Are Olives Poisonous to Dogs?

Plain, pitted olives are not toxic to dogs and rarely cause problems when given in small amounts as an occasional treat. The flesh of the olive (Olea europaea fruit) contains no poisonous compound, and the closely named ornamental shrubs 'Russian Olive' and 'Autumn Olive' (Elaeagnus species, a different plant) are also listed as non-toxic to dogs by the ASPCA. However, several real caveats apply: (1) PITS are the biggest hazard - always remove them. A swallowed pit can cause choking, an airway obstruction, or an intestinal blockage, and chewing a hard pit can fracture a tooth. (2) SODIUM - canned, jarred, brined, or pickled olives are very high in salt; too much can cause dehydration and, in rare cases, salt toxicosis. Choose plain, unsalted olives and rinse if needed. (3) SEASONINGS/STUFFINGS - marinated, stuffed, or seasoned olives may contain garlic, onion, blue cheese, spices, oils, or alcohol, several of which ARE toxic to dogs; avoid these entirely. (4) FAT - olives are high in fat, so large amounts can cause GI upset (vomiting, diarrhea) and, in predisposed dogs, contribute to pancreatitis. (5) CALORIES/PORTION - feed only a few plain pitted olives occasionally; they add unnecessary calories. Both green and black olives are equally acceptable as long as they are plain and pitted. Olives are not a necessary part of a dog's diet - they are a treat, not a staple.

Can dogs safely eat plain olives?

Yes. Plain, pitted olives are not toxic to dogs and rarely cause problems in moderation. The American Kennel Club notes 'plain, pitted olives rarely cause problems in dogs.' Give only a few occasionally, and always remove the pit first.

Are olive pits dangerous for dogs?

Yes. The pit is the main risk. A swallowed pit can cause choking, block the airway, or lodge in the intestinal tract, and biting a hard pit can crack a tooth. Always pit olives before offering them, and if your dog swallows a pit (or eats a large quantity of whole olives), contact your veterinarian.

Are salted, stuffed, or marinated olives safe for dogs?

No - avoid these. Canned and brined olives are very high in sodium, which can cause dehydration and, rarely, salt toxicosis. Stuffed or seasoned olives may contain garlic, onion, blue cheese, spices, oil, or alcohol, several of which are genuinely toxic to dogs. Stick to plain, unsalted, pitted olives only.
