There could be several reasons why your dog’s ears smell.

Early diagnosis and treatment go a long way towards relieving the ailing pooch, as well as some preventive measures.

According to experts, there are three main parts of a dog’s ear: the outer, middle, and inner ear canal.

Under the outer part, there is the pinna and the ear canal.

The pinna captures sound waves which go through the ear canal to the eardrum, located in the middle ear.

The middle ear also contains 3 bones named the hammer, anvil, and stirrup.

The inner ear houses the cochlea which enables hearing and the vestibular system which creates balance.

Dogs’ ears also come in different shapes. While some are long and droopy like the Cocker Spaniel, others are more erect like the Siberian Husky.

There are many variations, but they tend to fall under droopy or erect ear shapes.

Top 4 Reasons Why Your Dog’s Ears Smell

As we mentioned in the introductory part, ear problems are common with dogs.

All dogs can get these issues, but those with floppy or hairy ears are more prone to it.

If you notice your dog’s ears smelling, here are four reasons that can cause this problem:

1. Ear infection

The most common reason for an ear issue is an infection, but don’t be too quick to resort to this as other possible problems could make a dog’s ear smell.

With ear infections, you will notice other symptoms like swellings or red spots.

2. Allergies

Allergic reaction is another issue that can make a dog’s ears smell. When your dog comes in contact with an allergen it is allergic to, it may make the ear smell.

3. Ear mites

Ear mites may get into your dog’s ears and reproduce. They cause itchiness, discomfort, and a bad smell.

Ear mites are highly contagious and should be treated immediately.

4. Objects in the ear

It isn’t strange to find objects lodged in a dog’s ears. These objects can block off ear ventilation, resulting in an offensive odor.

They also make the dog uncomfortable and can even lead to bleeding.

Smelly Dog Ear Infection Treatment (Pro Tips)

When you notice the bad odor, the best thing to do is take your pup to the veterinarian.

Do not leave the problem for long as it puts your dog at risk.

The veterinarian is also in the best position to get an accurate diagnosis and prescribe medications.

You have a part to play as well, so here are some pro tips that can facilitate healing:

  • Administer prescribed drugs: When the veterinarian prescribes any medication, follow the instructions given accurately. Do not go overboard or stop halfway, even if your dog appears to be getting better. 
  • Calm your pooch: Ear issues are painful and uncomfortable, yet you have to stop your dog from being antsy and causing more issues with excessive itching. 
  • Hygiene is essential: Clean the dog’s ears with a prescribed ear cleanser. Do not clean before diagnosis, however, as it makes the vet’s job harder. 

Getting a good ear cleaner is key to keeping your dog’s ear infection-free.
