Can Dogs Have Olive Oil? Safe Amounts & Pancreatitis Risk

Can Dogs Have Olive Oil?

LIMIT

LIMIT — A small drizzle of plain olive oil now and then is generally fine for healthy dogs. It is pure fat, so too much can cause diarrhoea or pancreatitis; skip it for dogs prone to pancreatitis.

Olive oil is not toxic to dogs, and a small amount occasionally is considered low risk. It is pure fat and calories, so it should not be added regularly without your vet's advice.

The full answer

Olive oil is a plant oil rich in monounsaturated fat. It is not toxic to dogs, and a drizzle over food is sometimes used to make meals more appealing or add a little shine to the coat.

It is pure fat and calories, though. Too much can cause diarrhoea and weight gain, and fatty foods are a risk for dogs prone to pancreatitis or those that are overweight. A dog on a complete, balanced diet does not need extra oil.

Other cooking oils are broadly similar in being pure fat, and oils used for frying are often heated and seasoned. Chilli oil, garlic oil and flavoured oils are unsuitable. Ask your vet before adding oils to your dog's diet, especially if your dog has any health conditions.

Is Olive Oil Good for Dogs?
