What are Ear Infections?

An ear infection is most commonly a bacterial, viral or yeast infection of the inner or outer ear.

They are no fun as they can be extremely painful and cause a lot of discomfort. This is because of inflammation and fluid buildup in the ear.

Dogs are easily prone to develop ear infections because of the shape of the ears. Also, the ear canal is a vertical shape which makes it easy for bacteria and other things to get into their ears; therefore, causing uncomfortable ear infections in your dog.

What Causes Ear Infections?

Here is a list of a number of things that may be the source of an ear infection in your loving furry pet.

With allergies it is important to find out what exactly your dog is allergic to; therefore, you can help stop the re-occurrence of ear infections in your dog.

Ear Mites:  Ear mites love being in an environment where it is warm, moist and dark, which is why your dog’s ears make it an ideal location.

However, some dogs may be allergic to these creatures or find them irritating. This can cause them to itch and scratch their ear, which cause trauma and infections that can be the leading cause to ear infections.

Luckily for dogs, ear mites are less of an issue in dogs and more so with cats.

Bacteria and Yeast: There are no particular bacteria or yeast that can cause the development of an ear infection, but there are a number of different kinds. Usually, your dog’s immune system can fight off bacteria and yeast to help avoid and destroy an ear infection.

However, due to allergies, a cold, or even a change in the environment can make your dog’s immune system weaker. As a result bacteria and yeast can grow in the ear causing an infection.

Trauma: When your dog is excessively scratching their ears it can cause irritation and lead to an ear infection. Even prior injuries or surgeries can make your dog more prone to develop ear infections for frequently compared to other dogs.

Hormonal: In some situations having too many hormones or hormones not acting in the correct manner can cause skin and ear problems. As a result, even in some circumstances can cause your dog to develop ear infections.

The Environment: Your dog’s ears are warm, dark, deep and moist which makes it the perfect home for bacteria and yeast to live and grow in. This can cause your dog to develop a serious ear infection.

Too Much Water: Numerous and frequent bathing and swimming can cause ear infections in your dog. As a dog’s ear canal faces downwards it makes it difficult for water to escape.

Instead, it sits in the air causing ear infections and more prone for bacteria to grow and develop.

Heredity: Sometimes ear infections are just heredity. This means that because of your dogs breed and genetic genes they are just more prone towards developing ear infections.

Floppy Ears: Dogs with floppy ears are more likely to face more problems with ear infections and other ear related problems.

Having long ears will prevent circulation which will not allow evaporation and as a result make the ears more moist. This makes it a perfect environment for bacteria to grow in causing ear infections.
