You’re standing in your kitchen, drizzling olive oil over your salad, and your dog gives you that look. The one that says, “Hey, can I have some of that?” If you’ve ever wondered whether can dogs have olive oil is actually safe, you’re not alone. The good news? Yes, dogs can have olive oil, and in the right amounts, it’s actually pretty beneficial. But like most things in dog nutrition, there’s a right way and a wrong way to do it.
I’ve been working with dogs for over a decade as a vet tech, and I’ve seen firsthand how olive oil can improve coat quality, support joint health, and even help with digestion. But I’ve also seen owners accidentally overdo it and end up with some messy cleanup situations. Let’s break down everything you need to know about olive oil for dogs—the real benefits, the risks, and exactly how much is safe.
Is Olive Oil Safe for Dogs?
Here’s the straight answer: can dogs have olive oil? Yes, absolutely. Olive oil is not toxic to dogs. In fact, it’s a natural food that many dogs can tolerate well. Unlike some human foods that are genuinely dangerous (like chocolate, grapes, or xylitol), olive oil isn’t on the “forbidden” list.
The ASPCA and most veterinary sources confirm that olive oil is safe for canine consumption. That said, “safe” doesn’t mean you should pour it on everything your dog eats. It’s high in fat and calories, which means moderation is key. Think of it like how coffee is safe for humans, but you wouldn’t drink a gallon a day.
According to the American Kennel Club, many common human foods are safe for dogs when given appropriately. Olive oil falls into this category—it’s a whole food with no artificial additives that would harm your pup.
The real question isn’t whether olive oil is safe, but whether it’s right for your specific dog. Some dogs have sensitive stomachs. Some are overweight. Some have pancreatitis or other conditions that make high-fat foods problematic. That’s why it’s important to understand the context before adding it to your dog’s diet.
Health Benefits of Olive Oil for Dogs
If you’ve been wondering whether there’s actually a point to giving your dog olive oil beyond “it won’t hurt them,” the answer is yes. There are legitimate health benefits—assuming your dog is a good candidate for it.
Coat and Skin Health
This is the big one. Olive oil is rich in omega-9 fatty acids and antioxidants. These compounds help reduce inflammation in the skin and can make your dog’s coat shinier and softer. If your dog has dry, flaky skin or a dull coat, a small amount of olive oil can genuinely help. I’ve recommended it to owners whose dogs were struggling with minor skin issues, and they often see improvement within a few weeks.
The polyphenols in olive oil also act as antioxidants, which means they help protect skin cells from damage. It’s not a miracle cure for serious skin conditions, but for maintenance and minor issues, it works.
Joint and Brain Support
Olive oil contains compounds like oleocanthal, which has anti-inflammatory properties similar to NSAIDs (non-steroidal anti-inflammatory drugs). For older dogs with arthritis or younger dogs prone to joint issues, this can be helpful. It won’t replace prescribed medication, but it can be a supportive addition.
The antioxidants in olive oil also support cognitive function, which is especially relevant for senior dogs. Some research suggests that polyphenols may help slow cognitive decline in aging dogs.
Digestive Support
A small amount of olive oil can help with constipation and support healthy digestion. It acts as a mild lubricant in the digestive tract. However—and this is important—too much will have the opposite effect and cause diarrhea. We’ll talk about amounts in a minute.
Heart Health
Olive oil has been linked to cardiovascular benefits in humans for decades. While research in dogs is less extensive, the same compounds that support heart health in people likely benefit dogs too. It helps maintain healthy cholesterol levels and supports blood vessel function.
How Much Olive Oil Can Dogs Have?
This is where most owners go wrong. They think, “If olive oil is healthy, more must be better.” Nope. Olive oil is about 120 calories per tablespoon. For a 30-pound dog, that’s a significant chunk of their daily caloric intake.
The general guideline is:
- Small dogs (under 20 lbs): ¼ teaspoon per day
- Medium dogs (20-50 lbs): ½ to 1 teaspoon per day
- Large dogs (50+ lbs): 1 to 1.5 teaspoons per day
These amounts can be given several times per week, not necessarily daily. Some vets recommend 2-3 times per week as a safer approach. Think of it as a supplement, not a staple.
If you’re adding olive oil to your dog’s food, reduce their regular food portion slightly to account for the extra calories. Otherwise, you’re looking at gradual weight gain, which leads to obesity, joint problems, and other health issues.
Start small. If your dog has never had olive oil before, begin with just a few drops mixed into their food. Watch for any digestive upset over the next 24-48 hours. If everything looks good, you can gradually increase to the recommended amount.
Best Types of Olive Oil for Dogs
Not all olive oils are created equal. Here’s what to look for:
Extra Virgin Olive Oil
This is your best choice. Extra virgin olive oil is cold-pressed and minimally processed, which means it retains the most polyphenols and antioxidants. It has the strongest flavor, which actually helps—your dog gets more benefit from a smaller amount because they might be more interested in the food.
Virgin Olive Oil
A solid second choice. It’s still cold-pressed but slightly more processed than extra virgin. Still plenty of beneficial compounds.
Regular Olive Oil
This is refined and loses most of the beneficial polyphenols during processing. If you’re going to use it, you might as well use extra virgin—there’s no real downside to the higher quality version.
Avoid These
- “Light” or “pure” olive oil: Heavily refined, minimal benefits
- Olive oil blends: May contain other oils that aren’t ideal for dogs
- Flavored olive oils: Often contain garlic, herbs, or other additives that can be problematic
- Rancid or expired olive oil: Can cause digestive upset
Store your olive oil in a cool, dark place. It oxidizes when exposed to light and heat, which reduces its health benefits and can create compounds that aren’t good for anyone—human or dog.
Risks and Side Effects to Watch For
Olive oil is generally safe, but there are real risks if you don’t use it carefully.
Digestive Upset
The most common issue is diarrhea or loose stools. This happens when you give too much. If your dog suddenly has soft stool after you introduced olive oil, cut back the amount or stop for a few days. Their digestive system will usually normalize quickly.
Pancreatitis Risk
This is the big concern for high-fat foods. Pancreatitis is inflammation of the pancreas, and it can be triggered or worsened by high-fat foods. If your dog has a history of pancreatitis, skip the olive oil entirely. Talk to your vet first.
According to PetMD, dogs with pancreatitis need to be on low-fat diets, and even small amounts of added oils can be problematic.
Weight Gain
Olive oil is calorie-dense. If you’re not adjusting your dog’s regular food portion when you add olive oil, they’ll slowly gain weight. Obesity in dogs leads to joint problems, diabetes, heart disease, and a shortened lifespan. It’s not worth it.
Allergic Reactions
Rare, but possible. Some dogs might have a sensitivity to olives or olive oil. Signs include itching, hives, swelling, or vomiting. If you see any of these after introducing olive oil, stop immediately and contact your vet.
Safety Warning: Never give your dog olive oil if they have a known history of pancreatitis, are significantly overweight, or have a sensitive stomach. Always consult your vet before adding supplements or new foods to your dog’s diet, especially if they’re on medication or have existing health conditions.
How to Serve Olive Oil to Your Dog
There are several ways to incorporate olive oil into your dog’s diet safely:
Mixed Into Regular Food
This is the easiest method. Simply drizzle the recommended amount over your dog’s kibble or wet food and stir it in. The food will help distribute the oil evenly, and your dog will eat it without hesitation. Make sure to reduce the food portion slightly so you’re not adding extra calories.
Drizzled Over Vegetables
If you’re giving your dog vegetables (which is great, by the way), a small drizzle of olive oil makes them more palatable and helps with nutrient absorption. Carrots, green beans, and sweet potatoes are all dog-friendly vegetables that pair well with olive oil.
Mixed With Protein
You can mix olive oil with lean proteins like scrambled eggs or salmon skin. Both are excellent for dogs, and the olive oil enhances their nutritional profile. This is a nice occasional treat.
In Homemade Dog Food
If you’re making homemade dog food, olive oil can be part of the fat component. However, homemade diets need to be carefully balanced to ensure your dog gets all necessary nutrients. Talk to your vet or a veterinary nutritionist before making this switch.
What NOT to Do
- Don’t give olive oil by itself as a “treat”
- Don’t mix it with foods that already contain high fat (like peanut butter)
- Don’t use it as a substitute for medication or prescribed treatments
- Don’t give it to puppies without vet approval
Dogs Who Shouldn’t Have Olive Oil
Even though olive oil is generally safe, some dogs should avoid it entirely.
Dogs With Pancreatitis
This is non-negotiable. High-fat foods can trigger pancreatitis or make it worse. If your dog has ever had pancreatitis, talk to your vet before introducing any new foods, including olive oil.
Overweight or Obese Dogs
If your dog is already carrying extra weight, adding calories from olive oil will make the problem worse. Focus on weight management first. Once they’re at a healthy weight, you can discuss olive oil with your vet.
Dogs With Sensitive Stomachs
Some dogs have chronically sensitive digestive systems. Olive oil can trigger diarrhea or vomiting in these dogs. If your dog falls into this category, skip it or only use tiny amounts under vet supervision.
Dogs on Certain Medications
Some medications interact with high-fat foods. If your dog is on medication, ask your vet whether olive oil is okay. It’s a quick conversation but an important one.
Puppies
Puppies have different nutritional needs than adult dogs. Their diets should be carefully controlled to ensure proper growth and development. Don’t add olive oil to a puppy’s diet without vet approval.
Dogs With Gallbladder Issues
Dogs with gallbladder disease or a history of gallstones should avoid high-fat foods. Olive oil can trigger gallbladder problems or make existing ones worse.
If you’re unsure whether your dog falls into any of these categories, your vet can give you a clear answer. It’s worth asking.
Frequently Asked Questions
Can I give my dog olive oil every day?
– Technically yes, but it’s not necessary. 2-3 times per week at the recommended dosage is usually sufficient. Daily use increases the risk of weight gain and digestive issues. If you want to give it more frequently, use smaller amounts and monitor your dog’s weight and stool consistency.
Is extra virgin olive oil better than regular olive oil for dogs?
– Yes. Extra virgin olive oil has more polyphenols and antioxidants because it’s minimally processed. You’ll get more health benefit from a smaller amount. It’s worth the extra cost.
What if my dog accidentally drinks a bunch of olive oil?
– Don’t panic. A large amount of olive oil will likely cause diarrhea or vomiting, but it’s not toxic. Monitor your dog for digestive upset over the next 24-48 hours. If they seem fine, no action is needed. If they’re vomiting repeatedly or have severe diarrhea, contact your vet.
Can olive oil help with my dog’s dry skin?
– Yes, it can. Olive oil’s fatty acids and antioxidants support skin health. However, if your dog has severe skin issues, there’s usually an underlying cause (allergies, parasites, infection) that needs to be addressed. Use olive oil as a supportive measure, not a replacement for proper diagnosis and treatment.
Is olive oil better than fish oil for dogs?
– They’re different. Fish oil is higher in omega-3 fatty acids, which are particularly good for inflammation and joint health. Olive oil is higher in omega-9s and polyphenols. Both have benefits. Some vets recommend using both in small amounts, while others prefer one or the other. Ask your vet which is best for your dog’s specific situation.
Can I mix olive oil with my dog’s kibble?
– Absolutely. Mix it directly into their food. Just make sure to reduce the kibble portion slightly to account for the extra calories. Some dogs might be picky at first, but most warm up to it quickly.
What are the signs that olive oil isn’t working for my dog?
– If your dog develops diarrhea, vomiting, weight gain, or any other negative symptoms after you introduce olive oil, stop giving it and talk to your vet. Olive oil isn’t right for every dog, and that’s okay.
Can puppies have olive oil?
– Not without vet approval. Puppies have specific nutritional requirements for proper growth and development. Adding olive oil could interfere with their diet balance. Wait until your dog is fully grown, and then ask your vet if olive oil is appropriate.
Does olive oil help with constipation in dogs?
– Yes, a small amount can help. It acts as a mild lubricant in the digestive tract. However, if your dog is chronically constipated, there’s usually an underlying cause that needs to be addressed. Don’t use olive oil as a long-term solution without talking to your vet.
Can I use olive oil to help with my dog’s itchy skin?
– It can help as a supportive measure, but itching usually indicates an underlying problem like allergies, parasites, or infection. Olive oil might provide temporary relief, but you need to identify and address the root cause. See your vet if your dog is scratching excessively.
The Bottom Line on Olive Oil for Dogs
So, can dogs have olive oil? Yes, they can. And when used appropriately, it offers real health benefits for coat quality, joint support, and overall wellness. But—and this is important—it’s not a miracle supplement. It’s a small addition to an already balanced diet.
Start small. Monitor your dog’s response. Adjust portions based on their weight and digestive health. And most importantly, talk to your vet before making any changes to your dog’s diet, especially if they have existing health conditions.
The best diet for your dog is one that keeps them at a healthy weight, provides complete nutrition, and supports their individual health needs. Olive oil can be part of that picture, but it’s not the whole story. Think of it as one tool in your toolkit for keeping your dog healthy and happy.
Remember, your vet knows your dog’s medical history and can give you personalized advice. When in doubt, ask. It’s always better to be cautious with something as important as your dog’s health.
