Can Dogs Eat Oatmeal?
Short answer: Yes, plain cooked oatmeal made with water is safe for dogs in small amounts. Avoid milk, sugar, flavored or instant oatmeal, and raisins.
Why it’s okay
The AKC says oatmeal can be a good source of fiber and a carbohydrate alternative for dogs sensitive to wheat or grains. It should supplement, not replace, a balanced diet. Cook it with water, not milk, since dogs digest lactose poorly, and serve it plain at room temperature.
How much and how to serve it
The AKC’s general guideline is 1 tablespoon of cooked oatmeal per 20 pounds of body weight, and for most large dogs no more than a half cup, 1 to 2 times per week. Introduce it gradually.
Risks to watch for
- Too much fiber can cause gas, diarrhea or vomiting.
- Flavored oatmeal often has added sugar and may contain xylitol, which is toxic to dogs.
- Raisins, grapes, chocolate, salt and butter should be avoided.
- Instant oatmeal is highly processed and loses nutritional value.
What to do if your dog ate oatmeal
A little extra usually causes nothing worse than an upset stomach. If your dog ate a large amount, has vomiting or diarrhea, or seems unwell, call your vet.
