Can dogs have olive oil?

Olive oil contains mainly monounsaturated fats and some vitamin E. These are healthy fats for people, but dogs do not need extra oil if they eat a complete diet. For skin and coat, fish oil provides omega-3 fatty acids that have more research behind them in dogs.

Olive oil has very little omega-3.

One tablespoon of olive oil contains about 120 calories. For a 10 kg (22 lb) dog needing around 550 calories a day, that is more than a fifth of its daily energy. Daily additions can lead to weight gain over weeks, and larger amounts can cause diarrhea.

Added oils are best avoided in dogs that have had pancreatitis.

Garlic-infused olive oil, chili oil, and herb oils are common in kitchens. Garlic oil carries garlic compounds, and chili oil irritates the gut. Bread dipping oils with balsamic vinegar, herbs, and garlic are not suitable either.

Food fried in olive oil is still fried food.

Olive oil is sometimes suggested online for constipation, hairballs, or dry skin. These can have many causes and may need proper treatment. Talk to your vet before using oil for any health problem, rather than adding it on your own. Constipation that lasts more than a day or two, or straining without producing anything, needs prompt veterinary attention. Your vet can recommend a suitable fiber source or supplement if one is needed, along with the right amount for your dog's weight.
