Olive Oil for Dogs: What It Does and How to Give It

If you’ve ever added a splash of olive oil to your own salad, you might wonder if the same thing works for your pup. The short answer: yes, a little olive oil can help your dog’s coat, joints, and even heart health. But it’s not a free‑for‑all kitchen staple – you need to know the right type, the right amount, and the red flags.

Why Olive Oil Can Be Good for Your Dog

Extra‑virgin olive oil (EVOO) is packed with monounsaturated fats and antioxidants like vitamin E and polyphenols. Those nutrients support a shiny coat, smoother skin, and reduced inflammation. For older dogs or breeds prone to joint stiffness, the anti‑inflammatory properties can make a noticeable difference. A few owners also report better digestion because the oil helps coat the stomach lining.

Because olive oil is calorie‑dense, it also works as a natural weight‑gain aid for underweight dogs. Just remember that a little fat adds up quickly, so you’ll need to balance it with the rest of the diet.

How to Choose and Serve Olive Oil Safely

Pick 100% extra‑virgin olive oil – cold‑pressed, no additives, no flavorings. Regular or light olive oil is often more processed and may contain unwanted chemicals.

Start slow. For a dog under 20 lb, mix ¼ teaspoon into a meal. For every additional 20 lb, add another ¼ teaspoon, up to about 1 teaspoon for a 60‑lb dog. Some vets suggest a maximum of 1 teaspoon per 20 lb per day, but watch your pet’s weight and adjust if they start gaining extra pounds.

Mix the oil into wet food, drizzle over kibble, or use it as a tasty topper for training treats. If your dog is a picky eater, warm the oil slightly (no hotter than body temperature) to bring out the flavor.

Watch for signs of trouble. Too much oil can cause loose stools, vomiting, or pancreatitis – a serious condition that needs a vet’s attention. If you notice any of these symptoms, cut the oil back or stop it completely.

Because olive oil adds calories, you may need to reduce the rest of the food by a small amount to keep your dog’s weight stable. A quick way to do this is to subtract the calories of the oil (about 120 cal per tablespoon) from the daily kibble allowance.

Never give olive oil to dogs with a history of pancreatitis, severe gallbladder disease, or those on a strict low‑fat diet unless a vet says it’s okay.

In short, olive oil can be a simple, natural boost for many dogs, but it works best when you treat it like a supplement – measured, monitored, and chosen carefully.
