are suspected, your vet may recommend blood tests or intradermal skin testing to identify specific triggers.
• Food elimination trial: If food allergy is a possibility, the vet will guide you through a strict diet trial.

Treatment Options

Treatment depends on the diagnosis:

• For infections: Topical or oral antibiotics, antifungals, or medicated wipes and shampoos.
• For allergies: Antihistamines, omega-3 fatty acid supplements, prescription allergy medications (like Apoquel or Cytopoint), or immunotherapy (allergy shots).
• For behavioral licking: Behavioral modification, increased exercise, environmental enrichment, and sometimes anti-anxiety medication.

Prevention Tips

Preventing recurring episodes of ear scratching and paw licking often involves managing underlying allergies or infections.

• Regular ear cleaning: For breeds prone to ear infections, clean ears weekly with a vet-approved solution.
• Paw hygiene: Wipe paws after every walk, especially during high pollen seasons.
• Diet control: Stick to a consistent, high-quality diet that your dog tolerates well.
• Environmental control: Use air purifiers, wash bedding in hot water weekly, and minimize exposure to known allergens.
• Routine vet checkups: Annual exams can catch early signs of allergies or infections before they become severe.

When to Seek Emergency Care

While most cases are not emergencies, you should seek immediate veterinary care if your dog shows any of these signs:

• Severe swelling of the face, ears, or paws
• Difficulty breathing
• Open wounds or bleeding from scratching
• Sudden onset of intense pain or lameness
• Refusal to eat or drink for more than 24 hours

Most cases of scratching ears and licking paws are manageable with proper veterinary guidance and consistent home care. By identifying the root cause early, you can help your dog feel comfortable and happy again.
