Peanut Butter & Banana Crisp Dog Biscuits – Crunchy, Naturally Sweet & Irresistibly Nutty

These crisp biscuits combine two dog-favorite flavors—banana and peanut butter—into a wholesome, crunchy treat that’s both satisfying and nutritious. Bananas provide potassium, fiber, and natural sweetness, while peanut butter (xylitol-free only) adds healthy fats and plant-based protein that help with satiety and flavor. Baked until crisp, these biscuits are perfect for dogs who love a good crunch and for owners looking for clean, simple homemade treats.
