Dogs can eat oatmeal safely when it is plain, cooked, and served in moderation. Oatmeal is a good source of fiber, vitamins like vitamin B, minerals, antioxidants, and omega-6 fatty acids, which can benefit a dog's skin, coat, and digestive health. However, it should be prepared with water (not milk), without any additives like sugar, salt, chocolate, raisins, or artificial sweeteners such as xylitol, which are harmful to dogs. Uncooked oats are hard for dogs to digest and can cause stomach upset, so oatmeal must always be cooked and served at room temperature. The amount depends on the dog's size, with recommendations such as 1 tablespoon of cooked oatmeal per 20 pounds of body weight, served up to twice a week to avoid gastrointestinal issues.

Nutritional Benefits

• High in fiber to regulate digestion.
• Contains vitamin B for a healthy coat.
• Includes linoleic acid (omega-6 fatty acid) for skin health.
• Soluble fiber (beta-glucans) supports blood glucose regulation.

Serving Guidelines

• Cook oatmeal with water only.
• Avoid instant flavored oatmeal and additives.
• Start with small amounts based on dog's weight.
• Let oatmeal cool to room temperature before serving.
• Feed no more than twice a week to prevent GI upset.

Portion Recommendations by Dog Size

• Extra-small (2–20 lbs): 1 tsp to 1 tbsp up to twice a week.
• Small (21–30 lbs): 1–2 tbsp up to twice a week.
• Medium (31–50 lbs): Up to 1/4 cup twice a week.
• Large (51–90 lbs): Up to 1/2 cup twice a week.
• Extra-large (91+ lbs): Up to 2/3 cup twice a week.

In summary, oatmeal can be a healthy, beneficial treat for dogs if prepared and portioned correctly, avoiding harmful additives and serving it cooked rather than raw.
