5 Sourdough Dog Treat Ideas Using Starter or Discard

Dogs lose interest in bland treats fast, especially when the smell and texture don’t grab their attention. Homemade options using sourdough discard solve that problem while keeping ingredients simple and budget-friendly. It also helps reduce waste, which honestly feels like a small win every time.

Using sourdough starter in dog treats gives you a soft, slightly chewy texture that most dogs go crazy for. It blends easily with dog-safe ingredients and creates treats that feel a bit more “real food” than dry store-bought biscuits. Plus, once you try these, it’s hard to go back.

1. Sourdough Peanut Butter Soft Bites

Some dogs turn their nose up at dry biscuits but go wild for anything soft and slightly chewy. These peanut butter sourdough bites fix that instantly because they stay tender and smell amazing. This is the one my dog literally hovers around the oven for, like he knows something good is coming.

The sourdough discard adds a light tang and helps bind everything together without needing extra fillers. Peanut butter brings that rich, irresistible flavor dogs lock onto immediately. The texture lands right in that soft-but-not-mushy zone, which works great for training treats too.

Ingredients

• 1 cup sourdough discard
• 1/2 cup natural peanut butter (xylitol-free)
• 1/2 cup oat flour
• 1 egg
• 1 tablespoon plain yogurt

Step-by-Step Instructions

1. Preheat your oven to 175°C (350°F) and line a baking tray with parchment paper to prevent sticking.
2. Mix the sourdough discard and peanut butter first until smooth, then add the egg and yogurt to create a thick batter.
3. Stir in oat flour slowly until the dough becomes scoopable but not too stiff, which keeps the treats soft after baking.
4. Drop small spoonfuls onto the tray and flatten slightly so they bake evenly.
5. Bake for 15–18 minutes until lightly golden, then cool completely before serving to avoid burning your dog’s mouth.

The peanut butter smell alone is enough to get tails wagging before the tray even cools. The soft texture makes it easy to chew, which is perfect for picky eaters or older dogs.

Tips

• Shortcut: Use store-bought oat flour to save time instead of blending oats.
• Serving idea: Break into tiny pieces for training sessions.
• Storage: Keep in the fridge for up to 5 days or freeze for longer use.

2. Sourdough Banana Crunch Biscuits

Dogs that love a little crunch will instantly latch onto these. Banana adds natural sweetness while the sourdough discard keeps the inside from getting too hard. My dog does that head tilt thing every time he hears these snap in half.

This recipe balances crispy edges with a slightly firm center, which keeps things interesting texture-wise. It’s also great for dogs that get bored of soft treats and want something they can actually chew. The banana smell carries really well, so even picky dogs usually give in.

Ingredients

• 1 cup sourdough discard
• 1 ripe banana (mashed)
• 1 1/2 cups whole wheat flour
• 1 tablespoon olive oil
• 1 egg

Step-by-Step Instructions

1. Preheat oven to 180°C (350°F) and prepare a lined baking tray.
2. Combine mashed banana and sourdough discard until fully blended with no lumps.
3. Add egg and olive oil, then mix in flour gradually until a firm dough forms.
4. Roll out the dough to about 1/4 inch thickness and cut into small shapes.
5. Bake for 20–25 minutes until golden and crisp, then let cool fully so they harden properly.

3. Sourdough Chicken & Carrot Training Treats

Training treats need to be small, soft, and super motivating, otherwise dogs lose focus fast. These hit all three points perfectly. My dog gets borderline obsessed with anything that smells like chicken, so this one works every single time.
