Can dogs eat Olives?
In small amounts, with care
In moderation - plain olive flesh is not toxic, but almost every olive you can buy is heavily salted, and the stone is a choking, blockage and broken-tooth risk.

What happens
There is nothing poisonous in an olive itself, and a dog that eats one off the floor is not in danger. The problems are everything that comes with it. Olives are cured, which means salt, and often a great deal of it - a routine of salty snacks is not good for any dog and is a real issue for one with heart or kidney disease. The stone is hard enough to crack a tooth, and is a well-sized object for lodging in the throat or the gut of a small dog. Then there is what olives are usually sold with: garlic, chilli, anchovy, blue cheese and marinade oils, several of which range from unhelpful to genuinely toxic. A plain pitted olive occasionally is fine. Anything from a deli counter is not.
How much is safe?
One plain, pitted, rinsed olive for a small dog and perhaps two for a large one, rarely. This is a curiosity rather than a treat worth building into a routine.
How to prepare it
Plain olives only, pitted, rinsed thoroughly under a tap to shift some of the brine. No stuffed olives, no marinated olives, nothing with garlic, chilli, cheese or anchovy, and nothing straight from a jar of brine.
Symptoms to watch for
Excess salt causes thirst, vomiting and diarrhoea, and in large quantities can be serious. A swallowed stone shows as gagging, drooling, retching, straining or a tender belly. Garlic-stuffed olives bring the slower picture of lethargy, weakness and pale gums.
When to call the vet
If your dog has eaten several garlic-stuffed olives, has swallowed a stone and is gagging or straining, or is drinking heavily and vomiting after eating a lot of salty ones.

Common questions
Are olives toxic to dogs?
The flesh itself is not. The salt they are cured in, the stone in the middle and the garlic or cheese they are often stuffed with are the real problems. One plain pitted olive is harmless; a handful from a deli tub is not.
What if my dog swallowed an olive stone?
Watch for gagging, drooling, repeated retching, straining or a painful belly, and ring your vet if any of those appear. Small dogs are most at risk of an obstruction, and the stone is hard enough to crack a tooth on the way in.
Can dogs have olive oil?
A small amount is not harmful and is sometimes used for coat condition, but it is pure fat and calories, so it is easy to overdo. If your dog's coat needs help, marine omega-3 has better evidence behind it.
