Can My Dog Eat Olives? A Vet-Reviewed Guide to Safety, Risks, and Health
This Mediterranean fruit offers fats and antioxidants, yet deserves occasional servings.

Olives are a flavorful and nutrient-rich staple in many human diets, especially in Mediterranean cuisine. But as a dog owner, you may wonder: Can dogs eat olives? What are the risks, and are there any health benefits? This comprehensive, veterinary-backed guide answers these questions and more, helping you make informed decisions about treating your pup with this unique fruit.
Are Olives Safe for Dogs?
Yes, dogs can eat plain, pitted olives in moderation. However, there are several important warnings and caveats. Most olives sold in stores are brined, cured, or stuffed with ingredients that can be harmful to dogs. The safest olives for your dog are those that are plain, unsalted, unseasoned, and completely pitted. Even then, they should be given only occasionally as a treat, not as a regular part of your dogâs diet.
- Uncured, plain olives (without pits) are the safest option for dogs.
- Common store-bought olives are usually high in sodium due to brining.
- Olives stuffed with garlic, cheese, or other ingredients pose additional health risks.
According to Dr. Jessica Apted, DVM, while a single olive or two off the ground probably won’t harm your dog, brined or seasoned olives should be avoided due to their high salt and additive content.
What Are the Health Benefits of Olives for Dogs?
Olives offer some nutritional value, though itâs important to remember that a well-balanced dog food already supplies the nutrients your dog needs. Some potential benefits include:
- Healthy fats: Olives, especially those used to make extra-virgin olive oil, contain unsaturated fats that can support heart health and coat quality.
- Antioxidants: Compounds in olives can help reduce inflammation and protect cells from oxidative damage.
- Vitamins and minerals: Olives contain moderate amounts of vitamin E, vitamin K, iron, calcium, and magnesium, although these are not essential additions for dogs.
Despite these benefits, too many olives can add unnecessary calories and fat to your pet’s diet, and the risks often outweigh the rewards.
What Are the Risks of Dogs Eating Olives?
There are several risks associated with giving olives to your dog:
- High sodium: Most olives are cured or preserved in brine, making them very high in salt. Too much sodium can cause dehydration, increased thirst, vomiting, diarrhea, and even salt poisoning in rare cases.
- Choking and intestinal blockage: Olive pits (stones) are a choking hazard and can cause intestinal blockage or even crack your dog’s teeth.
- Dangerous ingredients: Stuffed, seasoned, or marinated olives often contain toxic substances for dogs, such as garlic, onions, chili peppers, or alcohol.
- Digestive upset: Even plain olives can cause diarrhea or vomiting in some dogs, especially if eaten in larger quantities.
- Unsuitable for certain dogs: Puppies, dogs with kidney or heart problems, and dogs on sodium-restricted diets should avoid olives entirely.
Specific Risks by Olive Type
Olive Type | Risk Factors | Dog Safe? |
---|---|---|
Plain, pitted (not brined) | Minimal risk if given occasionally | Yes (in moderation) |
Brined/Cured (high sodium) | High sodium, can cause dehydration or worse | No |
Stuffed (cheese, garlic, etc.) | May contain toxic/dangerous fillings | No |
With pit/stone | Choking, broken teeth, intestinal blockage | No |
Alcohol-soaked | Toxic; alcohol is poisonous to dogs | No |
Marinated/flavored | Often contain garlic, onion, spices | No |
Olive Pits: A Hidden Danger
Never offer olives with pits to your dog. The pit can cause choking and, if swallowed, lead to intestinal blockage or damage. If your dog chews the pit, it can also crack a tooth, leading to pain or infection.
If you suspect your dog has eaten an olive pit and is showing signs of pain, constipation, vomiting, or refusing food, contact your veterinarian immediately.
Which Olives Can Dogs Eat?
The safest olives for dogs are:
- Plain, unseasoned olives
- Completely pitted (stone removed)
- Not brined, cured, or marinated
While both black and green olives are technically safe if they meet the above criteria, in practice, most store-bought olives contain added sodium and preservatives. Always check the ingredient list and nutrition label before giving olives to your dog.
How to Safely Offer Olives to Your Dog
- Choose plain, unsalted, and unseasoned olives.
- Remove the pit completely before offering to your dog.
- Cut into small pieces for safer consumption, especially for smaller dogs.
- Limit to no more than one or two pieces occasionally as a treat.
- Monitor your dog for signs of digestive upset or allergies.
- When in doubt, skip olives and offer dog-safe fruits instead (like blueberries or apple slices without seeds).
Can Puppies Eat Olives?
Puppies should not be given olives due to their heightened sensitivity to salt and smaller physical size, which increases the risk of choking or digestive issues. Instead, stick to puppy-specific snacks and training treats.
What Should I Do If My Dog Ate Olives or Olive Pits?
- If your dog accidentally eats a small number of plain, pitted olives, monitor for any signs of stomach upset.
- If your dog eats brined, stuffed, or seasoned olives, watch closely for signs of poisoning or distress (vomiting, diarrhea, excessive thirst, drooling, abnormal behavior).
- If your dog ingests an olive pit, watch for choking, coughing, or signs of intestinal blockage (constipation, vomiting, abdominal pain). Contact your veterinarian promptly if any symptoms appear.
- If your dog has an underlying health condition or is a puppy, consult your vet even if no immediate symptoms appear.
Are There Better Treat Alternatives?
While olives are not toxic, the risks often outweigh the benefits. Instead, opt for safer, nutritious dog treats, such as:
- Carrot sticks
- Plain apple slices (no seeds)
- Blueberries
- Fresh green beans
- Commercial dog treats designed for balanced nutrition and dental health
Can Dogs Eat Olive Oil?
Dogs can safely consume small amounts of extra virgin olive oil. Olive oil is rich in antioxidants and healthy fats, which can benefit your dogâs skin, coat, and general health. However, olive oil is high in fat and calories, which can contribute to weight gain if overfed, especially in dogs prone to pancreatitis. Always consult your veterinarian before adding any new food or supplement to your dogâs diet.
- Moderation is key: A small drizzle over food is sufficient.
- Choose only high-quality, extra virgin olive oil.
- Avoid flavored or infused olive oils, which may contain garlic or other harmful additives.
Frequently Asked Questions (FAQs)

At most, one or two plain, pitted olives as an occasional treat. Too many can lead to stomach upset or, with repeated exposure, increased health risks.

Summary: Should I Feed My Dog Olives?
Plain, pitted olives are not toxic to dogs and can be offered in moderation as a rare treat. However, most olives available for purchase are processed with added salt, brine, and seasonings that make them unsafe. Stuffed, marinated, and flavored olives should always be avoided; the same goes for olives with pits.
When in doubt, stick to veterinarian-approved dog treats and foods made specifically for your petâs health. Always consult your veterinarian if you have any concerns or if your dog accidentally consumes a questionable food.
