Yes — dogs can safely consume extra virgin olive oil in moderate amounts. For a complete overview, see our Olive Oil Gastronomy: Cooking, Baking & Culinary Uses guide.For a complete overview, see our Cooking Properties guide.In fact, olive oil offers genuine health benefits for dogs, particularly for skin, coat, and joint health. This is well-documented in veterinary nutritional science1.
The same monounsaturated fatty acids and polyphenol compounds that make olive oil beneficial for humans provide meaningful advantages for dogs as well. And unlike some human foods that are genuinely toxic to dogs (chocolate, grapes, xylitol), olive oil is not among them.
The oleic acid and linoleic acid content in olive oil supports skin barrier function and coat shine. Dogs with dry skin, dull coats, or seasonal itching often show improvement when olive oil is added to their diet in consistent, moderate amounts1.
The omega-6 to omega-3 fatty acid ratio in olive oil is favorable compared to many processed dog foods, which tend to be high in omega-6 from soybean or corn oil bases. Adding EVOO helps restore a more balanced ratio.
The polyphenols in olive oil — particularly oleocanthal and hydroxytyrosol — have documented anti-inflammatory properties that translate to dogs with arthritic joint pain, post-surgical inflammation, or chronic inflammatory conditions1.
A 2019 veterinary nutrition study found that dogs with osteoarthritis showed improved mobility scores when their diet was supplemented with 1–2 tablespoons of extra virgin olive oil daily over a 12-week period.
Olive oil can help with chronic constipation in dogs — a tablespoon mixed into their food acts as a gentle lubricant for the digestive tract. It also supports the absorption of fat-soluble vitamins (A, D, E, K).
The vitamin E content in olive oil (1.9mg per tablespoon) supports immune function. Dogs with recurrent infections or slow wound healing may benefit from the antioxidant support that olive oil provides.
| Dog Size | Safe Daily Amount |
|---|---|
| Small (under 20 lbs) | 1 teaspoon |
| Medium (20–50 lbs) | 1–2 teaspoons |
| Large (50–90 lbs) | 1–2 tablespoons |
| Giant (90+ lbs) | 2–3 tablespoons |
These are general guidelines. The key qualifier is "in the context of a balanced diet" — olive oil should supplement, not replace, a complete and balanced dog food.
High calorie content: Olive oil is 120 calories per tablespoon. For a small dog, this is a significant portion of their daily caloric intake. Overuse leads to weight gain, which itself carries health risks.
Pancreatitis risk: Dogs with a history of pancreatitis should not be given large amounts of fat at once, including olive oil. The sudden influx of fat can trigger a pancreatitis episode. For these dogs, only very small amounts (half a teaspoon) should be used, and only with veterinary approval.
Digestive upset: Some dogs with sensitive stomachs may experience diarrhea or loose stools when introduced to olive oil. Start with half the recommended amount and build up over a week.
Allergies: Rare, but possible. If you see signs of an allergic reaction (facial swelling, itching, hives), discontinue use and consult your vet.
The simplest approach: drizzle 1–2 teaspoons of good Quality EVOO over your dog's regular food once daily. The oil improves the palatability of dry food and ensures fat-soluble vitamin absorption.
For dogs with joint issues: many owners add a tablespoon to the food of senior dogs with arthritis and report observable improvement in mobility within 2–4 weeks.
For dogs with dry skin: mixing olive oil with fish oil (salmon or sardine) provides both omega-3 and omega-9 fatty acids — a more complete approach than olive oil alone.
- Do not give your dog flavored or seasoned olive oil — oils infused with garlic, chili, rosemary, or other seasonings can be problematic
- Do not use lampante oil or any oil not fit for human consumption
- Do not pour a large amount in one serving — spread it across the day
- Do not use olive oil as a replacement for a veterinary therapeutic diet in dogs with diagnosed medical conditions
Extra virgin olive oil is one of the more genuinely beneficial human foods for dogs. Unlike many "people foods" that are given to dogs based on anthropomorphism, olive oil has a legitimate evidence base in veterinary science. Use it consistently, in appropriate amounts, and your dog will likely show improvements in coat quality, joint mobility, and digestive regularity.
Plain extra virgin olive oil is generally safe for dogs in moderate amounts — it provides monounsaturated fat and some antioxidant benefits (vitamin E). Small amounts (up to a teaspoon for medium dogs) added to food can improve coat condition and provide digestive benefits. The polyphenols in olive oil may benefit dogs similarly to humans, though canine dosage would be different. However, garlic-infused olive oil should be avoided (garlic is toxic to dogs), and any oil that has gone rancid should not be given to pets. Plain high-phenol EVOO is the safest choice if supplementing a dog's diet with olive oil.1
Dogs can safely consume small amounts of plain olive oil — approximately 1 teaspoon for small dogs, 1 tablespoon for large dogs, added to their regular food. The caloric density of olive oil (approximately 120 calories per tablespoon) means excessive amounts contribute to weight gain. Start with a small amount (half a teaspoon) and monitor for digestive tolerance. Olive oil should be an addition to a balanced dog diet, not a primary nutrition source. Always introduce gradually to check for individual tolerance.1
Yes — the omega-9 monounsaturated fatty acids and vitamin E in olive oil can improve coat condition when added to dog food. The effect is most visible in dogs with dry skin or dull coat. Regular supplementation (1–2 teaspoons per meal for medium dogs) over 3–4 weeks may produce noticeable improvement in coat luster. This is the same mechanism by which olive oil benefits skin in humans. However, coat condition is also affected by overall diet quality, allergies, and underlying health conditions — olive oil supplementation is not a substitute for a complete balanced diet.1
