Keeping Your Dog’s Ears Healthy: Types Signs Causes Treatment and Prevention

Who doesn’t love dogs? They are loyal companions that brighten our days.

While we love them unconditionally, it is also our responsibility to keep them healthy. One of the common health issues among dogs is ear infections.

In this article, we will explore the types of dog ear infections, signs, causes, treatment, and prevention. Additionally, we will also discuss the unique anatomy of dog ears and compare them to human ears.

Types of Dog Ear Infections:

The ear infections in dogs can happen in the outer, middle, or inner ear. Outer ear infections are known as otitis externa.

When the infection affects the middle ear, it is called otitis media, and when it affects the inner ear, it is known as otitis interna. Otitis externa is the most common type, which affects the ear canal’s lining.

However, if left untreated, the infection can spread to the middle and inner ear, leading to severe consequences. Signs of Dog Ear Infections:

The signs of an ear infection in dogs can vary depending on the type and severity of the infection.

Some common signs include redness, odor, itching/scratching, pain, shaking of the head, head tilt, and discharge from the ear. Some dogs may also become unresponsive or lose their balance in severe cases.

Causes of Ear Infections in Dogs and Puppies:

There are various reasons behind ear infections in dogs and puppies. Some of the common causes include foreign bodies, ear mites, excessive moisture, food allergies, environmental allergies, endocrine issues, autoimmune diseases, polyps, cancer, or trauma.

Treatment for Dog Ear Infections:

The treatment for dog ear infections depends on the type and severity of the infection. Usually, the vet will prescribe topical medication such as ear drops or ointments, along with antibiotics or anti-inflammatory medications.

For severe cases, surgery may be required to treat the infection and prevent further complications. Prevention of Ear Infections in Dogs and Puppies:

Prevention is always better than cure, and there are several steps you can take to prevent ear infections in dogs and puppies.

Regular grooming is essential, which includes brushing their fur, trimming the hair around their ears, and cleaning their ears. Use ear cleaning solutions specifically designed for dogs and avoid using Q-tips.

Always dry your dog’s ears after swimming or bathing to prevent excessive moisture buildup. Anatomy of Dog Ear:

Dog ears are unique compared to humans, with a distinct long ear canal that has vertical and horizontal components that resemble a J or L shape.

This anatomic structure makes their ears prone to debris buildup, leading to ear infections. Additionally, dog ears are more sensitive to sound, which allows them to hear frequencies up to 65,000 Hz, while humans can only hear up to 23,000 Hz.

Comparison to Human Ear:

The anatomy of the human ear is different from dog ears.

Humans have a shorter ear canal that leads to the inner ear, which contains the eardrum, ossicles, and cochlea. Unlike dogs, humans have better control over the muscles in their ears, allowing them to move their ears voluntarily.


In conclusion, ear infections in dogs are a common problem that can lead to severe consequences if left untreated. As responsible pet owners, it is our responsibility to keep our furry friends healthy and happy by taking preventive measures and seeking veterinary care when necessary.

By following the steps mentioned above, we can ensure that our dogs’ ears remain healthy and free from infections. Contagiousness and Home Treatment:

Ear infections in dogs can be caused by different factors, including ear mites.

Ear mites can be highly contagious, and they spread from dog to dog during close contact or through sharing of bedding, toys, or grooming supplies. Therefore, it is essential to ensure good hand hygiene to prevent the spread of ear mites.

While ear infections can be unpleasant and uncomfortable for dogs, it is not recommended to treat the infection at home. Home remedies such as over-the-counter treatments for ear infections may be ineffective, cause further damage, or make the situation worse.

Many home treatments which may seem like common sense cures can, in fact, cause further damage to the ear canal and increase the dog’s pain, making it important to seek veterinary care instead. Veterinarian Evaluation and Importance of Testing:

A veterinarian should always evaluate a dog with an ear infection.

After conducting a thorough physical examination, the veterinarian may recommend additional testing, including cytology, culture/sensitivity testing, blood testing, or scans. Cytology is performed by taking a sample of discharge or material from the ear canal and examining it under a microscope, helping to determine the type of infection present and appropriate treatment.

Culture/sensitivity testing is used to determine the type of bacteria present and which antibiotics are effective in treating the infection. Blood testing and scans may be used to identify underlying medical conditions that may predispose a dog to ear infections.

Chronic Ear Infections:

Chronic ear infections in dogs can be frustrating and time-consuming for both the dog and owner. Dogs who suffer from chronic ear infections may require multiple visits to the veterinarian, different treatments, and long-term medication to manage the condition.

It is important to note that certain breeds such as Cocker Spaniels, Labrador Retrievers, and Shar-Peis are more prone to ear infections due to ear canal shape and structure. Therefore, pet owners of these breeds should be extra vigilant in monitoring the ears and seeking veterinary care at the first signs of ear trouble.

Treatment for Chronic Ear Infections:

The treatment for chronic ear infections in dogs requires a consistent medication plan customized to meet individual needs. Before selecting a long-term treatment for chronic ear infections, testing is essential to determine the cause of the infection.

After treatment, a follow-up test should be conducted to make sure that the medication is working and the infection is not recurring. In addition to treating the infection, ear cleaning can be an important adjunctive therapy for dogs with chronic ear infections.

Some dogs may require regular sterile flush solutions to help flush out any debris in the ear canal. Conclusion:

Ear infections in dogs can be caused by several factors, including ear mites, which can be highly contagious, making good hand hygiene essential.

It is not recommended to treat ear infections at home, and a veterinarian should always evaluate a dog with an ear infection. Chronic ear infections require long-term medication, which can be frustrating for both dogs and owners.

While some breeds may be more prone to ear infections, proper management and close monitoring can help prevent and manage ear infections in all dogs. Importance of Vet Treatment:

Dog ear infections can be uncomfortable and painful for the dog, and prompt veterinary attention is essential.

Ear infections in dogs cannot go away on their own, and self-treatment can lead to complications or mask underlying serious medical conditions. Self-treatment can also have additional risks, such as ruptured eardrums or improper medication choice.

Ruptured eardrums are a painful condition that occurs when excessive pressure is applied during treatment. Additionally, ear infections can have different causes, and not all medications are suitable for every type of infection.

Risks of Self-Treatment:

Self-treatment can also mask underlying medical conditions that need immediate attention. If left untreated, ear infections can spread, leading to more severe ailments such as facial nerve palsy, deafness, or meningitis.

Therefore, early and appropriate veterinary care is essential in treating ear infections, and pet owners should not attempt to self-treat the condition. Specific Breeds Prone to Ear Infections:

Some breeds are more prone to ear infections than others due to their ear shape and structure.

The most common breeds that are predisposed to ear infections include Cocker Spaniels, Springer Spaniels, Shar-Peis, Labrador Retrievers, Golden Retrievers, Schnauzers, and Poodles. Reasons for Predisposition:

Genetics play a significant role in dogs’ predisposition to ear infections.

The ear shape and ear confirmation are essential factors. Breeds with long and floppy ears that cover the ear canal are more prone to ear infections as the ear flap prevents adequate air flow, which leads to moisture and debris buildup.

Additionally, dogs with small ear canals such as Schnauzers and Poodles have less space in their ear canals, leading to increased buildup of earwax and debris. Ceruminous glands, which produce earwax, are also more active in some breeds, leading to a buildup of wax and debris.

Finally, the presence of hair in the ear canal can also make dogs more prone to ear infections. Hair serves as a magnet for debris and wax, providing a breeding ground for bacteria and yeast.


Dog ear infections are a painful and uncomfortable condition that can have serious consequences if left untreated. The risks of self-treatment include complications such as ruptured eardrums and improper medication choices, which can further worsen the condition.

It is also important to note that specific breeds are more prone to ear infections, and genetics, ear shape, ear confirmation, ceruminous glands, and hair in the ear canal all play a part in predisposition to ear infections. Effective treatment for ear infections requires prompt veterinary intervention, appropriate diagnostic testing, and sophisticated medical care.

By working closely with their veterinarians, pet owners can successfully manage and prevent ear infections, promote optimal ear health, and ensure a healthy and happy life for their furry friends. In summary, ear infections in dogs are a common problem that requires prompt and appropriate veterinary care.

Attempts at self-treatment can lead to complications and the masking of underlying medical conditions. Breed predispositions, genetics, ear shape, ceruminous glands, and hair in the ear canal all play a role in the development of ear infections in specific breeds.

By working closely with veterinarians, pet owners can successfully manage and prevent ear infections, promote optimal ear health, and ensure a healthy and happy life for their furry friends. Remember, early detection and appropriate treatment are critical in treating dog ear infections to avoid further complications.
