Can Dogs Eat Olives? Safety, Risks, and Healthy Alternatives
Learn the facts about feeding olives to your dog, including benefits, risks, and vet-approved alternatives for a happier, healthier pup.
Olives are a favorite snack and ingredient in kitchens worldwide, valued for their flavor and health benefits for humans. But when those curious canine companions take interest, many pet owners wonder: Can dogs safely eat olives? Discover the facts, veterinary guidance, and healthier alternatives to keep your dog happy and healthy.
Are Olives Safe for Dogs?
Olives themselves are not inherently toxic to dogs, and in specific forms and small amounts, they can be safe to consume. Dr. Jessica Apted, DVM, emphasizes that only plain, unsalted, and unseasoned olives — typically both black and green varieties — are considered dog-safe. Most olives sold commercially, however, are cured, pickled, or brined and thus high in sodium or contain other potentially dangerous ingredients for pets.
If your dog snatches up one or two plain olives from the floor, it is unlikely to cause harm. But most household olives are prepared with added salt, marinades, or fillings, rendering them less suitable or even dangerous for canine consumption.
Risks Associated with Dogs Eating Olives
While the flesh of plain olives is generally not toxic, there are noteworthy risks associated with feeding them to your pet:
- High Sodium Content: Most olives are cured or pickled in salty brines. Excess sodium can lead to dehydration, elevated blood pressure, and — in severe cases — sodium ion poisoning or salt toxicosis. Symptoms may include excessive thirst, vomiting, diarrhea, tremors, seizures, and lethargy.
- Choking and Dental Hazards: Olive pits are a serious choking hazard. Dogs biting into pits may also suffer from cracked or broken teeth, leading to pain and expensive veterinary care.
- Intestinal Obstruction: If swallowed, olive pits can lodge in the intestinal tract, potentially resulting in dangerous blockages or obstructions that require surgery.
- Unhealthy Ingredients: Marinated and stuffed olives may contain garlic, onions, spicy peppers, or even cheese and nuts. Garlic and onion are toxic to dogs, and fatty or spicy fillings can irritate the digestive tract or introduce additional health hazards.
- Alcohol-Soaked Olives: Some olives are used in alcoholic cocktails. Even small amounts of alcohol can be dangerous or fatal to dogs, and smaller breeds are at higher risk for toxicity.
| Olive Preparation | Risk Factors | Dog-Safe? |
|---|---|---|
| Plain, unsalted, pitted | Low risk (in moderation) | Yes, in moderation |
| Brined, pickled | High sodium | No |
| Stuffed (cheese, garlic, nuts) | Toxic ingredients, choking | No |
| With pit (unpitted) | Choking, broken teeth, intestinal blockage | No |
| Alcohol-soaked | Alcohol toxicity | No |
Risk of Olives by Type
Let’s break down the different types of olives commonly found in homes and their respective dangers for dogs:
- Pitted Olives: Contain the hard pit, increasing risks of choking and dental injury. Never offer these to dogs.
- Marinated Olives: Frequently marinated in garlic, onions, peppers, or spicy seasonings — many of which are toxic to dogs.
- Stuffed Olives: Stuffings like cheese, anchovy, almond, or other foods lack nutritional benefit for dogs. Many are outright dangerous.
- Alcohol-Soaked Olives: Sometimes used as cocktail garnishes. Any alcohol is unsafe and potentially fatal for dogs — never give these.
What Should You Do if Your Dog Eats Unsafe Olives?
If your dog consumes large amounts of high-sodium, marinated, or alcohol-soaked olives, or ingests a pit, you should:
- Contact your veterinarian or an emergency animal hospital immediately.
- Watch for symptoms such as choking, vomiting, diarrhea, tremors, respiratory issues, or sudden behavioral changes.
- If you suspect dental injury (cracked tooth), seek veterinary dentistry care as soon as possible.
Are There Any Health Benefits for Dogs Eating Olives?
In rare cases where olives are plain, uncured, unsalted, and pitted, there may be some modest nutritional benefits. Olives contain:
- Healthy fats (mainly monounsaturated fats), which may support heart health and help reduce inflammation.
- Antioxidants, such as vitamin E and polyphenols, which combat oxidative stress.
However, veterinarians agree that any benefit is minimal if your dog is already eating a complete and balanced commercial diet. A dog’s main source of nutrition should always be their formulated food, not treats or human snacks.
How Many Olives Can a Dog Eat?
If you’re considering offering olives as an occasional treat:
- Limit the amount: Only offer a couple of plain, pitted olives, and only as a rare treat.
- Monitor for side effects: Diarrhea, vomiting, or gastrointestinal upset is possible, especially if your dog isn’t used to new foods.
- Consider your dog’s size and sensitivity: Smaller breeds are more susceptible to sodium toxicity and digestive issues, so choose treats accordingly.
Before introducing olives or any non-dog ingredients, always consult your veterinarian — particularly if your dog has underlying health conditions, sodium sensitivity, or digestive sensitivities.
Dog-Friendly Alternatives to Olives
If your dog seems attracted to savory or salty flavors, or you need novel treats for training, there are healthier and safer alternatives recommended by veterinary professionals:
- Plain cooked turkey (unseasoned)
- Crab meat (plain and fully-cooked)
- Low-fat cottage cheese (~small portions)
- Fresh fruits and vegetables:
- Watermelon (without seeds/rind)
- Apple slices (no seeds or core)
- Pumpkin (plain, cooked)
- Carrots
These snacks can help with training, keeping dogs interested without the downsides of added sodium or fat. Use higher-value treats sparingly and always intersperse with foods designed specifically for dogs.
Veterinary Tips for Treat Safety
- Prioritize treats made for dogs as the majority of your dog’s snacks.
- Always remove pits from any fruit or vegetable treats.
- Read ingredient labels closely and avoid anything containing onions, garlic, peppers, or other spices.
- Practice moderation and monitor your dog’s response to any new treat.
- If your dog’s health status changes, consult your vet about how treats might be affecting them, especially with heart or kidney concerns.

Frequently Asked Questions (FAQs)
Q: Can dogs eat green olives?
A: Dogs may eat plain, pitted, unsalted green olives occasionally. However, marinated or stuffed green olives, and those with pits, should be strictly avoided due to added sodium, toxins, and choking risks.
Q: What happens if my dog eats a pitted olive?
A: If the pit was swallowed, monitor your dog for signs of choking or intestinal blockage. If your dog chewed the pit, dental damage is possible. Call your vet immediately for advice and observation.
Q: How many olives can I give my dog?
A: If approved by your veterinarian, just 1–2 small, plain, pitted olives as a rare treat for medium or large dogs. Smaller dogs should receive far less. Frequent or large quantities are never recommended.
Q: Are there health benefits to giving dogs olives?
A: Minimal to none, as complete dog foods already meet your pet’s nutritional needs. Small amounts of healthy fats and antioxidants may support heart health, but olives are not necessary for well-being.
Q: What should I do if my dog ate marinated, stuffed, or alcohol-soaked olives?
A: Contact your veterinarian for guidance, especially if your dog is showing symptoms of toxicity or distress. Bring packaging or ingredient lists to help your vet assess the risk.
Key Takeaways for Responsible Dog Owners
- Never use olives as a staple treat — only offer plain, unsalted, pitted olives as a rare, supervised snack.
- Avoid all marinated, brined, stuffed, or alcohol-soaked olives.
- Always check for dangerous fillers or added seasonings in any food you share with your dog.
- For training rewards, choose wholesome, dog-specific treats, or fresh safe fruits and vegetables instead.
- When in doubt, consult your veterinarian regarding any new treats in your dog’s diet.
By staying informed about ingredients and their risks, you help protect your canine companion’s health and happiness for years to come.
