It isn’t uncommon for dogs to have problems with their ears. Canines with droopy ears are far more prone to these problems since their downturned ears tend to trap debris and moisture. However, any dog can experience ear problems. 

Luckily, you can avoid and even cure many ear issues with the proper ear drops. Most ear drops available over the counter are designed to clean your pet’s ears only, though this is often enough to avoid ear infections in most dogs. However, you can also find various medicated drops that are often cheaper than what you’d find at a vet’s office. 

Sometimes, vets may even recommend these drops to prevent and cure infections. 

However, not all drops are made equal. Below, we’ve reviewed some of the best ear drops on the market for dogs that really work.

How to Choose the Right Ear Drops 

There are several factors that can affect which ear drops are best for your canine. There is no one-size-fits-all answer, which is why we included four different options in our reviews. 

Here are some things that you may need to keep in mind:

  • Use
  • Ingredients
  • Cost
  • Effectiveness

We’ll take a look at each factor one by one. 


There are two main uses for ear drops: treating existing infections and preventing future ones. Which option you fall into depends on your dog’s current needs. 

For those that are prone to ear infections but not currently experiencing one, you probably need a strong cleanser and preventative drop. These aren’t always medicated. Instead, they’re designed to prevent the environment that encourages bacteria and yeast to grow in the first place. 

However, for dogs with minor ear infections, something medicated is typically called for. The exact medication needed will depend on the agent infecting your dog’s ears. Often, you’ll need to visit the vet to find out. 

We included medicated ear drops in our reviews as well — most of which contain multiple kinds of medication to fight just about anything. 


Certain ingredients work better for certain things. If your dog has a yeast infection, then an antibiotic won’t help. Usually, the only way to tell exactly what medication they need is to visit the vet, who may prescribe something. However, you can sometimes find ear drops over the counter that contain the same medication for less money, so be sure that you check our reviews above before purchasing an over-priced option from your vet. But only do so with your vet’s approval.

With that said, you do want to ensure that your chosen ear drops include some kind of anti-inflammatory. No matter what sort of infection your dog has, it will likely cause inflammation, which is the main source of pain and discomfort. Therefore, treating this inflammation is recommended. It will make your dog feel better and helps fight the underlying cause. 


The cost of ear drops is going to be an important aspect for most people. You don’t want to overpay for something when you can get the same results with a less expensive product. Therefore, we were very conscious of price when suggesting products. We chose the products that got the best results for the price. 

With that said, only you know your budget. Therefore, only you can decide which product is acceptable from a cost perspective.


Of course, no one wants to purchase a product that just doesn’t work. For this reason, we highly recommend reading reviews like ours for information on whether or not the product actually works. Over-the-counter ear drops are not regulated, so companies can literally sell anything and make any claims they like.

How to Put Ear Drops in Your Dog’s Ears

Purchasing the correct ear drops is typically only half the problem. The other half of the process is actually getting the ear drops into your dog’s ears. 

As you might imagine, this can be difficult. However, it will depend mostly on your canine. Some dogs don’t seem to care much and will sit there happily, while others will fight like you’re trying to kill them. Having some sort of training is helpful in this situation, especially in regards to grooming. If the dog is used to sitting still to have their ears trimmed, then ear drops are much easier to apply. 

Either way, you’ll want to follow these general steps:

  1. Hold the ear drops in your dominant hand. While you may be tempted to hold your dog in your dominant hand, you’ll need more finesse in hand with the ear drops. If the ear drops need to be refrigerated, be sure to warm them to room temperature before adding them to your dog’s ear. Never heat medication on the stove or in the microwave. 
  2. With your other hand, hold your dog’s ears. You’ll need to gently pull your dog’s ear open (if it is floppy). You should have a clear view of the canal of your dog’s ear. 
  3. Apply the correct number of drops. Be sure to check with your vet or the directions that came with the medication for the correct number of drops. We know that it can be difficult to apply for the correct number when your dog is thrashing around. Luckily, most drops are estimates. So, if you apply one too many or too few, then it typically isn’t a huge problem. 
  4. Rub the base of your dog’s ear. You’ll need to rub your dog’s ear to encourage the drops to go deeper into the ear canal. Be gentle, as your dog’s ears are already sensitive.
  5. Give praise. When you’re done, give your dog plenty of attention and treats. You want the experience to be a positive one. 

If you have a particularly difficult dog or a larger one, you may need to get another person to help you with the process. Try to make it as positive as possible. If you can distract your dog with treats or attention, do so. 

Ear Infections in Dogs

Most ear drops are designed to prevent or treat ear infections. Some dogs are more prone to ear infections than others, such as dogs with hairy and floppy ears. 

Ear infections are painful, so most dogs will shake their head or mess with their ears as they attempt to relieve the discomfort. Some may scratch their ears as well. Usually, the dog’s ears may become inflamed as well. A common sign of infection is smelly ears. However, black or yellow discharge can occur as well. 

In chronic cases, the ears may get crusty. 

Ear infections and ear mites are commonly confused with one another. Therefore, it is essential to visit your vet so that they can help you tell the difference. Ear infections are far more common in adult dogs than ear mites. So, if you’re noticing these symptoms in adult dogs, it is probably ear infections. 

There are several things that cause ear infections, including funguses and bacteria. Therefore, it can be difficult to tell exactly what medication you should use for your canine. Many over-the-counter medications include multiple ingredients so that they can handle infections from multiple causes. However, if you visit your vet, they can pinpoint the reason and prescribe a specific medication. 

To figure out the cause of the ear infection, vets will look at your dog’s ears. Next, they can take a look at the material in the ear canal to determine the cause of the infection. Bacteria and funguses can be differentiated at this level. Sometimes, chronic ear infections need to be cultured to determine the exact pathogen causing the problem. 

Ear infections usually require medicated drops. You can get these prescribed at the vet. However, some over-the-counter options include the same medication vets use for cheaper. Therefore, we recommend asking your vet about over-the-counter options, including those we mentioned in our reviews. 

For chronic ear infections, your dog may need to have other tests run. For instance, some ear infections are caused by allergens are similar underlying illnesses. To prevent the ear infections from reoccurring, your canine will need these underlying problems handled as well. 

How to Prevent Ear Infections in Dogs

There are several steps you can take to avoid ear infections in dogs. Ear infections typically only occur under certain conditions. If you can avoid these conditions, then your dog likely won’t get an infection. Here’s what to keep in mind:

  • Limit moisture. Moisture causes fungus and bacteria to grow, which can cause ear infections. Anytime your dog has contact with water, be sure to dry the inside of their ear with a cotton ball. 
  • Clean their ears. Always clean your dog’s ears regularly. Use water and a cotton ball at the very least, though a commercial cleaning product can often do more to prevent infections. Once a week is often enough for most dogs, though some that are prone to ear infections may need more.
  • Remove visible debris. Debris in your dog’s ear can trap dirt and moisture behind it, which will cause infections. Therefore, always clean your dog’s ears when you notice debris.
  • Trim any hair. If your dog is hairy at all, we recommend trimming the inside of their ears thoroughly. You can do this at home or visit a groomer. This hair can trap moisture, which is the cause of most infections. 
  • Keep an eye out for infections. Smell your dog’s ears regularly and keep an eye out for redness. If you catch ear infections early, they are much easier to treat.

The Best Ear Drops for Dogs: Reviewed and Ranked FAQs (Frequently Asked Questions) 

Can I use human ear drops on my dog?

You should never use human ear drops in your dog’s ears unless you are directed to by a vet. Human ear drops often contain medications that can be harmful to dogs. Therefore, not only will they potentially not help, but they can also cause serious reactions.

Dog and human ears are simply not the same. Therefore, you can’t use the same ear drops for both species.

Instead, we recommend choosing ear drops off of our list above – all of which are designed specifically for dogs. We’ve included medicated drops as well as simple cleansers, so you should be able to find something for just about every dog.

Can I treat my dog’s ear infection without going to the vet?

While you may be able to treat your dog’s ear infection without going to the vet, that is not recommended. Ear infections are usually very easy to treat. However, they can lead to complications over time if they are not treated correctly.

Therefore, you should visit your vet anytime you think that your dog may have an ear infection. However, that doesn’t necessarily mean that you’ll need to pay for expensive treatments. Often, you can ask your vet about over-the-counter treatment options like the ear drops we included above. Some of them include the same types of medications that vets typically prescribe.

Can you use olive oil in dog’s ears?

Olive oil can help reduce the amount of wax in a dog’s ears. However, it is not as great as other cleaner options. Purchasing a commercial cleaner is typically always better than using olive oil. In fact, some commercial cleaners include olive oil and a variety of other helpful ingredients.

Medications work best on clean ears, so it is essential to keep their ears clean when they have an infection. Infections can also be prevented by keeping the dog’s ears clean.
