Apple & Spinach Crunch Dog Biscuits - Crispy Oven-Baked Veggie Treats with a Fresh Fruit Twist

These Apple & Spinach Crunch Dog Biscuits are crispy, oven-baked treats made for occasional feeding only. They’re a great choice for dog parents who want a plant-forward biscuit with a light crunch and simple, whole ingredients. Apple adds natural sweetness and moisture when prepared properly—always peeled, cored, and seed-free. Spinach is used in small, well-cooked amounts only to add color and variety without overpowering the flavor. Combined with oat flour and rolled oats, these biscuits bake up firm and crunchy, making them ideal for enrichment, slow chewing, or breaking into smaller rewards. This recipe focuses on texture and straightforward preparation. No medical or wellness claims are made. These biscuits are designed to complement your dog’s regular diet, not replace meals.
