Sourdough Discard Dog Treats: Simple, Healthy, 3 Ingredients
Don't toss discard — turn it into crunchy dog treats with just flour, discard, and peanut butter. Your dog will thank you.
Sourdough discard dog treats use just discard, flour, and a dog-safe add-in like peanut butter to make crunchy, healthy treats — a zero-waste way to use starter. They bake low and slow so they're hard and shelf-stable. Always check that add-ins are safe for dogs.
Recipe (makes ~30 small treats)
- 200g sourdough discard
- 200g whole wheat flour (plus more as needed)
- 80g xylitol-free peanut butter
- 1 egg (optional, for binding)
Method
- Heat oven to 325°F.
- Mix everything into a stiff dough; add flour until it's not sticky.
- Roll to 1/4 inch. Cut into small shapes or squares.
- Bake 25–30 minutes, then turn off the oven and leave them inside another 30–60 minutes to dry hard.
- Cool completely. Store in an airtight container.
Dog-safe flavor swaps
| Safe add-in | Notes |
|---|---|
| Peanut butter | Must be xylitol-free |
| Pumpkin purée | Plain, not pie filling |
| Mashed banana | In moderation |
| Shredded carrot | Adds crunch |
| Plain cooked chicken | Finely shredded |
Important safety notes
- Never use xylitol (a sweetener toxic to dogs) — check peanut butter labels.
- Avoid chocolate, raisins, onion, garlic, and macadamia nuts.
- Treats are supplements, not a meal — keep portions small.
- Bake them hard and dry so they store well and don't mold.
Frequently asked questions
Is sourdough discard safe for dogs?
Baked discard is fine for most dogs in moderation. Raw dough is not — never feed raw dough, which can ferment in the stomach.
How long do they keep?
1–2 weeks in an airtight container, or freeze for months.
Can I use all-purpose flour?
Yes, though whole wheat adds fiber. Avoid if your dog has a wheat allergy.
Even discard you'd normally toss has a use. SourdoughAI's discard tracker helps you turn every bit into something — even treats for the dog.
