Yes, dogs can eat oats in moderation, but they must be served cooked and plain, without any added sugar, flavorings, or milk. Oats can be nutritious for dogs, providing fiber for healthy digestion, vitamins like vitamin E and B-complex, and minerals. However, raw or large amounts of oats can be hard for dogs to digest and may cause digestive problems. Dogs with grain allergies or sensitivities should avoid oats altogether. Oatmeal can be given as an occasional treat, and it is best to soften oats with hot water to make them more digestible. Always introduce oats gradually and watch for any signs of allergic reaction or digestive upset.
