Why are my dogs ears so hot? - The Environmental Literacy Council (2025)

A warm, cozy ear might seem like a sign of a happy pup, but what if your dog’s ears are unusually hot? The sensation of hot ears in dogs can be concerning for any pet parent. The reality is that there are several reasons why your dog’s ears might feel warmer than normal. A key takeaway from the information above, hot ears are not always a cause for immediate alarm, but they can indicate an underlying health issue that needs attention. This article explores the common reasons behind this phenomenon, what you should be looking for, and how to respond.

The Primary Culprits: Why Your Dog’s Ears Might Feel Hot

The primary reasons for hot ears in dogs generally fall into three categories: systemic infections, ear canal infections, and inflammation. It’s essential to distinguish between these to determine the best course of action.

Systemic Infection and Fever

Just like humans, dogs can develop fevers as a response to infection. When a dog’s body temperature rises, blood vessels dilate, bringing more blood to the surface, including the ears. This increased blood flow can make the ears feel significantly warmer to the touch. Key signs accompanying a fever could include:

• Red or glassy-looking eyes
• Warm and dry nose
• Shivering
• Panting
• Lethargy or decreased energy
• Loss of appetite

It’s important to note that a dog’s normal body temperature is between 100°F and 103°F, which is higher than humans. If your dog’s temperature exceeds 106°F, it’s considered an emergency and warrants immediate veterinary attention.

Ear Canal Infections

Ear infections, also known as otitis, are another common reason for hot ears in dogs. These infections can be caused by bacteria, yeast, or ear mites. Ear infections often lead to significant inflammation within the ear canal, triggering a localized increase in temperature, making the ear feel hot to the touch. Be on the lookout for these signs of an ear infection:

• Scratching at the affected ear or face
• Head shaking, ear rubbing, or tilting of the head
• Redness or swelling in the ear canal or pinnae (the visible part of the ear)
• Crusting or scabs
• Abundant ear wax
• Purulent discharge or pus of any color
• Unpleasant odor

If you notice these symptoms alongside hot ears, an ear infection is highly likely.

Other Causes of Inflammation and Sensitivity

Beyond infections, other factors can cause inflammation and increased heat in a dog’s ears. These include allergies (including food allergies), which can lead to skin irritation and inflammation, and the presence of ear mites. Tiny bugs called ear mites can cause considerable irritation within the ear canal, leading to itching and heat. Also, while not as common, certain breeds might be more sensitive to environmental changes or have skin conditions that may predispose them to hot ears.

How To Respond to Hot Dog Ears

When you realize your dog has hot ears, it’s essential to assess the situation calmly and take the right steps.

Check for other Symptoms

Before making assumptions, check for other symptoms that may give clues as to the underlying issue. Does your dog have other signs of illness like fever or lethargy? Is there redness, discharge, or an unusual odor coming from the ears? Noting any additional symptoms will help you determine the severity of the problem and what type of care your dog may need.

Monitor Temperature

If you suspect a fever, the most reliable method of determining if your dog has a fever is by taking their temperature, preferably rectally using a pet-safe thermometer. While ear thermometers can be used, they can be less accurate and are generally more expensive than rectal thermometers. A normal temperature for a dog ranges from 100°F to 103°F. If their temperature is over 106°F, it’s considered an emergency and requires immediate veterinary care.

Home Care Options

If the hot ears are not accompanied by severe symptoms or high fever, there are some things you can do at home for relief:

• Cool Compress: Apply a cool, damp cloth to your dog’s ears to help alleviate heat and discomfort. This will also help relax the dog.
• Olive Oil: In the case of irritation or suspected ear mites, a few drops of warmed olive oil can be gently massaged into the ear canal to soothe and potentially help float debris out of the ear.
• Avoid Human Medications: Never give your dog human medication or fever reducers, as they can be dangerous for them.

When to Consult a Veterinarian

If your dog exhibits the following symptoms alongside hot ears, it’s crucial to see a veterinarian:

• High Fever (above 103°F or 106°F)
• Severe pain
• Significant discharge or odor from the ear
• Persistent head shaking or scratching
• Loss of balance or disorientation

Prompt veterinary care is essential to diagnose the underlying cause of the hot ears and to prevent potential complications, such as hearing loss, chronic ear infections, or, in severe cases, more serious systemic issues.

Frequently Asked Questions (FAQs) About Hot Ears in Dogs

Here are 15 common questions pet parents have about hot ears in dogs, alongside detailed answers to provide a comprehensive understanding:

1. Are warm ears always a sign of a problem in dogs?

Not always. It’s natural for a dog’s ears to feel warm, as they have a good supply of blood vessels. However, unusually hot ears or ears that are warmer than the rest of their body may signal an underlying issue.

2. Can allergies cause hot ears in dogs?

Yes, allergies are a common cause. Both food and environmental allergies can cause skin inflammation, leading to hot and itchy ears.

3. How can I tell if my dog has a fever by touch?

It’s difficult to tell by touch. Although a warm nose is a common myth, the most reliable way to check for a fever is by taking your dog’s temperature with a thermometer.

4. Can ear infections in dogs go away on their own?

No, ear infections in dogs typically do not resolve without treatment. Left untreated, they can lead to more severe issues, including hearing loss.

5. Can I use human ear infection remedies on my dog?

No, you should never use human ear medications on your dog without explicit instructions from your veterinarian. These medications may not be effective and could even be harmful.

6. What can I put in my dog’s ears to clean them?

Hydrogen peroxide (diluted) or an ear-cleaning solution specifically formulated for dogs can be used to clean the ears. However, always follow veterinary guidance and do not use if the ear tissue is raw.

7. How often should I clean my dog’s ears?

Cleaning frequency depends on your dog’s breed, ear type, and susceptibility to infections. Generally, a weekly check and cleaning (as needed) may suffice. Discuss an appropriate cleaning regimen with your vet.

8. Is olive oil safe to put in my dog’s ears?

Yes, warm olive oil can be a safe and soothing home remedy for minor irritations, and it can help soften and remove debris. However, it won’t cure a true infection.

9. Can apple cider vinegar help with ear infections?

Diluted apple cider vinegar can help with mild yeast or bacterial infections by creating a hostile environment for pathogens. However, do not use if ear tissue is raw or broken, and consult with your veterinarian.

10. What is “Red Ear Syndrome” in dogs?

Red Ear Syndrome is a rare clinical entity that involves episodic erythema (redness) and burning sensations or pain in one or both ears. While it is more commonly associated with humans, similar symptoms could arise in dogs, and should be reviewed with a veterinarian to rule out other conditions.

11. Why is my dog shaking his head a lot?

Head shaking is a common symptom of ear irritation and infections. If your dog is shaking his head often or excessively, it could indicate an ear problem.

12. Should I be concerned if my dog’s ears are red?

Redness, especially alongside heat, could be a sign of inflammation or infection. It’s best to get a vet to rule out any serious issues.

13. Can I use Benadryl for my dog’s ear infection?

Benadryl (diphenhydramine) can help relieve itching and inflammation associated with allergies. However, it does not treat the underlying infection.

14. How do I know if my dog’s ear infection is bacterial or fungal?

A veterinarian needs to take a sample from your dog’s ear and analyze it under a microscope to identify the exact cause. This will determine the best course of treatment.

15. How soon should I take my dog to the vet for an ear infection?

Ideally, you should see a vet as soon as you suspect an ear infection. Early intervention can prevent complications and ensure a quicker recovery for your dog.

By understanding the causes of hot ears and taking a proactive approach, you can help keep your canine companion happy and healthy. Always consult your veterinarian if you are concerned about any symptoms.
