1. Preheat your oven to 350°F and generously grease a baking dish—cheese can stick without proper preparation.
2. Mix spinach, cheddar cheese, cottage cheese, eggs, and water until your dog starts investigating the amazing cheesy aroma.
3. Gradually stir in flour until thick batter forms—don’t rush this step for optimal texture.
4. Spread batter evenly in baking dish, smoothing top for consistent baking and easy cutting.
5. Bake 25-30 minutes until set and lightly browned—if your pup can resist the incredible cheese smell!
6. Cool completely before cutting into squares and serving (crucial for safety and flavor development).

Notes:

• Always let cool completely—cheese retains heat and can burn eager tongues
• Amber prefers these chilled from the fridge for best texture and flavor
• Squeeze excess moisture from spinach if it seems very wet after chopping

Storage Tips:

• Store in fridge up to one week due to cheese content
• These maintain their appealing texture throughout refrigerated storage
• Freeze extras up to 3 months for long-term iron supplementation

What Makes This Recipe Special:

These squares combine iron-rich spinach with calcium-packed cheese, creating treats that support both energy levels and bone health while tasting like pure indulgence. The cottage cheese provides easily digestible protein while cheddar adds irresistible flavor that makes vegetables genuinely appealing to even the pickiest eaters.

Mix It Up (Dog-Safe Variations):
