Can Dogs Have Olive Oil? 5 Benefits of Olive Oil for Dogs

With its buttery flavor, a drizzle of olive oil can elevate a humble salad or a piece of baguette to a gourmet masterpiece. But can dogs have olive oil, too?

Yes, this Mediterranean elixir isn’t just fit for humans—dogs can enjoy it, too, in moderation. In fact, adding a little bit of this oil to your dog’s diet could offer your tail-wagging pal some impressive health benefits, such as reduced itching from allergies and a shinier coat.

We spoke to vet experts to press out the details on adding olive oil to your dog’s bowl.

Expert info provided by Dr. Christopher Reeder, DVM, veterinary dermatologist at Lighthouse Veterinary Allergy and Dermatology in Spring Hill, TN; Dr. Judy Morgan, DVM, a holistic veterinarian and author in Zebulon, NC; and Dr. Lisa Fox, DVM, owner of Divergent DVM in Wellington, OH.

Is Olive Oil Good for Dogs? 5 Benefits

Olive oil is a natural oil extracted from olives, the fruit of the olive tree. It has long been revered as a superfood for humans, but what benefits can it offer dogs? Let’s take a look.

1. May Improve Skin and Coat Health

Olive oil is rich in nutrients that play a crucial role in maintaining a dog’s skin and fur health. These include vitamin E, omega-3 fatty acids and polyphenols.

Dr. Christopher Reeder, DVM, veterinary dermatologist at Lighthouse Veterinary Allergy and Dermatology in Spring Hill, TN, has seen a noticeable increase in luster and shine in the coats of dogs whose diets were supplemented with olive oil. It takes about 30 days to see a difference, he says.

However, applying olive oil directly to a dog’s coat or skin is not recommended. Most dogs will try to lick off every last drop, which would negate any topical benefits and could cause further skin irritation due to all the licking.

2. May Reduce Itching from Allergies

Many dogs are allergic to substances like pollen, dust and flea saliva. These allergic reactions can make a dog’s skin inflamed and itchy.

Olive oil is primarily made up of a monounsaturated fat called oleic acid. This healthy fat has anti-inflammatory properties that may help ease the itching caused by allergies, says Dr. Reeder.

3. May Support Digestive Health  

Due to its natural laxative properties, olive oil, in modest portions, may help dogs struggling with constipation. It’s important to integrate the oil slowly into your dog’s diet and closely monitor their response. If diarrhea, vomiting or other gastrointestinal issues arise, discontinue giving your dog olive oil.

4. May Support Weight Management

The monounsaturated fats in olive oil can help break down the fat inside fat cells. This may help your dog lose weight or reduce the risk of obesity. The key is to find that sweet spot where your dog reaps this benefit without adding too many extra calories to their diet. See below for serving size suggestions.

5. May Enhance Disease Prevention

While not a panacea, olive oil may help your beloved dog stay by your side a bit longer. Antioxidants like vitamin E may help protect dogs’ cells from free radical damage, potentially reducing the risk of diseases like cardiovascular disease and cancer.

Olive oil also contains chemicals that have been shown to help prevent cognitive decline in humans, says Dr. Judy Morgan, DVM, a holistic veterinarian and author in Zebulon, NC.

It’s currently unknown if and how much these benefits apply to dogs, but there’s no harm in adding it to your dog’s diet in moderate amounts, says Dr. Morgan.

Is Olive Oil Bad for Dogs? 3 Risks

While olive oil certainly isn’t bad for dogs when used appropriately, it’s important to note the potential risks associated with its use. According to Dr. Lisa Fox, DVM, owner of Divergent DVM in Wellington, OH, these include:

1. Weight Gain/Obesity

Olive oil is high in calories. Feeding too much to your dog can lead to weight gain and contribute to obesity, which is associated with various health issues like diabetes, joint pain and heart disease. If your dog is already overweight, avoid adding olive oil to their diet.

2. Pancreatitis

Because olive oil is a fat, excessive intake can trigger pancreatitis in dogs. This is a serious and painful condition that occurs when the pancreas becomes inflamed. Signs of pancreatitis in dogs can include abdominal pain, vomiting, diarrhea, lethargy and loss of appetite.

3. Gastrointestinal Upset

Although a small amount of olive oil can help alleviate constipation, too much can cause diarrhea or vomiting. Dogs with a sensitive stomach might not tolerate olive oil well, even in small doses.

Additions to a dog’s regular diet, whether it’s olive oil, dog treats or other dog-safe human foods, should not make up more than 10 percent of your dog’s total daily caloric intake.

What Olive Oil Is Best for Dogs?

When it comes to choosing the right olive oil for your dog, quality matters. Cold-pressed extra virgin olive oil (EVOO) is the best option as it is produced without the use of heat or chemicals, says Dr. Fox.

This type of olive oil retains the highest levels of antioxidants, vitamins and other beneficial compounds. However, EVOO can go rancid faster than others, so it should be stored in a dark-colored bottle away from high heat, Dr. Morgan adds.

How to Safely Serve Dogs Olive Oil

Introducing olive oil to your dog’s diet should be done cautiously and with attention to safety. Here’s how you can do it right:

Consult Your Vet

Before making olive oil a regular part of your dog’s diet, get approval from your veterinarian.

Start Small

How much olive oil can dogs eat? The amount of olive oil your dog can safely consume depends on their size, weight and overall health. As a general guideline, dogs can have 1 teaspoon of olive oil per 20 pounds of body weight daily. So, a 40-pound dog, for example, could have two teaspoons daily.

That said, begin with a small amount of olive oil—even less than the recommended dose for your dog’s size. This can help you monitor your dog’s reaction to the new addition.

Mix It With Food 

It’s best to mix the olive oil into your dog’s regular wet or dry food. This prevents them from inhaling it or eating it too quickly, which could lead to choking or an upset stomach. Another option is to feed them commercial dog food that includes olive oil (see next section).

Observe Your Dog

Watch for any signs of digestive system discomfort or allergic reaction after introducing olive oil. If you notice diarrhea, vomiting or lethargy, discontinue use and consult your vet.

Be Consistent

If your vet gives the green light and there are no adverse signs, incorporate olive oil into your dog’s diet consistently to provide ongoing benefits.

FAQs About Olive Oil and Dogs

Still have questions? We’ve got answers. Here are some frequently asked questions dog parents have about incorporating olive oil into their furry friend’s diet.


Can you put olive oil on a dog’s skin?

A:Applying olive oil directly to a dog’s skin is not generally recommended. While it might seem like a quick fix for dry skin, most dogs will lick it off. This will negate any potential topical benefits and may further irritate the skin due to the excessive licking. Mixing olive oil into your dog’s food is the recommended method for supporting skin health.


Will olive oil help a dog’s dry skin?

A:Yes, when added to their diet, olive oil may help improve a dog’s dry skin from the inside out. This is thanks to the fatty acids and vitamins in the oil. However, it’s important to consult with your veterinarian if your dog is experiencing dry or flaky skin to assess the underlying cause.


Can you put olive oil on dog food?

A:Yes, you can put olive oil on dog food. In fact, this is the preferred method of adding olive oil to your dog’s diet.


Can I give my dog olive oil every day?

A:Yes, it’s generally safe to give healthy dogs olive oil daily in small quantities. The appropriate daily amount depends on your dog’s overall diet, weight and health status. However, the daily addition of olive oil to your dog’s diet should only be done with your veterinarian’s approval.


Can dogs have olive oil in a salad?

A:While dogs can have olive oil, it’s best to avoid feeding dogs salad, as some common salad ingredients like onions and garlic are toxic to them. If you’re adding olive oil to your dog’s diet, mix it in with their regular, dog-safe food.


Does olive oil help with a dog’s teeth?

A:Plain olive oil isn’t known for providing dental benefits in dogs. To maintain your dog’s dental health, stick with proper tooth brushing, vet-recommended chews and regular dental check-ups. That being said, some research suggests that ozonated olive oil can help as an adjuvant anti-plaque treatment in healthy dogs.
