Spent Grain Dog Treats: Wholesome, Crunchy, and Made From Brewday Leftovers 🐾

Spent Grain Dog Treats are the perfect way to use your homebrew mash for something tail-waggingly good. These treats are simple, hearty, and safe for dogs when made without hops or other harmful additives.

They bake up into crunchy, biscuit-style snacks with ingredients you already have on hand — no preservatives, just love, grain, and peanut butter.

Important: Only use grain that hasn’t been exposed to hops or hop residue. Hops are toxic to dogs.

Ingredients (Makes ~60 small treats)

• 4 cups spent grain (wet, well-drained)
• 2 cups whole wheat flour (or all-purpose)
• 1 cup natural peanut butter (no xylitol or added sugar)
• 2 eggs

Optional:

• 1 mashed banana or ½ cup pumpkin purée for extra flavor
• 1 tbsp flaxseed, chia, or oats for crunch and fiber
• A pinch of cinnamon (safe in small quantities)

Instructions

Step 1: Mix

• Preheat oven to 325°F (165°C).
• In a large bowl, combine spent grain, flour, peanut butter, and eggs.
• Mix until a stiff, slightly sticky dough forms. Add flour as needed to make it workable.

Step 2: Shape

• Roll out to ¼ inch thick on a floured surface.
• Cut into shapes using cookie cutters or slice into squares/strips with a knife.
• Place on a parchment-lined baking sheet.

Step 3: Bake

• Bake for 30 minutes, then reduce heat to 225°F (110°C) and continue baking for 1–2 hours until dry and crunchy.
• Let cool completely before storing.

Storage

• Store in an airtight container for 2 weeks
• Freeze for longer storage (up to 3 months)
• Treats should be fully dried for maximum shelf life

Flavor Variations

• Pumpkin Spice Pup: add canned pumpkin and a touch of cinnamon
• Banana & Peanut Butter: swap in a ripe banana for sweetness
• Savory Cheese: add ¼ cup shredded cheddar (skip if storing long-term)
