Short answer: yes. Oat flour is one of the safest, gentlest bases you can use for homemade dog treats. It's naturally wheat-free, rich in soluble fiber, and easy on sensitive stomachs, which makes it a great choice for dogs that don't tolerate traditional wheat-flour biscuits. Below I'll explain why it works and share three simple recipes you can make at home this afternoon.
I'm Preston Smith, co-founder of Bully Sticks Central. We're best known for our single-ingredient meat chews, but a lot of the dog owners I talk to also bake for their pups—usually because their dog has a touchy stomach or a wheat sensitivity. Oat flour comes up again and again as the fix, so here's the plain-English rundown.
Is oat flour safe for dogs?
Oat flour is simply whole oats ground into a fine powder, and oats are widely considered safe and healthy for most dogs. According to the American Kennel Club, oats are a good source of soluble fiber and are generally well tolerated, though they should be served plain and cooked or baked—never with added sugar, xylitol, or heavy seasoning. Because oat flour contains no wheat, it's a common substitute for dogs with wheat sensitivities. (Oats are naturally gluten-free, but if your dog has a diagnosed grain allergy, check with your vet first, since oats are sometimes processed alongside wheat.)
Why use oat flour instead of wheat flour?
A few reasons make oat flour my go-to for homemade treats:
- Soluble fiber supports healthy digestion and can help firm up loose stools. VCA Animal Hospitals notes that dietary fiber plays an important role in a dog's digestive health.
- Wheat-free makes it friendlier for dogs with wheat sensitivities.
- Mild flavor and soft texture that most dogs happily accept.
That said, treats of any kind—homemade or store-bought—should stay under about 10% of your dog's daily calories, with the rest coming from a complete, balanced diet. Baked treats are a supplement, not a meal.
Three easy oat flour dog treat recipes
You can buy oat flour or make your own by pulsing plain rolled oats in a blender until fine. All three recipes bake at 350°F (175°C).
1. Oat flour & peanut butter cookies
Peanut butter is a longtime dog favorite—just make sure it's xylitol-free, as xylitol is toxic to dogs.
- Ingredients: 2 cups oat flour, 1/3 cup natural (xylitol-free) peanut butter, 1 ripe mashed banana
- Instructions: Mix until combined, roll out on a floured surface, cut into shapes, and bake on parchment for about 20 minutes until golden. Cool before serving.
2. Pumpkin & oat flour treats
Plain canned pumpkin is a gentle, fiber-rich addition that many owners use for sensitive tummies.
- Ingredients: 1.5 cups oat flour, 1/2 cup canned pumpkin (not pie filling), 2 tbsp flaxseed meal, 1/4 tsp cinnamon
- Instructions: Combine into a dough, roll into small balls, flatten on a baking sheet, and bake 25–30 minutes until firm. Cool completely.
3. Apple & oat flour bites
- Ingredients: 2 cups oat flour, 1 finely grated apple (no seeds or core), 1 beaten egg, 1 tbsp honey (optional)
- Instructions: Mix, spoon small portions onto a lined sheet, press flat, and bake about 25 minutes until crisp. Let cool before serving.
Store baked treats in an airtight container for up to a week, or freeze for longer. Because they're preservative-free, keep an eye on freshness.
Homemade treats vs. single-ingredient chews
Baked oat flour treats are perfect for training and quick rewards. For longer-lasting chewing—the kind that keeps a dog genuinely occupied and supports dental health—I still point people toward single-ingredient chews. Our chews are 100% natural, 100% real meat, fully digestible, and contain no rawhide, ethically sourced from grass-fed American and Argentinean farms. If you're weighing chew options for a sensitive chewer, our guide to safe, digestible chews is a good next read. Many owners use both: a homemade biscuit for training and a natural chew for downtime.
Frequently asked questions
Can dogs eat oat flour every day?
In moderation, yes. Keep treats to roughly 10% of daily calories and make sure the bulk of your dog's nutrition comes from a complete, balanced diet.
Is oat flour good for dogs with sensitive stomachs?
Often, yes—its soluble fiber is gentle on digestion and it's wheat-free. Introduce any new food gradually and watch for changes in stool or appetite.
What should I never add to homemade dog treats?
Avoid xylitol, chocolate, raisins/grapes, onion, garlic, excess salt, and added sugar—all of which can be harmful to dogs.
