Tuna & Oat Crunch Dog Biscuits – Savory, Protein-Rich Crunch with Gentle Fiber

🐾 Why This Recipe Is Good for Dogs
These crunchy biscuits deliver a savory protein boost using tuna paired with digestion-friendly oats. Tuna (packed in water, no salt) provides lean protein and omega-3s that support skin, coat, and brain health, while oats contribute soluble fiber for steady energy and gut comfort. Baked to a firm crunch, these biscuits are ideal for dogs who love bold flavors without heavy fats or additives.

🛒 Ingredients (dog-safe only — no toxic foods)
